Yes you can, but depending on how hot it gets where you are, you should choose a heat-tolerant variety or it will bolt too quickly. I recommend the red varieties of summer crisp Batavian lettuce. You should be able to get them at Swallowtail Gardens online if they haven't sold out for the season.

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.

Hi I punnet my lettuce but the turn colour the next day. They start getting brown especially when I cut my lettuce on a rainy day and pack them. What I'm i doing wrong ?

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.

When is the optimal time to grow romaine lettuce in 9B, Ocala,Fl

I grew romaine last year in the Phoenix Valley (9B). I think I waited until December to sow the seeds. We got a really nice crop of it... but last winter it seemed to last much longer than normal, it was still very chilly in Feb. last year (low 60's), when generally we get into the mid 70's then. You could try starting indoors.

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
