iron chelate spray defoliating blueberry bushes?
I have some blueberry bushes suffering from iron chrolosis,distinct yellow leaves with green veins, with some bushes with all yellow leaves. I have placed sulfur around the bushes even though that will take a few monthes to go into effect. I thought in the mean time I will boost the the plants by doing some foliar spraying with iron chelate. I have given around 7 or so doses. I have noticed after this last spray that some of the bushes are defoliating. In fact I think I might lose one or two bushes. In some of the other plants I have noticed some greening up of the leaves and with that has come a boost in growth. However, in a few bushes it looks like they might bite the dust. Has anyone experienced this?
