Q.Loquat
I have a potted loquat tree about three years old that I planned to plant soon. It has started tutrning brown around the edges of its leaves. What should I do. Also, when is the best time to unpot it and plant? Iam in lowcountry South Carolina, near Beaufort.

Make sure the plant is not sitting in soggy soil. Root rot could turn the leaves brown and drop.
