I live in zone 8 and planted a dogwood sapling back in December. It sprouted many leaves this spring and was doing well. About a week ago, I noticed a few leaves turning brown on the edges and suspected leaf scorch. It only gets about an hour of full sun a day on my balcony, but I immediately moved it inside to try and remedy it. I water it thoroughly when dry, so I don't think that under-watering is an issue. Anyway, so just yesterday, I noticed that all of the leaves are drooping and turning brown. Even the tips of the branches are darkening. What can I do to save my tree?
I've attached images. Thank you for advice!
