Sulphur drops the soil pH and concurbits prefer pH 6 or more. I don't know
of any other vulnerability, maybe others can comment.

on my package of sulfur powder it says not to use on curcubine plants.
what effect does it have on the plants if used? and would it be safe to
put on ground now and still plant out pumpkins next year?
thanks
