How To Plant And Grow Your Own Onions

Tom Cole from Capel Manor College in London shows you how to plant onions from seed. Learn basic gardening tips and grow some great onions in your garden.

Step 1: You will need

  • Seeds
  • A garden hoe
  • A cane or something similar
  • A plank of wood
  • A frame and horticultural fleece
  • A garden fork
  • A metal rake
  • A stake and string
  • A landscape rake
  • It is also useful to have plant labels

Step 2: Prepare the site

Onions should be planted in sunny or partially shaded sites that are sheltered from the wind. Loosen the soil with a fork and remove any weeds or large stones. Use a rake to create a level surface. If you have poor soil you may want to add well-rotted organic matter before you start sowing.
Use the head of the rake to lightly press down the soil and lightly rake the surface once more.

Step 3: Plant

Onions should be planted in shallow rows called 'drills'. Lay a piece of string on the soil as a guide to make sure you dig the row in a straight line. Lay a plank of wood next to your line. Then, use a cane or hoe to dig a narrow drill about 1 centimetre deep.
Drop the seeds into the drills at the spacing recommended on the packet. If you are planting more than one drill, leave a 30 centimetre gap between each one. Using a hoe, gently cover the seeds with soil. Then using the head of the metal rake, lightly firm the soil.

Step 4: Water

If the soil is dry, water the seeds in. The soil should be kept moist and free of weeds throughout the growing season. It is also useful to label your onions so you know where and when they were planted.

Step 5: Protect

To protect your plants from late frosts in Spring, build a frame to cover the drills. Push the sides of the fabric into the soil, or fix it in place with canes. Remove the fleece when the seeds germinate and the plants are visible through the soil.
