The flower garden
Sow hardy annuals, such as love-in-a-mist and pot marigolds, as well as native wildflowers, into gaps in borders
Continue deadheading spring bulbs and bedding, so they don't waste energy setting seed
Sow sweet peas at the base of supports, and transplant those sown in autumn into their final positions
The veg patch
Plant second-early and maincrop potatoes
Sow flowering companions in the veg plot, such as pot marigolds and borage
Sow outdoor varieties of tomatoes, chillies and courgettes in pots, so they're ready to plant out in late May or Junes
Green gardening
Protect the new shoots of hostas, delphiniums, lupins and other vulnerable plants from slugs and snails
Pinch out the tips of broad beans if they're covered in aphids, or spray shoots with soap-based solution
