PLASTIC

This is the most versatile material in terms of size, shape, design and colours available. There are now some really good-looking plastic pots, with a high quality look and finish.

Plastic containers are the lightest available, so are easy to move around and a good choice wherever weight is a consideration. They hold moisture well and don’t dry out quickly.

Cheaper plastic pots only tend to last for a few years, as sunlight and cold temperatures gradually degrade them and they become brittle and fragile. Look for thicker, betterquality ones for durability.

Thin plastics provide very little cold, frost and heat insulation. Light-coloured plastics heat up and cool down more slowly, so plant roots aren’t damaged as easily, even in sunny spots. Black and dark plastics heat up very quickly, so avoid using them in full sun.

Plastics are also mixed with other materials to increase and improve ranges even further. And many are designed and shaped to mimic other materials. Good quality ‘faux’ containers are often mistaken for the real thing.
