Jump-start on salads
Try to get lettuce seeds in before it gets too hot. There are some interesting combos available that'll give you a blend of salad leaves. Sow seeds every few weeks to ensure a constant supply.
Give ornamental plants a spring clean-up spray to deal to rust, black spot, insect pests and mites.
Broad bean flowers should start to form pods as temperatures warm up. Pick pods when they're young and throw a few flowers into your salads.
When flower buds start to develop on roses apply a light dressing of sulphate of potash. Its role is to harden spring growth and provide substance and colour to the bloom.
