Sweet Tart leaf damage
« on: April 10, 2024, 05:05:05 PM »
We planted this Sweet Tart in August 2023, late in the season in the Orlando area. It spent the winter with worsening leaves and now they look like this. Besides looking like tiger dermis, what is it? Anthracnose? I didn't get to it with sulfur and copper until February when this condition was well established. Lots of new leaf growth lately; the tree seems determined to shed all of these old leaves. Any ideas on keeping this from happening again, whatever it is? On the oldest set of new leaves, there are some brown tips, so I'm already nervous. I think we got this tree from Everglades Farm because it was one of the few places that had Sweet Tarts in stock at the time. Wondered if there's any chance it's not on Turpentine rootstock and that might weaken it? We planted a Valencia Pride in April '23 and a NDM 4 in July '23 and they didn't turn out like this! The 15-gallon VP grew throughout '23 and now has eight or 10 emerging mangoes on it . . . Thanks for any thoughts!

Fertilozer burn. Trees looks good.

Mangoes grow roots first, when planted in ground. Can go many months, especially over winter, and not show any signs of growth above ground. Water when young, will also help wash out any excess fert.

Yes indeed, roblack, we certainly saw no growth above ground after the cooler months started. Would be curious how much root growth happens during that time! But thank you and gozp for pointing out fertilizer burn. I have tried to fertilize conservatively but apparently not conservatively enough!
