palm tree maintenance
We planted thirty palm trees in Iowa. This is what we have currently done to protect the trees this winter. Put heat tape in the ground around the root ball to prevent the ground from freezing. Wrapped each tree with heat tape, covered with insulation, then wrapped with burlap, then wrapped with christmas trees. The heat tape is supposed to be self regulating (as the temperature rises, the wattage generated drops). We are taking temps when the heat tape is on, and are discovering that we may have over done it as temps have reached as high as 120 degrees. We currently have not done anything with the fronds. Have been told that they have to be protected from freezing, but also have to breath. Any Suggestions are welcome.
