Re: That Tangerine again! Clementine,
Sorry to bust your chops here but I recalled reading something several years ago, and thought I should look it up. Here is what it says "just as in medicine, prescription befor diagnosis is malpractice; the arborist must understand tree biology before embarking on a program of care". Text from pg 1 of Arborists' Certification Study Guide, International Society of Arboriculture.
While your photos are fantastic, it is near to impossible to diagnose ailments that you speak of on the internet. The members here can offer you a best guess diagnosis, but it is just that, a free best guess.
The new growth that you speak of appears to be a bit chloritic, usually due to the lack of iron. But due to light issues of the photos, and other things that this specimen may of had done, I will reserve any opinion.
I was going to recommend a home-owner safe spray that you might want to try, but I wouldn't want to be the reason for your trees death.
At this time I believe that you have learned a great deal about the field of arboriculture. You are wise to the questions to ask and able to rely on the people here for a second opinion. Think it might be time to ask for a referral to an arborist in your area, to do some hands on inspection.
I wish you good luck in your tree endevours. |
