Shin deshojo with leads burn help

[ShadyBonsai]

Hello my shin deshojo recently just went through a bad leaf burn, possibly my fault we got some extreme heat and I watered in the sun, next day the leaves were all degraded, not sure the best way to care for it now I had been planning to air layer a branch or two but maybe I should put that off? Any suggestions would be helpful thanks

Probably just too much heat and intense sun for too long each day? Watering in the sun isn't actually an issue in the burn department. Could be for fungus. I'm in Seattle and was watering all my trees in the middle of the day in the 90 degrees yard. If you lost a lot of foliage, then yeah, you might want to wait on layering until it comes back strong. You should probably stick your tree in dappled light to let it recover as well, though we're headed back to highs in the 60s again soon so maybe not an issue.

I'm in the notoriously un-sunny UK and get some pretty bad leaf burn on my maples, particularly my deshojo. I've found the best place for it is in a nice shady spot, it gets a couple of hours of full sun at the minute (late spring) but I might even need to move it to a fully shaded spot.

Luckily they're strong and should come back well with a little TLC.

Watering in the sun does not cause leaf burn. That's a myth.
Drying out in hot weather does cause leaf burn and beginners often don't check well enough or water thoroughly enough to maintain enough water in the soil to get a tree through a hot day.
In addition, Japanese maples do not cope well with hot sun. They are adapted to cool, damp valleys so some shade in hot weather is a must to keep leaves in good condition. Need to learn how your soil mix copes with watering and water retention and modify watering schedules to make sure there's always enough moisture in the soil.

There's not much point trying to layer a tree with few or no leaves to help grow new roots. I'd defer the layering until your tree has recovered and you can get on top of care during hot weather or you risk losing the tree as well as any layers.
