Autumn moon maple
Anything wrong ith my autumn moon. I'm seeing brown burn spots on leaves. It's been very hot in easten pa. And has been raining alot.
Maple is still in potting soil I bought it in but it is in screened al gritty mix. I have been watering about once a week or when wood skewer is dry.
Maple is under a tree canopy getting alittle dircet sun in morning and alittle direct sun after 430 pm.
I just started 2 weeks ago 1/4 tsp of dyno grow once a week making sure I water where original soil is from pot. Any ideas. Is it heat stress, over/under watering. Fert burn?
Any help would be great.
