Plastic drinks containers have long been utilised as pots by innovative gardeners.
Another trick is to cut them into long strips that double up as plant labels.
Large plastic bottles with their base removed can be placed over individual brassica plants to deter pests and encourage initial growth.
Several schools have made ‘greenhouses’ from such bottles. Nor is it unusual to find a vegetable plot glistening with CDs suspended on strings as a pigeon deterrent.
Expensive containers for plants are shunned by canny gardeners who stack a few car tyres, plant up old boots, kitchen sinks, even loos. And why buy an expensive raised bed in which to grow vegetables or herbs, when a few wooden planks knocked together will suffice.
