Even my sweet basil is bolting for the first time ever. The weather has been kind of funny though. We're meant to be having tons of rain this season but... not quite.yes you get extremes in the heat although the bronze is heat tolerant even your highs there you would see bolting if you try to grow them for max size so cut them back when a good size and let them regrow , and planting so it mature at the coolest point of growing season and shade it or plant it in a well shaded area as best as possible. but sadly most lettuce and cole crops wont fair well in the extreme heat.
for hot areas try one of these romaine -
"Jericho," developed in Israel
"Anuenue," a romaine developed in Hawaii-
another good choice for those crackling temperatures. "Craquerelle du Midi," an open-hearted French variety,
there are numerous loose leaf that do well in higher heat and a few of the crisps heads variants, the major issue you will find with many lettuces once you start exceeding 80f ( 27 c ) they tend to start taking on a bitter taste i have had exceptional luck in the butter head type like buttercrunch and the Mignonette bronze tend to fair very good in heat and still keep a milder flavor doing basically a cut and come harvest snipping off leafs when still young and letting them regrow for best result before they do bolt. we have had summers here of high 80 to mid 90s same range as you but not as prolonged and romains and butterhead types have dne well fr me as have some loose leaf types grown with shade over them oak leaf and Royal Oak Leaf - Black-Seeded Simpson
The ultimate if you have some space would be hydroponics as i do indoors here is that same Mignonette bronze from yesterday post and today , you can see the growth , this is a slower lettuce to starts but once it starts growing it moves along at a consistent steady growth. deep water totes like some i show in photo in an area 18 x 48inches ( 46 x 122 cm ) i can grow and harvest cut and *** year round easily growing up to 30 heads in that amount of space attached a couple photos of what a simple area that size can grow
second photo was returning from a week away and no one to tend and returned to an overgrow 18 x 48 lettuce area with 28 plants growing as a jungle.
3rd is another time of year same area with herbs growing before i set up a more permanent place for herbs and yes i had massive bumper crop of a wide variety of basils
I've found that parsley and chives grow amazing here and I can practically ignore them. They'll even live when I forget to water them and whatnot. I'm now seeing my oregano, lemon balm and mint show similar behaviour too.
I'll have a look at those lettuces! I did indeed have issues with bitter tasting lettuce. Might be best to keep that coming from a supermarket perhaps.
