I live in Sydney and find that you got to keep the water up to them. Now find that growing mixed lettuces in a tray in semi-shade seems better as their roots aren't deep and they don't wilt. I use the deepest "kitty litter" tray and punch some holes in them and line them with old leaves before proceeding with my soil mix. Use weak solution of seasol once a week on them and and fresh water on other days.

Can I just harvest leaves from my mixed lettuces or do I have to uproot them and sow more seed...??

If it is the coral type of lettuce and not iceberg (those with a firm heart) then you can pick the outer leaves and it will keep producing until time to bolt (seed)

My wonderful 80 odd yr old neighbour gave me this tip and works really well. When washing your lettice add salt to the water and snalls ect leave much quicker. Its surprising whats left in the water after doing this.

I have planted some crops (based on your advice) and was wondering what is eating at my dwarf cos lettuce and rocket ? I see no evidence of grubs or snails. Can you please help ?

Might be mice/rats. My iceberg seems to be eaten by these. Or do you have rabbits in the area?

When you say your lettuce didn't make it, did it bolt? or not grow at all?, you might need to check your soil PH as lettuce is quite easy to grow....... there is no chance of every starting too big, I wish my vegie garden was double the size. I would check your soil and make sure that you don't under or over water.

All my latest cos lettuces growth seemed to be stunted. It was a very hot day the day after planting and they looked sick, but 3 weeks on and still very little growth even though they've had a fertilising.

Maybe try sowing some more seeds now, it was fairly hot earlier in the month. It likes 10-16C.

I've planted a number of lettuce types and all have grown well, and we've had a few meals from them, until we hit a heat wave recently, 7 days of over 35 degree heat. Now, I've just found out that lettuce goes bitter or bolts in the heat, which is what all varieties have done. Is there anything I can do to save it, or should I just feed it to the chooks and try again?

Gardenate is a 'guide' not hard and fast rules. Your microclimate obviously suits cos lettuce. By the way, we have not included inforamtion for the Caribbean because we do not have enough information about the climate.
