Our Holman GreenWall range is the new way to gardening.
Are you living in a smaller space or an apartment where ground gardening isn’t available, but you still want to grow edible or decorative plants? Or perhaps you may have exhausted all the ground space available for gardening but want to add even more green into your life? At Holman we are leading the way with clever growing solutions that work in non-traditional applications – like growing on a wall!

Sunlight & Water
Before starting your project consider the amount of sun your area receives. If you have eaves or a veranda, check how the sun exposure changes during the day making sure the wall you want to mount on still receives enough sun. Full sun (5+ hours) to part sun (3+ hours) gives you a lot of variety of plants to choose from. If you experience very hot summers, a mild morning sun position is preferable to a hot afternoon sun position. Also consider where your water source will be and how easily you can run a hose from that tap.
Make sure you group your plants by their sun and watering requirements. For example, you don’t want to plant sun loving and drought tolerant succulents with shade and moisture loving ferns in the same GreenWall. You should also group edible and non-edible plants together, and not mix them on one wall. Refer to our plant selector chart below if you need assistance with this.
STEP 1: Installing the GreenWall panels
- Determine how many panels you want to install.
- Once you have determined where your first panel will be located you hold it against the wall and get it level (use a spirit level). It is most important that you get it level if you are going to add more panels because a small level error will magnify as the line of panels grows longer.
- Next you need to mark the wall to position the holding bracket.
- If attaching to a solid wall such as brick or concrete, use a 6.5mm masonry bit to drill all three holes.
- Insert the plastic wall plugs which are supplied.
- Fix the bracket to the wall using the stainless steel screws provided.
- Hang the panel onto the brackets.
STEP 2: Installing the irrigation system
- Install the watering system by locating the poly tube with the drippers in the top bracket. This will allow the water to drip through the distribution holes in the panels and leaving a wet puddle in the recess in each panel.
- Place the drippers between pot 1-2 and 3-4. If some drippers are not working well, you can unscrew or slightly loosen the cap of the dripper.
STEP 3: Mixing up your potting mix
- Break up the coir peat in a bucket and water it down. Let it stand to absorb the water. Check every few minutes to see if the peat requires more water as it soaks. This may take up to 30 minutes depending on how much you have broken the brick up.
- Add in potting mix to a 70:30 ratio (potting mix:coir peat). Give this a good mix.
STEP 4: Potting your plants
- Plant the hanging pots before you attach these to the panel. One of the real breakthroughs in the Holman GreenWall system is that pots can be removed from the frame. This means that you can do your potting at a bench at a good working height.
- When you are ready to start planting, squeeze the bottom of the seedling containers to ease the seedlings out. Gently ease apart the bottom of the roots on each seedling. This will help the roots develop and grow into the soil.
- Put a handful of potting/coir mix into the GreenWall pot and place your seedling in. Top up with extra mix and press the plant in firmly.
STEP 5: Inserting the pots into the panels
- Place the pots into the panel. Each pot has a slot for a hook. Turn the pot to ‘lock’ it into position.
- If you are going to grow a mixture of plants in your GreenWall then it is worth noting that the top row is best for taller growing plants as their natural vertical habit of growth won’t be inhibited.
For the rows beneath, it’s better to choose plants with a trailing growth habit so these can get out from under the top pots to get access to sunlight.
STEP 6: Connecting water to the irrigation system
- Once the plants are in place connect a hose from a tap and click it into the hose connection.
- We suggest connecting the irrigation system of the GreenWall to a Holman Bluetooth Tap Timer. This will provide your plants with regular automatic watering.
- We recommend watering once a day for 1-2 minutes in cooler and 2-3 times a day for 1-2 minutes in warmer weather. Watering will vary depending on your plant selection and the location of your GreenWall. Everyone’s GreenWall conditions will differ in sun exposure, temperature and air flow so we recommend checking the soil moisture after the first few waterings and altering your watering schedule as necessary.
Coir peat aerates the soil and creates channels for water to travel through, watering the pots beneath. Regular potting mix that you would use in a garden bed may become to dense and block up the water channels inhibiting effective vertical watering.
Once growing on the module if something goes wrong, it’s easy to remove a single pot and sort the problem and even replant and then pop it back into its original position.
