quince tree/leaves looking bad
I planted a quince tree this spring, it seemed to do great initially. It even had 4 fruits on it, but it had a really rough time during the summer. It is in full sun, and I probably should have painted it. Also the cats used it as a scratching post. I wrapped he main trunk a couple of months ago and I hope I didn't do it too late.
I'll admit haven't always watered it often enough, but lately I started watering it at least weekly or twice a week, and it still doesn't seem to make a difference. It's not totally dead, but it's just sitting there not doing anything. And by watering I mean, fill the basin around it with water and let it go down.
Is this a sunburn? or nutrient/water/salt problem?
what should I do?
