At least, I think it's a problem. I had an orange tree planted this past spring. It already had small green fruit on the limbs, but now they have turned brownish and have little growths on them. The leaves appear healthy and the fruit seems to be growing but the color is certainly not orange. Help! Does anyone know anything about this condition?
PS - the landscape people who planted the tree have gone belly up so can't ask them.
