How to plant shallots in March

Shallots are a reliable, easy-to-grow crop that produce clusters of small, flavourful bulbs. Planting in March gives them a long growing season, helping them establish strong roots and develop well-sized bulbs by summer.

They are ideal for beginners and perform well in most garden spaces.

Quick answer: how to plant shallots

To plant shallots, push sets into well-drained soil with the tip just showing above the surface, space them evenly, and grow in a sunny position. Keep the soil lightly moist and weed-free as they establish.

Step-by-step guide to planting shallots

Step 1: Choose the right location

  • Select a sunny, open position
  • Ensure well-drained soil
  • Avoid heavy, waterlogged areas

Step 2: Prepare the soil

  • Loosen soil to around 15–20cm depth
  • Remove weeds and stones
  • Rake to a fine, level surface

Step 3: Plant the sets

  • Push sets into the soil so the tip is just visible
  • Space 15–20cm apart
  • Space rows around 30cm apart

Step 4: Firm and water lightly

  • Gently firm soil around each set
  • Water lightly after planting
  • Avoid overwatering

Step 5: Maintain and protect

  • Keep the area weed-free
  • Protect from birds lifting sets
  • Water during prolonged dry periods

When to plant shallots

Shallots are best planted:

  • In March for spring planting
  • When soil is workable and not frozen
