Interesting but my runners are not very healthy. I *think* it's
manganese deficiency. The older leaves get mottled between the veins. At
some stages it's quite pretty. at first, I thought it was Magnesium
deficiency and used the MgSO4 spray I fixed the tomatoes with but no
joy.
Apparently, it's a problem with alkaline soil and beans. They can't get
Mn out of such a soil and a foliar spray of Mn is the only way. Anyone
know of a source of Mn for a spray? Or should I acidify the plot?
I would have thought that an impossibility. There is no acidic counterpart
to lime as far as I know.
