Spray nectarine and peach trees to prevent peach leaf curl disease.

Sow quick-growing perennials under glass to flower this year.

Sow long-rooted parsnips as soon as possible, as they benefit from a long growing season.

Harden off autumn-sown cauliflowers being overwintered in frames, so they will be ready for planting out in March.

Continue to keep hippeastrums moist and feed them occasionally.

Plant begonia tubers in pots of soilless potting compost. Keep the tubers just damp until the first shoots begin to show.

Continue to plant fruit trees and bushes if soil conditions allow.
