Lorraine in 100 degree California heat asked:
<My question is: how did you handle the sun on these happy plants on
the first few days of full "hot" sun? >
The short answer to <how did I handle> the negative effects of abrupt
exposure to direct sun & heat is <with respect at the funerals> <g> I
don't sell irises, don't do much trading, & am obsessed with getting a
collection of only the very toughest TBs for my growing conditions.
The longer answer - I waited till it was in the 'cool' 80s to start
excavating irises from the weeds, thinking we were out of the 90s for
the year, then temps went back into the upper 90s and some of the newly
exposed irises did get sun/heat damage on some of the foliage. They
bleached a bit. But once temps settled into the 80s more consistently,
& I was able to get back to chopping out the jungle, they were fine.
Keep in mind that I am merciless about getting rid of cultivars that
can't take the humidity/rain and heat, so those that get soft rot (damp
off), in those conditions are welcome to die.
With all the rain, a few of the newly planted cultivars have lost a leaf
or two, rotting off at the base, but most are fine. In spite of
torturing seedlings ahead of time, two or three of the 100 or so, still
fairly small, seedlings from this spring that I've lined out recently
have died.
I should add that, except for a small area of quack grass (or is it crab
grass??) all of these weeds are single stalked, tall, with most of the
foliage up above the ground. Even the foxtail millet is tall and leafy
above the ground, until it gets knocked down and matted. Dense grasses
and clover are bad news - most irises definitely don't thrive with those
as <companion plants>. I do try to keep them completely eliminated from
the iris rows.
Forecast sounds like we are going to be swimming by the weekend!
