Most plant do terrible in very hot weather. (Unless youre cactus.)
Zuchinis cucumbers and plants which are susceptible in highly humid
conditions get what some loosely call blossom end rot.
The reality is, heat slows/stops/kills some plants. Deserts are better
in that deserts are dry. This means air doesnt conduct heat as well.
I found it difficult to get lettuce plants in December January, until
accountants started asking why they weren't selling any at that time of
year.
So youre finding out The reason was most gardeners had problems
growing them is stressfull heat.. (Melbourne)
If you plant them amongst other plants, you can do like me, have success
if you water them twice a day, and keep checking them fro heat stress..
No problems in NE Victoria. if you are aware that Aquasol is helpful,
but if they get limp, like most they cannot reproduce or even grow.
A bit like humans really. When your hot , youre not...

The first couple of batches of lettuce did fine, First batch was mignonettes,
planted from seedlings from bunnings, transplanted early sep, took a bit of
time to start but then did fine. Second batch was cos, planted mid oct
from seedlings from bunnings again.

They both went to seed after a very hot spell in mid Nov, got quite a few leaves to eat until then.

I've since planted some more icebers, 'salad mix', cos, and lollo rossa, mostly
from seedings from bunnings, but the salad mix from someone flogging them
at the sunday market.

None of them have done much except the icebergs.
They havent died, just havent done much growth wise.

The icebergs did grow noticeably, up to big bigger than a large grapefruit size,
but no hearts. Since the first two batches had gone to seed I did start using
leaves off the small icebergs. Now even the icebergs seen to have stopped.

We have had much hotter weather obviously, in fact a couple of patches
of a week or so over 40C, with some rather cooler times in between.

They get plenty of water, once a day from one of those
soaker hoses that sort of weep water rather than spray it.

Is it just that they dont like the very hot weather ?

The net seems to suggest that thats the problem.

Are there any varietys that do much better in the very hot weather ?

Dunno, my tomatoes and potatos and strawberrys are doing fine.

Mine isnt highly humid, in fact we normally have
single digit relative humiditys on the hottest days.

The reality is, heat slows/stops/kills some plants. Deserts are better
in that deserts are dry. This means air doesnt conduct heat as well.

You wanna try hot windy days when the temp is 45C.

selling any at that time of year.

Why arent they eating salads ? I certainly do, more than in winter etc.

I've just started doing that now, be interesting to see what difference it makes.

Nothing visible with the previous ones, they just dont do anything, dont grow.

No problems in NE Victoria.

Thats a similar climate to mine.

if you are aware that Aquasol is helpful,

Havent been fertilizing them, mainly because the first two
batches of mignonettes and cos in spring did fine without any.
This is on fresh ground that has just had weeds growing on it.
I did apply the Brunnings vegitable starter fertilizer before
transplanting the seedlings with the mignonettes and cos
but not with the later 4 batches of mignonettes and cos, salad mix
and icebergs. I've just applied some now to see if thats the
problem. The strawberrys in that patch are doing fine tho.

but if they get limp, like most they cannot reproduce or even grow.

Yeah, thats why I transplanted another punnet of the Lettuce Combo,
tho the green flat leaved seedlings have produced new leaves. I didnt
ask the woman at the nursury which particular ones she was getting
the new leaves off, she wasnt there yesterday when I got the
second punnet of Lettuce Combo, I'll show up on Thursday and
see if she's in there again.

A bit like humans really. When your hot , youre not...

Most of the tomatoes are doing fine, particularly the
Cherry Sweet Bites, Father Toms and Mama's Delight.

The problem appears to be that lettuce doesnt like stinking hot weather much.

Those plants like hot weather and have small leaves.
All large leaved varieties seem to go limp when the wind hits them EG
Rhubarb, Silverbeet Lettuce Pumpkins.
Wind screws them up badly. The wind and heat evaporates moisture and the
roots cant keep up...
My patch is muddy at the moment (Luck so far no water restrictions) Must
put the timer on for shorter periods...
All you in water restricted areas, due to government mismanagement (No
Dams Etc) suffer! (grin!)
Most lettuce plants like Mignonette are spring type plants.

You wanna try hot windy days when the temp is 45C. (grin that exactly what were getting)

Yep but theyre hard to grow, so they shouldnt sell the plants then.
growing them at that time can mean failure.

If you plant them amongst other plants,

I am doing that.

They must get some direct light, as otherwise they grow a bit funny.
(though comic vegetables would be a change from the usual.)
you can do like me, have success if you water them twice a day,

if you are aware that Aquasol is helpful,

The growing instructions say grow them fast. Magnesium Suphate or Epson
salts appear to help greatly in the plants, depending on your soil, but
I've found it beneficial in most cases.

These liek hot weather. The trick is to find heat resistant types,
allthough I like the Great Lakes lettuces, (not happy but still growing
OK) and let my wife grow the mignonette variety.
Theyre more of a soft leaf type, and I like the crisp types. The
mignonettes seem to like spring time best.
The problem appears to be that lettuce doesnt like stinking hot weather much.



This seems to answer most questions well!
