How to: Grow Iceberg Lettuce

Iceberg lettuce is easy to grow, either in a raised bed or straight into your garden. You can pick up seeds now which you’ll be able sow under cover this month or outside in a few weeks time. You can also plant young plants from March, to give your crop a head start.


If you don’t want to wait that long, salad leaves come in many quick growing varities that are ideal for windowsills, perfect if you’re new to growing your own or if you want leaves in just a few days time.

You'll need:

Follow these easy steps to grow your own iceberg lettuce:

  1. Choose a sunny spot for your lettuce and make sure your soil is free of weeds by raking it until it’s fine and crumbly – remember to pick out any large stones.
  2. Tie a piece of string to two sticks and use it to create a straight line on the surface of the soil.
  3. Along the length of the string – use a dibber or your finger to plant the seeds half an inch deep.
  4. Sprinkle a few seeds along the length of the string with a 12 inch gap, so you space it evenly giving it enough room to grow.
  5. Remove the line of string and carefully cover the seed with soil. Add a label at one end of the line as a reminder of what you’ve planted.
  6. Water the seed well and wait for the seedlings to appear.
  7. Over the next one – two weeks remove the seedlings that look weak, leaving the strongest in position, you can still use the ‘thinnings’ as baby leaves though.
  8. Enjoy your first harvest in June – it’s as easy as that.

If you’ve opted for young plants, you can still follow these steps but there’s no need to cover with soil or thin out, just use compost to push your seedling into place.
