Do you want lots of greenery but haven’t got the space? That’s a good reason to look up: a wall garden is especially suitable for small balconies and terraces. It is easily fixed to the wall and adorned with plants that are unaffected by being planted vertically. We’ll show you how to build a wall garden in a few simple steps.

Let's go - step by step

Step 1 13

Finding the right frame

Holzrahmen und Fenster.
First of all, you’ll need to find a frame that you like.

The first thing you need for your wall garden is a frame, which will be screwed behind the window later on. This is formed of a square outer frame with an intersection inside it made up of six wooden slats. The exact length of these slats depends on the dimensions of the window you’re using. The window we used measures 30 x 60 cm.

Step 2 13

Measuring out the slats

You can use a folding rule to measure the length of the slats to the precise millimetre.

It’s now time to measure the window so you can determine the length of the slats. Important: always place the folding rule in the centre of the window slats when measuring them as the frame will also be positioned here later so that it’s not visible from the front. You will need the following slats:

Square outer frame:
– 2x vertical slats that are the same length as the vertical outer measurement of the window frame up to the beginning of the window arch (see image)
– 2x horizontal slats that are the same length as the inner measurement between the two vertical slats mentioned above

Intersection:
– 1x horizontal slat that is the same length as the horizontal slats mentioned above
– 1x vertical slat that is the same length as the inner measurement of the bottom horizontal slat to the highest point of the window arch

Step 3 13

Sawing the slats

Mark out precisely where you have to saw and saw the wooden board at the marking.

Now, use a pencil to mark out the measured lengths on the two wooden slats and then use the AdvancedCut 50 to saw them accordingly into six slats. Make sure that the wood is firmly clamped to your workbench using G-clamps.

Step 4 13

Measuring the frame

It’s now time to mark where you’re going to drill the holes.

The next step will be to screw the frame together. For this, you’ll first need to join together all of the slats you’ve sawn to length – except the vertical slats for the intersection – to make the frame you want. Then, mark three drill holes in the middle of each of the two vertical slats of the frame – one halfway up the slat and two more on the left and right at the height of the opposite horizontal slats.

Step 5 13

Screwing the frame together

Next, drill holes in the marked positions on the slats.

Then, use the PSB 18 LI-2 Ergonomic and a 3-mm Brad point drill bit to drill a hole in each of the six marked positions. To screw the frame together, use the IXO and six wood screws (3.5 x 30 mm) to attach the vertical slats to the horizontal ones via the pre-drilled holes.

Step 6 13

Measuring the vertical slat

Holzrahmen und Bleistift.
Mark out the positions for the recesses with a pencil.

To complete the intersection, take the long vertical slat and position it in the centre of the frame. This is attached to the slat frame without screws by pushing it together using recesses in the two upper horizontal slats and the slat itself. To create the recesses, first mark the width of the long vertical slat in the centre of the frame’s two upper horizontal slats. Then, determine the depth of the recesses by marking half the width of the vertical slat, i.e. 2.5 cm, on both of the horizontal slats. Repeat this process on the vertical slat using the same dimensions of the two upper vertical slats.

Step 7 13

Sawing the vertical slat

Now, saw where you have made the markings.

Using the markings as a guide, saw out the recesses with the PST 18 LI. The vertical slat can then be pushed into the frame using the recesses. Tip: add some wood glue into the recesses before you insert the slat so that it’s more secure.

Step 8 13

Giving the veneer strip the correct dimensions

The next step is to make the veneer strip perfectly match your wooden frame.

Place the wooden frame on the rear side of the window. Then, hold the veneer strip for the round arch over the highest point of the protruding vertical slat to determine the required width and length. The width of the veneer strip must be equal to the depth of the wooden frame so that both are flush with each other. The length of the veneer strip needs to be shortened so that it can be attached at the height of the top horizontal slat. To do this, first make the markings.

Step 9 13

Attaching the veneer strip

Funierstreifen und Tacker
Attach the cut veneer strip to the horizontal slats.

Next, use the IXO universal cutting adapter to cut the veneer strip to the length and width needed, and then use the PTK 3.6 LI to attach it to the left and righthand side of the top horizontal slat and at the top at the protruding vertical slat.

Step 10 13

Back panel for the slat frame

Holzplatte und Tacker
Now, attach the plywood board to give your window a base.

It’s now time to add a back panel to the slat frame. To do this, lay the frame on the plywood board and transfer the measurements on to the board. Then, use the PST 18 LI to saw the back panel and use the PTK 3.6 LI to attach it to the slat frame..

Step 11 13

Attaching the mesh to the back panel

Draht und Fensterrahmen.
Next, adjust the mesh and cut it to size.

Lay the wire mesh on the back panel and cut it to size with the EasyPrune before then attaching it to the back panel with the PTK 3.6 LI. So that you can attach the wooden frame to the back of the window later, screw four metal brackets, each with two screws (3 x 14 mm), to all four corners of the window frame using the IXO and off-set angle adapter.

Step 12 13

Screwing the frame and the window together

It’s now time to join the frame and the window together.

You’re nearly done! Now, lay the frame on the back of the window and screw it to the metal brackets. If you’re planning to hang your wall garden later on, you then need to screw two flat connectors to the back panel of the frame using the IXO and four wood screws (3 x 14 mm). Screw one flat connector on in the centre at the highest point of the round arch and the other in the centre of the lowest horizontal slat.

Step 13 13

Filling your decorative window

Pflanzen und Fenster
You can now fill your window with soil and get planting.

The decorative window can now be filled with soil from above. A spoon handle is handy for pushing the soil through the wire mesh. Before planting your succulents, carefully uncover their roots. Then, use a wooden skewer to guide the roots through the wire mesh. To ensure that the plants remain in position even after the frame has been hung, you should leave the window in place for about two weeks beforehand as this will allow the roots to stabilise in the soil.
