On April 10th, we had a very, very light frost in the morning. THAT'S IT! I decided - off to the building supply store with a sketch and some measurements, and home with a load of supplies for a simple, quick to build greenhouse. My daughter and I began digging post holes about 5pm, shortly before my husband got home from work as it was becoming dark. "Family" said I, "We're building a greenhouse tonight, and no one is going to bed until it's done!"
So, by the light of a portable lamp, we did, indeed, build a greenhouse. The temperatures were dropping rapidly - we all had to rug up in jerseys and jackets, hats and gloves. We finished about 11pm, by which time WE were frozen. But the tomatoes were safely covered.
The funny thing is, a casual observer from a distance could have been forgiven for thinking we were working in our clandestine "weed" patch. LOL
