Mango Tree Leaves Looking Sick?
Hello, all. You've assisted me in the past with my questions about my mango tree. I need your expertise once more.
I have attached two photos of my Cogshall, which was planted from a 3 gallon pot three years ago. The tree has yet to produce any flowers or fruit, but I am hoping and expecting to get my first taste next summer around this time of year.
Anyway, the tree had a big growth flush about two months ago and overall it seems to be doing fine. But I couldn't help notice that all the new leaves from that flush appear as the ones in the photos below. Any idea what is going on? Some mineral deficiency would be my guess, but I'm not the expert. I have given the tree one light feeding of fertilizer about a month ago with Vigoro Citrus & Avocado Plant Food, 12-5-8 plus minors. Last week I also fed it with Vigoro Water Soluble All Purpose Plant Food, 24-8-16, but at half the recommended dosage.
Any opinions? Thank you.
