Bob,
I use K-Mag in my orchard but only when my soils lab recommends it and
only in amounts as recommended by them. I would strongly recommend that you
do likewise.
Anyone using K-Mag (Potassium Magnesium Sulfate) to size up their fruit? I
have heard different recommended application times. Some say it should be
applied in like February and others later in the season. Is there anyone
out there that can enlighten me and others on this item?
