Pecan seedlings with drying leaves : please help me!
I'm from Italy and asked you some questions about pecan cultivation in the last year.
Now, I have a new question for you!
I have some pecan seedlings born about a month ago.
During the first day I noticed some black spots on them and I thought it could be scab (maybe infected nuts) so I treated them once with Tebuconazole and a second time with mancozeb (it is used yet in Italy).
I have a third light treatment and after 2 days some plants started to show black vein spots and day by day leaves started to turn brown and dry.
Last year I had the same problem and my seedlings died one by one but, as I remember,7 I didn't gave any treatment.
Someone told me it could be excess of water.
Last week I put them in a tall homemade pot and I noticed that the bad ones had a spiralized taproot.
According to you what's the problem and what can I do?
I put them for the first month in the shadow and now have them where they receive about 3-4 hours of early morning sun.
I don't know how to expose young pecan seedlings, can you help me about it?
Cheers from Italy!
