Q. I s there a spray for mesquites like there is for olive trees so I wouldn’t get the pods? A. There is no chemical that is specifically labeled for Mesquite trees and keeping the pods off. There are a couple of chemicals that might work. Here is a good link from the Morton Arboretum on reducing fruit, and this would include pods, produced by ornamental trees. http://www.mortonarb.org/trees-plants/tree-and-plant-advice/horticulture-care/preventing-or-reducing-fruit-ornamental-trees The problem is we don’t know the right concentration or the correct timing. I will post this on my blog and also on the Yahoo discussion group desert horticulture and see if we can get some discussion on this. I have Sweet acacia on my property and it drops pods all the time but I have a rock mulch that is multicolored and my landscape is not formal so it blends into the mulch. But these pods are much smaller than Mesquite.
