floating row cover
The official low temperature this morning was 41 degrees F in Des Moines, but the frost on the narrowleaf zinnias, at left, prooves that it was colder in my yard. My home is in a frost pocket, despite its location at the top of a hill. Every time the weather forecast calls for “scattered frost”, it’s a sure bet that ice crystals will develop on exposed plants.
Last night I prepared for the cold by moving container gardens under the deck canopy, onto the front porch, or into the garage. I also pulled out the floating row covers to protect tomatoes, peppers, and some of the more cold-sensitive bedding plants, such as coleus. But Christo-draping the yard with fabric can only go so far. Inevitably, some annuals remain unprotected.
I may have salvaged some of the uncovered flowers by watering them early this morning before sunrise. After melting the ice out of the hose, I sprayed water on the icy plants to melt the frost. If the ice crystals were only on the surface of the blooms, this may be enough to rescue the frosty flowers. I hope so. I’d like to get another month of color from them. Mid-September is simply too early to call it quits on the gardening season, don’t you agree?
