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 on east coast and wondered whether it is a good idea to plant lettuce seeds and what type for summer 2020/2021?

The open leaf varieties. Cos, butter crunch, oak leaf etc. Lettuce seedlings take a lot of care to grow. Seeds need to to be very close to the surface to germinate, only a couple of mm of fine potting mix or seed raising mixture to cover them. Water with a sprayer or mister not with a hose. Water 2-3 times a day, keep the soil moist. Will need to grow them for 3-4 weeks before transplanting them.

When you cut lettuce dry it out before putting in a bag and into the fridge. A spinning colander is best.

I am trying to grow lettuce in soil I have added my home compost to. All seedlings get nibbled down to nothing at night and I can't identify what is going it. I live in Perth and very keen to know what is doing it and how I can control them

Go out at night and see what is eating the seedlings. Sparrows eat my lettuce the first couple of months of the year. I have a bird trap now. They also eat the heart out of my snow peas certain times of the year. Work out how to put a border around each plant or the whole block of lettuce. Like a 90mm pipe 100mm long and put oil or grease or Vaseline on the outside. Or look up similar things on the internet for slugs, snails etc. Or build a frame and cover with shade cloth.

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. .
