WeWe planted the tree about 2 months ago. It was thriving beautifully. Last week suddenly the leaves curled up and dried becoming brown. It coincided with dry days (I’m in northeast) so I started watering it every day but so far it hasn’t recovered. The main stem and branches look,healthy and their tips are still green. I tried to give it plant food but noticed no difference. My neighbor suggested it may have used up all the good soil from the pot where it came and now it is facing the clay soil in my house. Is it possible? Is it dying? Any suggestions? Thanks.
