Daniel and I have a contingency plan for hail storms, including hard hats and tarps to cover our garden in the case there is a storm. We have, in the past, been able to save our garden by covering our garden before the storm hits. One year we could hear the hail coming, it sounded like a train and had fair warning! But this year we didn't see the warning in time.
After it was over I went out to salvage what I could by removing the ice from the seedlings. The tomatoes and peppers took the biggest beating. We had purchased these as seedlings so the good news was that they could be replaced with a visit to the local nursery. Everything else was green but had few leaves, so the verdict was out.
Update: We replaced the tomato and pepper plants and everything else recovered. The hail storm put our growing season behind a few weeks. However, it is October now and we are still harvesting tomatoes, collards, Swiss chard, kale and cabbage.
