You will need
A pallet (ours was 120cm /47 inches wide by 80cm /31 inches high)Geotextile membrane
2 x compost bags (we used size 40 litres)
Plants
Wood offcuts
2 x screw in metal eye hooks
Electrical ties
Tools: Staple gun, small saw, scissors or knife.
Instructions
1. Improve the appearance of your pallet if needed. Ours came from my in-laws and didn't need sanding but needed darkening with one coat of fence paint.
2. Lay the pallet on its front. Slide the unopened compost bags into each half of the pallet.
3. Secure in place using geotextile membrane and a staple gun.
4. Turn the pallet over.
5. With the pallet horizontal make rectangular cuts in the gaps between the planks with a knife or scissors.
6. Add plants to the gaps but allow room for growth. Work from the top down and leave the bottom row empty to allow for trailing space (we left too much space at the top in hindsight so ignore the photo). We chose nasturtiums, lobelia, trailing tomatoes, French beans and thyme.
7. Leave the planter horizontal for 1-2 weeks and water daily.
8. Gradually make the planter vertical over a week to 10 days. We used our garden table to prop it up at different angles. Move it carefully to ensure the compost bags don't slip out.
9. Secure the pallet to the fence with screw in metal eye hooks and electrical ties (you could also use chain wire or rope).
10. Stand the pallet on small blocks made from wood offcuts so that the surface underneath has chance to dry out after watering.
11. Once the pallet is vertical cut open the top of the compost bags and add more plants.
12. Water daily if possible even if it rains!
13. Finally enjoy your colourful and bee friendly planter.
