How do I grow basil in a raised bed?

Sow or plant into warm, moist mix in the sunniest spot you have. Pinch out the growing tips regularly to keep plants bushy and stop them running to flower.

How often should I water and feed basil?

Keep the mix evenly moist — basil wilts fast when dry but hates soggy feet. Water the soil, not the leaves, in the morning.

What pests attack basil?

Keep an eye out for aphids, whiteflies, slugs and snails and caterpillars. Most are easily managed — see our safe pest guide.

What diseases affect basil?

The main ones are downy mildew, fusarium wilt and damping-off. Good airflow, morning watering and steady moisture prevent most.

What grows well with basil?

Basil and tomatoes are the classic pairing — plant it right alongside your tomatoes and capsicums. See our companion planting guide.

When do I harvest basil?

Pick leaves from the top down and often; regular harvesting keeps it producing. It doesn't store well, so use it fresh, freeze it, or make pesto.
