How do you treat boron deficiency in apple trees?
July 24, 2011 11:39PM
Apply agricultural borax to treat boron deficiency in apple trees [Malus domestica]. The rate should be 0.25 pounds for dwarf or young trees, 0.5 for mature trees, and 1 pound for very large trees. The application needs to be made in the fall or winter and should be done every third year until the problem is solved. It also needs to be done either 3-6 feet away from the trunk of young trees or near the drip line of older trees.
The easiest way is to apply a general fertiliser containing trace elements as a Boron deficiency is only part of the problem.
