Hello everyone. I have four honey locust trees that I have been growing from seed. I don’t quite know the type of honey locust tree that they are. I will post a picture of the mother with these. Up until 4 weeks ago I have not had any problems with them. But for some reason the leaves have been turning yellow and falling off. On some of the leaves they are burnt on the tips. So to recap the last few months. I planted them in the early spring when they were dormant. They were whips that I cut at 6‘8“. They produced new branches and were growing well. I placed some leaves mixed with compost manure underneath them and they did amazing. They have been awesome up until 4 weeks ago. I rigged a watering system so that I could manually water all four trees at once. I watered them manually since I have planted them. They are also getting sprayed by Sprinkler‘s. I have measured the water output from the sprinkler and it is roughly 1 inch per week on the area. I was thinking they were waterlogged from me manually watering them two times a week and the sprinkler system. So about two weeks ago I stopped watering. I have just let the sprinklers do the work. The only other change is that I placed some fertilizer on the trees about one month ago and then followed up with A little ammonium sulfate that I had left over about two weeks ago. Does this look like fertilizer burn? Or an overwatered tree? Or both?
