This is in regard to a response to a post by Dennis Kramb, echoing some
concern by Art Bern about leaf spot and foliar application of fertilizer.
(If you don't have leaf spot problems, then ignore this message.) I'd think
that foliar application of Miracle Grow would be detrimental to the leaf
cuticle, which is waxy, and is the first line of defense of the iris against
fungal penetration. Commercial herbicide applicators like to combine
post-emerge products with liquid fertilizer for just this reason (removing
broadleaves from wheat), as it breaks down the leaf's resistance to
absorbtion of the herbicide.
The analysis of the MG products usually is a good N-K balance, which is
desirable, both of which should make for production of a good bloom stalk.
Has anyone experimented with using more potassium (K) in their analyses, as
a "million years ago" when I studied this, it was thought to offset/prevent
"brittleness," caused by too much N?
