Grey Pots

Drainage is essential for healthy plants. If you have a pot without holes in the bottom, you should invest in an inner pot – a smaller plastic flowerpot with holes in the bottom. This allows the water to flow through, so the roots don’t rot.

Garden Patch has tips on how to choose the right size of pot, which is also important for the well-being of the roots.

• Terracotta: Terracotta is an organic material that breathes and absorbs moisture. This improves oxygen supply to the roots, so it can be a good choice if you know you have a tendency to over-water. Terracotta pots also develop a charming patina over time.

• Plastic: Will your pots be standing outdoors? Plastic is an insulating material that protects against both heat and cold. Plastic pots don’t absorb moisture from the soil like terracotta pots do, so hydrangeas, peace lilies and other thirsty plants thrive best in plastic pots. Plastic is also lightweight, which makes it a good choice if the pot will be standing an indoor shelf.

• Glass: The roots of some plants, such as orchids, prefer plenty of light. Give them a glass pot and they will thank you with beautiful flowers. But keep them away from direct sunlight, as the glass can easily get hot.
