I dust things with sulfur. Tulips,daffodils,glads and irises. Not to mention
black spot covered roses. It's fungicide [I think] not to mention plants need
a little. If the plant is out of the ground it isn't too hard to put some
into a bag and shake the bulbs etc to coat them with sulfur. I doubt the
little that gets stuck to the plant really moves soil Ph too much.

Gypsum shouldn't be that hard to find but I'm not sure it will help. The
sulfur might be bound and not usefull. Lime [calicum carbonate] raises Ph
but I think it's the carbonate more then the calicum.
