Planning Sidewalks And Planting Beds (How Big Do Planting Beds Need To Be?)
Since I’m in a holding pattern with my storage room (waiting for my contractor to do the new subfloor and drywall) and with the dining room right now (waiting for drapery fabric to be delivered, waiting for air-dry clay to be delivered, waiting for inspiration to hit for the gallery wall and new benches, etc.), I decided to head outside yesterday and start marking out the walkways and planting beds for the front of the house so that I could get a visual of what these might look like in our actual yard.
I started with my landscape design as a reference. On the landscape design, the designer has the walkways coming off of the front sidewalk covering the curved area of the main sidewalk.

I had always envisioned those gentle curves continuing and veering off into the side walkways. But when I marked that off, I didn’t really like it.

So instead of trying to continue the curve, I ended up coming straight off of that point where the curve meets the corner on the sidewalk. I liked that look much better.

But one thing I’m still not sure about is the placement of the walkways. Here’s a closer view of how the designer arranged the walkways coming off of the sidewalk. You can see that the walkways connect at the curve.

I don’t dislike that, but the issue is that if I go with that plan, that gives me a planting bed in front of the porch with a depth of about nine feet. That seems like a really deep planting bed to me.

If I go the opposite direction with the walkway, that gives me a planting bed that is about five feet deep. That seems more manageable to me.

But I don’t have any experience with planting beds, so I’d love your input. Larger planting beds means less yard/grass to take care of, and I do like that idea. But nine feet just seems extreme to me.

I’ve enhanced my paint lines in some of these pictures so that you can see them better. Hopefully you can see this one with just the paint lines so that you can see how the walkway would curve around the area in front of the breakfast room windows.

And then I would have another five-foot-deep (or nine-foot-deep) planting bed in front of the studio, depending on if I keep the walkway where it’s marked off now or move it towards the street like the designer shows on the landscape plan.

If I go with the five-foot depth, the walkway coming off the sidewalk would look like this as you’re approaching the front door.

And the other side is where it gets tricky. If I stick with that five-foot depth for the planting beds in front of the front porch and my walk-in closet window, the pad that is poured for the steps to the bedroom would look something like this so that it meets the walkway. Keep in mind that I’m limited in the width because of the cleanout for the sewer line and the gas meter.

Just a note: The walkway won’t dead end at the end of the house. It will curve around to the side of the house, but I ran out of spray paint and daylight, so I stopped at the end of the house.
If I go with the nine-foot depth for the planting beds, that pad for the steps ridiculously long. It’s very hard to tell if this would actually look awkward or if it would look nice. With it just being orange lines, it looks crazy to me. But I’m sure once it’s done, and there’s just concrete and no orange lines, it would just look like a normal walkway leading to some steps and a door. It’s just hard for me to picture in my mind.

So at this point, I’m leaning towards the walkways being closer to the house and having five-foot-deep planting beds in front of the porch and my walk-in closet window. But I could certainly be persuaded to move to closer to the street, just like the landscape designer planned, if you experienced gardeners think that it’s better to have the planting beds nine feet deep instead of five feet deep. Or maybe the decision doesn’t depend on the depth of the planting beds. Maybe it would just look better to start the walkways in the curve of the sidewalk instead of after the curve. So if that’s the case, you can let me know what you think.




Hi Kristy. I think the depth of your planting beds depends on what you want to put in them. If you put some bushes that will get larger, I think they would fit nicely in a 9′ bed. They may start out small but after about 3 years they may be remarkably larger! If you are only thinking of flowers, then I think the 5′ depth would be plenty. My vote is larger with some flowering bushes. I have hydrangeas but not sure what would do well in your zone. Good luck.
I agree with Suzanne. We were new to gardening when we bought our house. We started with 4 ft beds which seemed HUGE at the time. But then we quickly realized that it didn’t give the foundation or the bushes any room to breath as they got larger. We’ve expanded the width of our beds twice and we’re loving the extra room. The bushes have room to get larger and not expand over the sidewalk or push up against the foundation, and we have some room to infill with fun annuals or other plants.
I would vote for smaller planting beds. I feel like weeding and maintaining planting beds takes a lot more work than just mowing grass, And that’s a lot of planting bed space to keep on top of! I think the plan is beautiful, but time and reality have to be taken into consideration 😆
What she said. You can use weed barrier, but they’ll find a way through -Texas weeds are strong. And mowing in the area (even with a sidewalk) will start grass growing in your planters. And the amount of mulch to try to prevent that ……
Larger planting beds means more weeds to pull and control. Suzanne’s comment makes some good points. Mowing is easier than weeding. Good luck!
We have deep bed. The bushes take up a lot of room. The deeper beds would work better. You can still plant flowers. But the bushes will be the backbone of your beds.
I second this. Shrubbery will fill in and choke out 95% of weeds under them. They will offer year round greenery. The space in front depends on your level of gardening interest. You can work to establish perennials to enjoy year after year, plan and plant annuals as the seasons change, or do a mix of both.
The 9 feet give the bushes room to grow without growing onto your side walk. Perhaps check on the plants that are depicted in your garden map. You may find that they need the space for growth. Just like remodeling gardening gets uglier before it gets beautiful! Lol

The older I get the less annuals I plant. I do think they’re lovely in a more narrow bed but the yearly expense of them is something I’m starting to get away from. Although perennials are expensive it’s many times one expense. They do require some maintenance but it’s not too bad. I think you need the larger bed if you do perennials. I don’t think the longer walkway looks odd either.
Im by no means an experienced gardener, but one thing I have noticed is non- experienced gardeners doing is not allowing room for plant growth and whatever else is in that space, for you, walkways and in particular room for Matt’s wheelchair. Just an FYI, I have never had a plant follow the growth charts on the tag. This is fine, but consider what maintenance it will take to keep the paths clear if the plants over shoot the growth pattern and how close you planted to the path. Are you planning to plant the suggestions? Obviously, those plants are filling in the nine foot space. Cutting that space in half, that planting arrangement would change.
Hi,
I love your 5 feet deep idea better. I would add curves to the little path that goes to your bedroom door instead of straight. I would add a path where the dinning room window is for the seating area, with the same curves as the bedroom one, that will join to the main path. I don’t know if it makes sense…
I also like the idea of some curves in the left side of the house going toward the bedroom.
Look at the mature widths of the plants you’ll be using. That will determine the size needed for your planting beds.
Why don’t you go to a garden center and look at some of these plants on your plan and talk to a gardener there? It looks like you have some shrubs and even a small tree. It is easy when it is empty to think it is big but once you put some plants in there, they may be going over the sidewalk at their mature with. You want some structural and some things that bloom seasonally. That means shrubs.
Rather than use the fabric to deter weeds growing, I’ve had a great deal of success with several layers of newspaper. It’s cheaper and better for the soil.
Ah, yes, reminds me of the book Lasagna gardening! Newspapers decomposing encourages worms, a gardener’s best friend.
If I had stayed I’m my Ohio house, I was going to start a worm farm in my basement. Best soil there is😉
((Now that we’re in Az, I miss all the Midwest plantings I had. There’s not much that grows here that’s non-native.))
I’m team larger beds. Someone once told me that the key is larger, mounded beds. I started paying attention and noticed that the homes that had really invested in landscaping (whether they did it themselves or hired the work) used larger beds and mounding inside the beds.
One thing to remember is that it’s best to keep some distance between the plantings and your house. I have not done that, but know I need to. So that would use up some of your space. I think the space is good not only to reduce pest pressure, but also breathing room for the plants. Air circulation is good for their health, but it also looks good. You could think of a bush next to your home in the same way that shoving a sofa against a wall is not recommended by interior decorators.
My only input is 1. Make the beds wide enough that you can leave plenty of room between your foundation and the plants, and 2. before you pour the paths, put a conduit underneath, so you can run water or power under the walkway without having to damage the concrete.
Lots of yard work exp here. When putting in garden beds consider what plants you’ll use, how much they’ll cost when thinking of the size of the beds. First glance, those big beds look like they’re going to cost a fortune to put in. It’ll take awhile for them to fill in as well. Please check this all out before jumping in the deep bed of the pool!
Contact your landscape designer and ask him to send you elevations of the front of your house, so you can see what these trees, shrubs, and plants will look like when fully grown in and mature. This will give your the viewpoint you need to decide.
If you go with the smaller planting beds, you will need to change the planting plan. You will not believe how big some of those shrubs will get!
If your designer can’t give you an elevation, feed the info into ChatGPT. It will give you an approximation.
Hi Kristi,
I just went out to measure one of my garden beds. I wish I could figure out how to send you a picture of it. The bed has 2 hydrangeas in the back, several pots of flowers in the middle and coral bells along the front edge. There are a few other perennials in the bed too. My bed is 12 feet deep.
Has your landscape designer put some bushes for year round interest in the beds? I find that bushes take up more visual and actual space in a bed. When I originally planted my beds, I packed in more plants than I now have. After a few years, I needed to thin things out or there were too many plants.
When you do start planting, think of a 3 year plan……..the 1st year the plants sleep, the 2nd year they creep and the 3rd year they leap. Its just a silly rhyme to help me remember not to plant things too close together and to try to be patient! At first your beds will look puny, but it’s okay.
So my recommendation would be to have 9 foot beds. Good luck!
Excellent recommendations!
Many shrubs grow to be 3-5′ around, filling a 5′ bed with no room for flowers. I say this as a gal who planted a twig of a $9 Japanese maple from Aldi in 2018 that’s 5′ across now, and threatening a narrow walkway, and a few small 1 qt frost proof gardenias in 2021 are now are 3′ across with room to grow.
So look at the plants they show. Varieties of what the plan says, can differ to what you find locally. If your yard has a ton of water, they’ll grow bigger or not thrive. Decide if you like them, them look at their mature size, then height. Many plants have smaller and bigger varieties, and you can get lost finding the right variety like a paint color.
Establish flashcards on what was called out, take notes (stay/revise/no, plan size, local height/width) so you have the notes all together. You ignore certain plants to have a narrower bed. On rainy days research, water needs, and sun/shade how to fill it in.
For working out paths visually, Try a stiff bright hose (or pool noodle), stiffer ones smooths out curves well, and show in pictures easier. Then when good lay stakes for straight lines paint the curves.
Hey Kristi,
I think you will hear the same thing over and over. It 100% depends on what you are planting and the expected size of the plant!
9′ gives you room for a nice full bush in back most types hit 4-6′ diameter even on the little ones eventually.
Allowing for layers and texture and depth, and color. I think you will appreciate the space once you get into the actual plants.
I know it is especially hard when planting the little babies, but the spacing is there because they will fill it in!
Have you walked around a nursery with your plans in hand and evaluated any of the suggested plants in person?
It would be very eye opening for you I think to get things planted and see what they look like a year later. 🤯
Can’t wait to see!
I agree you need visuals and should go to landscape designers and architect websites to see why your design calls for 9’ deep. Your yard is deep and plants will get swallowed and not look balanced in relation to the grass and trees. Deborah Silver and Co is a favorite of mine.
I would definitely go for the 9 foot flower beds. I don’t know if you still follow Laura from Garden Answer (thank you for introducing me to her videos several years ago!), but I’m sure she would also suggest going larger than 5 feet. You can always layer plantings in that space (taller in back, shortest in front), and the more plants you have that “meet”, the less weeds you will have overall once they are established. I DO NOT recommend rock as your mulch. I live in Illinois and my flower beds with rock bake my plants and we have to constantly watch them in the heat. I can’t imagine having rocks as mulch in Texas. My beds with regular mulch are much happier. Five feet seems deep, but that space will fill in very quickly as shrubs/plants mature.
As far as the walkway to your bedroom door, you can choose your plants for that area to draw the eye away from the sidewalk leading up to your door. Adding visual interest away from that area will be key. I’m excited to watch this next chapter for your home evolve!
I am a Master Gardener with 30 years of experience in multiple states…I really encourage you to follow your landscape designer’s plan and start small!!! Two beds at a time in your most prominent area for enjoyment and visibility will make it seem less like work and more like fun! All the readers saying look at max growth are right! A wee potted plant can get quite big with proper conditions. Look online for your county extension service-they should have tons of info on how to amend soil, what grows well, native plants, etc etc etc. Don’t take on too much as getting things established takes time and effort. Mulch is your friend to keep weeds down and moisture at root level. Good luck and hope you enjoy it!!!!
Celine,you made me think of something else; the Extention Service might do soil testing too. It’s looked pretty dead since nothing has been there for years. Once tested you can get a better idea how to amend it.
There’s a ton of great advice in these comments.
Well Kristi… curved paths & pant beds…have always been my choice…they seem perhaps harder to mow around, but a grass side boarder placed just inside of the outer edge of the plant bed, perhaps of flat side up bricks …again just inside the edge of the plant bed… leaves a perfect place for the one of side wheels of the mower to rest on and NO ADDITONAL POST MOWING TRIMING would be necessary!
It depends on what you want to plant and how much work you want to do to maintain them. I have beds of varying sizes but most are definitely no deeper than 5 feet. I have some smaller bushes in the back and then lower height flowering plants in the front. In TX, that might be azaleas and ti plants and daisies or begonias. If you don’t want to regularly trim or shape bushes, a narrower bed would be better. I have just roses in a bed that’s about two feet deep along my front fence and that’s perfect for that one. My deep bed has a mix of bushes, ferns, and hostas (I’m in Oregon).
For the sidewalk, I am bothered by the shape with the side walkway not meeting the curve. I’m wondering how it would look to either have the sidewalk start wider at the connection point and then narrow or to have it connect in two places then meet and use the little space between the connections as a defined planting bed for a single plant or planter.
Hi Kristi,
I have 2 thoughts. First about the plants being close to the house. I was told that for fire and also for painting you should always be able to walk next to the house. Second, as far as your sidewalks would you be curving it at your junction locations for easier wheel chair turns?
Also, I have stepping stones right off of my front door steps, they are okay but one day I will move them out so it won’t feel like a sudden turn coming down the steps. I have 3 steps.
There are pros and cons for each plan. Looking at the photos with orange markings, it doesn’t appear there’s 5′ of space between the porch and proposed walkway but I trust you measured it. That depth would to be enough space for planting one shrub between the porch and the walkway and also between the walkway and closet/laundry. This may look a bit stiff, like a row of soldiers lined up. If you could find pots from shrubs or something similar and place them in front of your porch you may get a better feel for how it will look. Our garage extends from the front of our house. There’s a walkway from the driveway to the front porch which created a landscape bed approximately 14′ x 14′. There are 17 shrubs planted there along with 3 large rocks and a metal armillary sculpture with wood mulch. On the other side of the porch there’s a bed about 17′ wide at the house curving down to 10′ wide where it meets the walkway. It’s about 10′ deep at the corner of the house and 20′ deep along the walkway. I am guessing there are about 27 shrubs and 2 trees along with an area for annuals. I like the look of the deep landscape beds but it does take some work trimming the shrubs, replacing the mulch every two years (8 cubic yards including the beds along the sides and backyard of the house) and occasionally weeding.
Your beds are way to close to the house for someone living in termite country. I wouldn’t plant anything or put mulch within 2-3 feet of the house. I know it seems like a lot but when you do foundation plantings, they’ll grow to fill in a lot of the space but leave enough so the plants don’t contact the house and you can get behind them to prune. I have a 24″ rock bed next to my foundation and the first bush is planted 3 ft out. I live in a brick house on slab, not a post and beam. You should look at the landscape designer’s plans as well as talk to people at your local nursery (and I don’t mean Home Depot) to get some ideas. It doesn’t look like you have gutters so think about bushes that aren’t highly susceptible to fungus. What size and height do you want your foundation plants? Do you want to keep the ones in front of the porch/windows low? If so, don’t plant bushes that grow to 8-10 ft or you’ll spend a lot of time pruning to keep them small; ditto for shaped plants like boxwood. Once you’ve figured out your foundation plants and what their eventual size will be, you can fill in with perennials and annuals and that will help you determine the best depth of the beds. Don’t forget that not all perennials are small; evergreen daylilies (don’t use any dormant varieties, it’s not cold enough in Waco), agapanthus, garden phlox etc. are fairly tall and can spread. You also need to consider what’s getting hot afternoon summer sun vs shade. I tracked the sun at my new house this summer to know what I could plant where this fall that won’t be killed off next July. When you have decided what you want and where, you can design your irrigation system for it. There are plants like hollies and liriope that do okay without it but pretty flowering plants generally don’t. I’ll finish by saying don’t put your sidewalks in until you have your beds figured out. Beds can grow or shrink, sidewalks are limiting and expensive to move.
Knowing your sun/shade patterns in different seasons is also a key factor.
I’d also deal with a reputable nursery for the more expensive foundation plants or shrubs and use Home Depot/Lowes for annuals or less expensive ones. And ask the nursery staff if they have at least a year guarantee.
If not I’d go elsewhere.
The landscape designer probably included a list identifying the various plants in his/her design. The design was not cheap and should have recommended plants for your area. I highly recommend using the suggested plants. Take the design and the list with you to your local nurseries to see the recommended plants and get current prices at several. I’m not recommending them, but in the past, Home Depot offered a one year return policy on dead plants; just something to consider since plants are expensive.
It will remain hot (and possibly dry) in Waco until November. Don’t plan on planting anything until then; in the meantime, get the necessary soil and compost brought in and the beds built. Those two alone are more expensive than most of us initially estimate, and will take several days minimum to accomplish. I’m located in Montgomery, Tx so our climates are similar and I speak from experience.
My first impulse was smaller beds, but as I read the other comments and thought of my own beds, I realized you will be happier with the deeper beds, following the design you already have in hand. Try to stick to as many of the recommended plants as possible. I used a designer with different plants, and they failed for various reasons. The nursery had no guarantee on the plants so I was out hundreds of dollars.
My vote is 9′ beds. You would be surprised how large even a dwarf variety can get. I planted some “dwarf” loropetalum shrubs and they quickly outgrew the area they are planted in. It is possible they were mislabeled. I used an extension cord to lay out my flower beds. That way you can change the curves as much as you want to. Also the suggestion about conduit is spot on. You don’t want standing water near your foundation.
Listen to the Master Gardner! Follow your plan, you hired him for his expertise. When you start planting they will seem small and beds will look empty do not give into the urge to plant more!
The primary landing may look better with a slight swoop meeting the sidewalk
I don’t know enough to help with landscaping but are uou putting in an ungrounded watering system or planning gon watering it by hand.
Here’s my 2 cents from decades of gardening. Compost, compost, compost. It is your friend. You can never have enough of it. Keep adding compost as your mulch. Don’t use rock as mulch, and don’t use a plastic weed barrier. Consider having your front walkway widened to be the same width as the concrete by the front steps, removing those odd curves. Pathways should be at least 4 feet wide for 2 people to walk side-by-side comfortably (and when they’re a little wider it’s OK if plants overlap them to soften the edges). Do you plan on using those lateral pathways very often, or are they there primarily to be a border between beds and lawn? Concrete does not need to separate beds & lawn, and paths can be placed inside both beds and lawn! Define their purpose first. Your design plan looks very ambitious, but really ask yourself, “How much gardening have I done in the time I have lived here?” Plants are expensive and your soil seems unhealthy (sorry, it does). You might want to consider sewing the entire area in crimson clover to loosen the soil, add nutrients, and smother weeds which might pop up when the weather cools. Mow it down after blooming and before new seed sets, then till it under with a nice layer of compost on top. Your garden will thank you.
I’d say trust your landscape designer. You paid for their expertise, use it. The smaller beds don’t leave enough room to layer your plants. Layering is what gives a full lush feel. Smaller beds look very flat and lack that designer look. Since you don’t have any experience and lack experience,Trust the professional!
I have a few thoughts! First, you will spend 75% of the landscape budget on soil amendment, compost and good soil, and 25% of the budget on actual plants. I know that sounds crazy but it will guarantee a more successful planting in the beds that haven’t seen nutrients for a long time. Second, the sidewalks would look less harsh initiating from the curved areas. Third, the foundation plants should ideally be some sort of evergreen so you have year round softness. The distance between the plants at full maturity size and the foundation of the house should be 1/2 to 1 foot away from the house. This means some shrubs need to be planted 2-4 feet from your foundation at time of planting. If using 5 feet for depth the beds will eventually look too small.
Fourth, and I don’t think anyone has discussed the actual size of your front yard. While either sized beds would look beautiful, the scale of the beds to the house and how it relates to the size of the yard has been considered when the professional landscaper created your plans. I would recommend the bed sizes on the plans. You can always add or remove dirt but wait until after planting prior to adding a permanent sidewalk. As a side, large rocks and other hardscape look stunning in landscape!
Wider beds are better bushes do grow quickly, and you have to have room to even work in those areas to plant a few annuals or trim bushes. You are in the planning stage but once concrete is poured your design is set. The idea of putting a conduit under the sidewalk for sprinklers in the planting beds is wise, then you are not outside watering the plants all of the time. Someone suggested a concrete path to the seating area, but you could use flag stones or even pea gravel for that area to see if a concrete path is even necessary.
I left my comment on your Facebook post, but I will add here that the walkway needs to come off the curved space, as he’s shown, because you really wouldn’t have enough room for plants (shrubbery) in front of the porch. Even the smallest Boxwoods will grow to minimum 2 feet, and you need to leave room between them and the porch in order to do any maintenance to them or the porch. The beds may look large, but he has a lot of plantings, various sizes that will need room to grow. I always have to fight with my husband when it comes to plantings. He wants 3-4 ft, away from the house, but it doesn’t work with the plants I want! I gave in to him, and now he complains that the shrubs are too big and wants me to scalp them! Give them room to grow according to their tags, and don’t design the beds until you’ve checked out the plants MATURITY that you want to buy!
Spot on advice! Always take into consideration the mature height of anything you plant.
I don’t know if you plan on planting your beds exactly like the paper plan, but were it me, I’d want more breathing room between plantings. This gives you someplace to walk and the eye to rest. It could be mulch, a curvy dry river rock bed, or pea gravel. So a larger bed is not a bad thing.
I always had a cutting garden too which you might want to put in the back; they can get leggy and not as esthetically pleasing to the eye. I didn’t care so much about that, I needed the extra sun the backyard got for them.
Five feet is plenty deep for a nice border bed in front of your house. Especially with as much frontage as you have. When considering 5′ vs. 9′, the most important question you need to ask yourself is how much time can you realistically dedicate each week to keeping the beds maintained (deadheaded, weeded, watered, etc)? As for the walkway/pad from the bedroom door, adding a little flare at the end of the pad where it meets the pathway in front of the house might make it look more substantial. It will also add some nice curves to otherwise straight lines.
Any size you want them to be! And they can change over time.
Your orange idea looks better than the landscaper’s plan. A 9-foot flowerbed is crazy, it looks good on paper, but in reality, not so much. Even a 5 ft flowerbed is large. We had a country home with a 90 ft by 5 ft bed across the front yard. That was so much to take care of. I’m think about a 3 ft bed that you can easily maintain…seriously. Your curve going to the studio looks very good. Instead of all that space by the breakfast room windows as flowers, make a small patio to put that chair on with some pretty outdoor fabric pillows. No water feature, Kristi. That way you don’t have so much flowerbed to maintain. Trust me, mowing the grass up the to edge of the bed is less work that pulling weeds out of the bed. If you have a sprinkler system put in you will have nice deep green grass and the front yard will be beautiful. A bed around the big tree would look nice. A narrow bed on the other side of the house will look fine up to the steps by the door. I’d have a “landing” and a ramp poured instead of steps.
When i lived up north I used to buy all my spring plants at home depot. They were healthy plants
Then we moved to hot Florida and plants are different here
Also they have less plant choices
You can use there web sight looking for plants. They have
Choices I am lookinh for
.and.best of all they deliver to your home for free.
Plants are very healthy. Hope this works in your state.
I agree with all the comments about 9 foot beds. Listen to the Master Gardener comment. Please do not use fabric weed barrier. It’s so unhealthy for your plants and the weeds grow right through it. Your mulch needs to be very thick. Although it’s expensive, you won’t regret it in your hot Texas heat. Follow the advice of the conduit under the sidewalk. There’s an old saying amongst gardeners, “ if you’ve got weeds, you don’t have enough plants”
I’m sure its just me, but big planter beds to me means lots more shrubs and things to have to trim, more mulching… more weeds to keep under control. Yeah, it all looks pretty in a picture, but I had to stop all that when my shoulders got bad. I am amazed at the HGTV show where they go in and redo a forgotten lawn that the person can’t take care of… and then proceed to plant 200 plants!! I don’t know of anything that requires no care. Someone please correct me if I am wrong…because I have had to let my planting beds go back to grass. I’m sure whatever you decide it will be beautiful.
Martha, many shrubs require minimal work. People seem to think they need to go out and trim something which shows they are now “gardening.” I think the first thing Kristi needs to decide is if she is landscaping or gardening. Landscaping in most people’s eyes is a one and done thing – like painting a room. Gardening is an ongoing activity. Those that are advocating shallow beds probably don’t enjoy “yard work.” Deeper beds are craved by those of us who enjoy the journey. Deep beds, gently meandering paths, compost, seasonal change, excitement with new varieties old favorites – those are the delights of true gardeners. To us it’s not yard work, it’s our hobby (and passion).
Shrubs? Deep bed
No Shrubs? 4-5 feet will work.
Remember you don’t want shrubs that will rub against the siding — they need to be placed a distance from the house.
