Will my Japanese maples recover, or did I killed them?:(
Last year I planted 3 beautiful Japanese maple trees (Acer palmatum). I spoted some caterpillars, which were eating tree leaves, so I used an insecticide, which uses permethrin as active ingredient. Insecticide is more for indoor use, but some are using it outdoors, i made a mistake.
Result: disaster, tree leaves are turning yellow and seem like they do not have any water in it and are burned.I used it a few days ago. Today I washed each tree 3 times with water from garden hose and put some Activated Charcoal on the ground.
The trees are about 50 cm high (1,64 feet).
What do you think, did I killed them, or will they recover? Wil new leaves grow or do I stand the chance in next season? What can I do? I am so sad. If tree leaves do not recover, then probably trees are dead.
