90s F And 10-20 mph Winds - A Recipe….

Schefflera and Gingko damage from the heat and winds here in southern CA.
Trying to figure out if the burnt schefflera stem is directly from the sun or from wet soil media that warmed up and cooked off roots.
The schefflera was just worked hard about 2 weeks ago. The shallower ginkgo pot dried out quicker than the others and newer spring growth wasn't ready for the heat.

All I had to do was move them 8 feet away. Thought they would have been fine. They were watered and misted. Live and you learn……

That sucks . Zone 4 Canada I don’t have trees cooking in the spring . I’m curious about your thoughts that the heat cooked the roots . Would the water in soil and the misting not help
. Plus the wind I understand drying the foliage but would it not also cool the pot at least from evaporation . Not saying your wrong just trying to learn in my climate small pots warming up is a advantage until mid summer heat at least

Had some pre made arrangements at work a little bit ago. They were a small pretty 3 foot pittosporum with stuff planted around the base. It got hot (not this time) and people kept watering. Had a bunch of returns with fried roots that killed trees. Essentially they had plenty of water ….then that water heated up in a ceramic container.

On the fried stem, it just had hard work done and I opened up the interior getting sun to trunk (new buds) that was likley previously unexposed to full sun.…..I think. High 60s low 70s F then bam 90 F with hot dry winds.

Wind is a killer . Up here I winter my trees in a un heated building . Learned the hard way even trees cold hardy to colder conditions . Can’t withstand wind when there roots are froze . Winter to a tree is just a dry time wind is the killer

Doesn't really look like desiccation to me. Hot winds would start by drying the margins of leaves and work their way inward... not start at the middle of the leaf and work outwards. I would be worried about fungus, particularly with the black stem - which shows the middle of the stem dying while the sections above and below look healthier.

The burnt limb continued to dry and shrink in diameter and I pruned it off to the next bud.
