What can I plant in April?
(UK Gardening Guide)

April is when the UK vegetable garden really starts to move. Soils warm up, growth speeds up and you can sow a wide range of hardy crops outdoors while starting tender summer vegetables under cover. Late cold snaps are still possible, so a little protection keeps early sowings on track.

What can you sow in April?

April is a great month to build momentum. You can direct sow hardy vegetables outside once the soil is workable, and you can start tender crops indoors for planting out later in spring.

If your soil is cold or heavy, warm it with cloches or fleece and avoid sowing when the ground is waterlogged. Seeds sown into chilly, wet soil often struggle.

Successional sowing (small sowings every couple of weeks) helps spread harvests through summer.

April gardening tips and common mistakes

April can feel like the perfect moment to plant everything, but UK weather can still swing between warm days and cold nights. These simple checks help you avoid setbacks.

  • Sproutly Gardening logoSowing into cold, wet soil
    If the soil is sticky or waterlogged, wait. Use cloches or fleece to warm beds instead of rushing.
  • Sproutly Gardening logoPlanting tender crops out too early
    Courgettes, squash and tomatoes should stay under cover until after the last frosts and mild nights.
  • Sproutly Gardening logoForgetting to thin seedlings
    Carrots, beetroot and salads need space. Thin little and often so plants can size up properly.
  • Sproutly Gardening logoLetting weeds get established
    Weeds grow quickly in spring. Hoe on dry days so weeds dry out and do not re-root.
  • Sproutly Gardening logoIgnoring late frosts
    Frost can still happen in April. Protect early potatoes and new seedlings with fleece overnight.

Sproutly Gardening tip: Add reminders for frost forecasts, watering checks and thinning, so April’s fast growth stays manageable.
