Growing in Containers

Many big or small fruit and vegetables will grow well in containers; anything from carrots to cucumbers and flowers to dwarf fruit trees. The trick is to experiment to see what grows best and always look after them.  The confined space of a container means that plants depend on you for watering and feeding.

Choosing containers 

Getting the best container size Choose containers as deep and wide as possible, but still practical to fill with ‘growing medium’ and move when they’re full. Smaller containers tend to dry out quickly and are less suitable for big plants as they limit root growth. 

Choosing container materials

Try any new, reclaimed, or recycled material that is sturdy enough to hold the growing medium. Make sure it’s frost proof and not contaminated with chemical residues, eg avoid tyres. Good options include wooden half barrels, old buckets; large plastic and terracotta pots; window boxes; and so on. Use your imagination!

Ensure good drainage

Drainage is critical. Water will otherwise collect at the bottom of a container and saturate the soil. The roots may then rot and the plants die. Add 1-2cm wide drainage holes if the container doesn’t have any (at least five per 30cm2). Improve drainage by putting a 5-10cm layer of broken pots, gravel or grit at the bottom of the container. Broken-up polystyrene is a lightweight alternative and good recycling. Standing containers on ‘feet’ to lift them off the ground also improves drainage (bought or made from bricks).
