trouble

I intended to post pictures today but my camera fizzled. I have a beautiful square foot garden.  In all Ive 4 4x4 foot raised beds and 1 4x8 foot bed. I'll post pictures later.  The reason I mention this is that my squash has "blossom end rot".  That is when the developing squash get black soggy rotten areas on the end where the blossom started.  After doing some research and testing the soil, I found that I needed more calcium in the soil.  I couldn't eat enough eggs to provide the shells for calcium for the garden so I called the ever present mother(don't know what I'm gonna do when she is gone), to discuss the problem.  After hashing out sources of calcium, she told me that an elderly man had advised my brother to put "Tumms" around his plants to provide them calcium.  Ding-ding! being a nurse I immediately knew that "Tumms" is pure calcium carbonate.  Duh, why didn't I think of that!  I prefer doing solely organic but, needed a quick fix. I removed the blossom from the end of the newly developing squash and faintly scratched the end in order to make a "scar" then just before the Frog Strangler rain, I placed 3-4 "Tumms" around each plant.  I just hope it works.  I love squash and I can't bear the thought of not having fresh from the garden veggies.  Updates and pictures to come.  (Fingers crossed).
