stackable pot MATERIAL Manufactured from tough polypropylene, the 20cm deep 3 layers of anthracite-coloured pots provide up to 1 metre of growing height and each tier contains almost 34 litres of compost, giving strawberries, herbs, salads, bedding plants or foliage plants plenty of room to stretch out their roots. EFFICIENT DESIGN The dark colour of the stackable garden planter pots attracts heat and helps the compost warm up and when you consider other vertical growing benefits such as decreased soil pest and slug action, ease of maintenance and potential location by the kitchen window or door for dew-drop fresh harvesting, it’s clear that height does have the advantage!

Visually pleasing from all angles. WATER-CONSCIOUS Two drainage ports, raised about 3 cm off the bottom of each pot,
