My shed is overflowing with polystyrene cartons.
Large ones, used by my meat supplier to ship deliveries. I have, for some time, been pondering what to do with them. The local binnies are reluctant to take them. Unless I break them up, which is messy, and disguise them in black bin bags.
So I have decided to re-purpose them. They are going to become planters. We are going to use them for both floral and veggie planting.
Phase one is to coat the exterior with masonry paint. I have chosen battleship grey, as a nice neutral colour, which will provide a good backdrop for the plants.
My thoughts are that the planters will be light enough for me to move around on a whim. The polystyrene will provide a thermal barrier, keeping the plant roots warm.
I might even try some other colours and possibly textures / patterns as my confidence grows.
I’ll post more pictures as the planters are utilised.
