Scorched maple leaves

[Fred1991]

Hi all! Are these laves sun scorched (i don't normally keep it in full sun)? or water shorage scorched? oor myabe my water is to acidic (i live in london with hardwater, i've started collecting rainwater now tho) Any tips to getting healthier foliage?

You could try defoliating. Scorched leaves feel almost brittle with little softness and no firmness.

I defoliated my leaves that got burned late june and they just started coming back much healthier than the first set.

Not sure if this is the case but i think i learned that unhealthy leaves taxes the maple more than no leaves, but to only defoliate healthy trees. Always some risk involved but best to do it with knowledge and understanding.

I kept my defoliated tree under constant shade and sparsely watered. It took about 3 weeks or less before the leaves budded

Looks like a day or two with not enough water, or maybe drying wind. Japanese maple leaves can be delicate. What I often do in this case is partial defoliation, or just some leaf cutting (cut off 2/3). Enough leaf cutting will stimulate more budding, you'll have to do it to most of the tree.

Thanks for your reply Erich! I believe it’s from under watering aswell. I might leave it like this till next year as I have recently done a partial defoliation and I don’t want to stress the tree more than necessary. What do you think?
