We all have that one wall or fence that isn’t adding anything to the garden’s beauty. Or perhaps space is limited, and we have no choice but to grow up rather than out. There are plenty of solutions to these problems, of course. A bright lick of paint here, a strategically placed climber there. But what if an entire mini-garden with many colorful and varied plants could inhabit the space instead?
Tired, dull, vertical spaces can be transformed relatively quickly and easily by planting some carefully chosen varieties at the right time of year. This is where a plant wall or ‘living wall’ can come to the rescue.
Another advantage is the choice of plants that can be adapted to this growth. Bright, flowering annuals, grasses, perennials, and even fruit and veg can all thrive when planted vertically. There are so many exciting possibilities!
So how can you get started building your own gorgeous new plant wall? Below, I’ll lay out my step-by-step advice on setting up and planting the wall, and I’ll also clue you in on my suggestions for 25 of the best varieties of plants to include in your wall.
Steps on Setting up Plant Wall
Step 1. Select the structure you’ll build on.
You have options as long as the surface you want to attach your framework to is reasonably solid. I’d recommend a sturdy fence, garden shed, wall, or even straight onto the side of your home. A word of warning, though; if using your house wall, you may want to fix a waterproof liner between your home and your framework.
This will prevent any moisture ingress to your home and ensure all your watering goes where it’s supposed to – the plants!
It’s also important to consider the aspect of your wall. Does it catch the sun for most of the day, or is it on the shadier side? To get the best out of your wall, you’ll need to know this to pick plants that will thrive in the area you have.
Step 2. Attach your frame and planters.
Once you’ve selected a suitable area, it’s time to attach the framework for your plant wall. If you’re handy, you can, of course, DIY the framework of your wall. The aim is to cover the frame with lush plant life, so you can use any old trellising, timber, or wire you have spare to construct it.
As long you can attach your planters, you can get creative.
But don’t worry if woodworking isn’t your strong suit – plenty of decent, pre-made frames are available at most garden centers or online.
These come in many different formats, from pouch systems, which give you dense and uniform plant spacing, to frames with individual planters that you can attach randomly, giving a more natural, flowing result.
Some versions even come with interconnecting planters and reservoirs so that water and feed can be distributed through your entire system quickly and efficiently. If you choose this option, remember that different plants have different needs, so you will do well to bear that in mind when deciding what to plant.
Step 3. Attach the planters.
If you’ve opted for a pre-made frame, it may be complete with planters attached. In which case, you can get straight to plopping your plants in! If you’re DIYing it, you can get creative with the containers you use.
Why not get the kids involved and upcycle some old coffee cans and containers from your home? Once you have drilled a few drainage holes in the bottoms, these can be colorfully painted to compliment the blooms you are planning and fixed onto your frame to add a bit of character to your wall.
I love doing this, as the kids take an interest in how ‘their’ pot is growing, and it encourages them to help with the ongoing care of the plants.
Step 4. Select your plants.
Here comes the best part – filling the blank canvas of your frame with an abundance of greenery and color! There is no limit to the variety of effects you can create. You may want to keep things wild and loose with grasses, ferns, and ivy.
Or you could go for a desert theme with succulents and cacti. Designing your wall is truly something you can and should have fun with. However, there are a few factors to consider before you get stuck.
Growing requirements.
Plants are like people. They all have their specific preferences, and some can be pretty fussy! Therefore, I highly recommend selecting plants that you know have similar needs for light, shelter, and moisture. This will make your job much easier for maintaining and caring for your plant wall.
Size when mature.
You’ll want the plants on your wall to complement each other and look great. Therefore, you’ll need to choose varieties with similar sizes when fully grown. I’ve seen plenty of design projects that look great when planted but soon lose their impact when one plant starts towering over the rest!
When do you want it to look its best?
One thing I always consider when planning the planting for a new area is the time of year that I want the best display from the plants. Annuals are the obvious choice if it’s a big, bold summer show that you’re looking for.
Boisterous Begonias and pretty Pelargoniums never fail to catch the eye. Or, if you prefer a bit of year-round interest, hardy perennials like Heucheras, ivy, and Vinca are a great option.
You can even use the space to grow an edible crop; in this case, you’ll want to stagger the harvest times of your plants so that you get food for longer.
When to plant.
You can grow many plants from seed very cheaply or buy them as plugs in the spring and plant them straight away. Spring is, without a doubt, the best time to start building your plant wall.
Warmer temperatures and showers provide peak growing conditions, and your newbies will pour all the energy they soak up into establishing themselves in their new homes.
Just be sure to protect young plants with garden fleece if the nights are still cold in your area.
Step 5. Caring for your plant wall.
Once you’ve spent time and effort selecting your ideal plants and settling them into your wall, you’ll want to ensure they get the best care to keep them looking fantastic. Maintaining your plant wall is similar to caring for hanging baskets or potted plants.
All of its needs must be met by you. There is no natural moisture in the compost, and the rain will not penetrate the umbrella of foliage enough to irrigate it, especially for the plants near the bottom of the wall.
So regular watering, at least every 2-3 days, or even daily in parched weather, is essential. Depending on your selected plants, your wall may also benefit from a feed every few weeks.
This applies particularly to things like flowering annuals and fruiting plants. Although many composts are sold with added feed mixed through, all the summer watering you’ll be doing can wash this through and out of the soil before it reaches your hungry plants.
I’d recommend giving fruiting and flowering plants a regular feed with a potassium-rich product like Tomorite or Miracle-Gro. This will encourage an abundance of beautiful blooms and juicy fruits.
