The idea of pallet gardening is basically to create a vertical growing space. We took a pallet and rearranged some of the slats into an orderly row. Then mypex was stapled tautly to the back. We flipped the pallet over and filled it with compost, and then planted lettuce and violas and ivy and nasturtium seeds in the gaps. We put bigger flowers like primroses and bulbs in the top, and sweet pea were to go in the lowest space, to climb up the rungs.
It's a nice idea and it's great to find a new way of maximising growing space. I think it would be brilliant for growing strawberries in particular. My only concerns would be the wall behind it getting very damp, and slugs living in the pallet.
In between numerous cups of tea and biscuits, we also planted up sundry containers - tins and china cups with holes drilled in them, a paint tub, a milk bottle - with marigolds and aubretia. We even filled hollowed-out tree stumps and a couple of holes in an apple tree with bedding plants.
All in all a great morning - mainly due to the lovely people we met there, and to finding a hidden gem of a garden in the middle of the city.
