Treat the affected tree every four to six months for best results. This helps to pull the pH down which in turn allows more iron to be available for the plant. Iron sulfate is of course sulfur which, when combined with water, turns into a weak sulfuric acid solution. Of course, the thing you are trying to do is to bring the pH down in your soil, and this can be done easily by adding iron sulfate. The good news is that this iron deficiency is easily treated using several products or a combination of them. Left unchecked, it can eventually kill your tree. This will stunt the plant even if it’s well fertilized, so if you’ve been following a fertilizer schedule, but you are seeing some of these signs, then this is probably what’s going on with your tree. As it progresses, necrosis sets in, and the leaves will actually turn black if untreated. It starts as interveinal chlorosis, which is when the area on the leaves between the veins begin to turn yellow or red. The higher the pH, the worse the condition gets. If the pH is above about 7.5-7.7, the iron gets tied up chemically and is not available to the plant, even though there still could be iron present in the soil. It’s caused by high pH in your soil, which in turn causes an iron deficiency. Since I know it’s way too early for that to happen naturally, that appearance is usually caused by a condition called iron chlorosis, and it’s easily treated.Īutumn Blaze and Hot Wings Maples seem to be affected most often, and although it usually affects maples, it can also affect other trees. One of the maple trees in my yard is looking like fall has arrived because it is already turning red.
