With Spring around the corner, here is a list of gardening jobs to make the most of the warmer weather and growth ahead.

Cut flowers

  • Sow hardy annual seeds under cover in the greenhouse, windowsill, or under a light.
  • Wait until the middle of the month to sow half-hardy annuals for better light levels and warmer nights.
  • Sow perennials.
  • Pinch out tips of winter-sown sweet peas to encourage side-shoots.
  • Prepare flowerbed areas for direct sowing of hardy annuals in later March through April.
  • Mass prick out annual seedlings at the end of the month.
  • Transplant seedlings with true leaves into individual pots, handling them by the leaves.
  • Pot on rooted cuttings of tender perennial plants.
  • Take cuttings of perennials such as basal cuttings of phlox, delphiniums, and other early-sprouting perennials.

Garden Greens

  • Sow fruiting half-hardy vegetables like tomatoes before it's too late.
  • Indoors, sow courgettes, leeks, peas, beetroot, and cucumbers.
  • Sow perennial vegetable seeds such as globe artichokes and plant asparagus crowns.
  • Direct sow broad beans outside and cover the soil with plastic to dry it out.
  • Direct sow carrots, parsnips, and radishes after the soil has dried.
  • Plant early potatoes and one onion set or garlic clove per cell in a modular tray.
  • Grow potatoes and onions in a cool and bright location like a greenhouse until the roots show.
  • Thin carrot seedlings in the evening when carrot flies are fewer to promote decent-sized carrots.
  • Plant pea tips are great for a few fresh salad greens over the winter months.
  • Plant garlic, it will be a slow start but will shoot up in the spring.
  • Sow hardy peas under fleece to get ahead for the spring growing season.
  • Dig over your veg beds as the crops are finished. Cold weather can often break down any big clumps of soil, leaving good drainage ready for sowing.
  • Cover any productive salad plants like salad Rocket or perpetual spinach.
