  • Space plants: 8 - 12 inches apart
  • Harvest in 8-12 weeks.
  • Compatible with (can grow beside): Carrots, Onions, Strawberries, Beets, Brassicas, Radish, Marigold, Borage, Chervil, Florence fennel, leeks.
  • Avoid growing close to: Parsley, Celery
  • Lettuce seedlings
  • Lettuce table-ready

Lettuce offer a range of shapes, sizes and colours but they are all easy to grow. Choose a variety marked on the seed packet as suitable for the time of year as some do badly in the very hot months. Try to provide some shade to prevent them 'bolting' to flower and seed in the hottest months.

Sow in rows and use thinnings as small salad greens

Lettuce are shallow rooted so water daily in hot or dry weather to prevent bitter flavour. and bolting.

Culinary hints - cooking and eating Lettuce

Wash well, spin or shake dry and use in salads and sandwiches

I live in Northland and have moved from the UK so am lacking experience in what grows well in this warm climate. I struggled to grow salads through the summer last year. Which varieties of lettuce grow/stand better through hot weather without so much tendency to go bitter or bolt? Thanks, Libby

I'm Australian sub tropical and if you are similar weather then we mainly grow things from March into winter and some things from late winter into spring/early summer. Most of what you read in Australia and probably NZ applies to temperate and colder climates. They all talk about planting after the last frost. Where I live we generally don't have frosts. Never had one in my yard in 40 years. Things don't grow much here in July August otherwise can grow things most of the year. Summer hot and requires a lot of watering and attention and only certain things will grow. I rest my ground in summer.

As it says here read the packet for when to plant. Generally the open (not heading) type are better for summer, butter head or butter crunch etc. Try and provide some shade during the day, in the sun in the morning in the shade in the afternoon or shade cloth frame. .

I have found it best to raise seedlings and plant lettuces and similar salad crops on the East side of house below the eaves. They get early morning sun until about 11am and then they are in shade or indirect sun. Everything thrives. I just recently put green shadecloth around raised garden be for the same reason as last year everything dried out too easily and required daily soaking. in the present drought I think I might be ok with these two precautions for spring-summer crops.

Hi I'm totally new to any kind of growing and am currently experimenting with a hydroponic setup But having trouble getting lettuce seeds started. Had no problems with previous 3 attempts but this time the seeds are doing nothing. Not sure if its the time of year or something else........ Any advice would be appreciated GD

Wait until this present cold weather passes and we have warmer nights. With spring only a week or two away temps should start to rise a bit, then try again. Lettuce need light to germinate. Keep soil moist and use a fine light watering.

Hi Karen, I recently bought Butter lettuce seeds from my local Bunnings! And have had great crops right through winter, just direct sew into garden and pick young leaves to thin them out. I'm in Perth. Regards Nicole

It is called buttercrunch lettuce. Try BOONDIE seeds on the internet.
