Seedling
I know my question is quite simmilar to the previous tread but as each case is different I thought I would start anew.
As you can see in the photos I have some kind of burn going on with this tree. I've read through as many posts as I could find pertaining to scorched or burnt leaves and I really haven't discovered a reasonable course of action.
First is it sun, water, or roots?
The onset of this has been taking place over the last few weeks. Leaf tips turn black then begin to brown. I've lost some whole branch tips but only a few. Last week I cut back some overly long branches near the apex, removed some large leaves and some of the burnt ones. I also semi-defoliated the the interior of the lower branches leaving the tips as I need a lot of thickening of the lower branches.
My routine this year has been early morning watering and weekly fertilizer applications of peters 20-20-20 at about 1/3 recomended dosage and some organic fertilizer once every six weeks. I have not repotted this tree for two years but the drainage seems to be fine. As far as sunlight goes it's been very rainy here in New York so when it's not cloudy my trees get sun from early morning till mid afternoon.
I know slip potting this time of year is probably not my best option but if it's the roots I'd really like to know. What to do? Keep it in the shade for a week or so and hope it stops, spray it with something, or both.
