Q.Should I Keep Watering My Newly Planted Perennials After Frost?
I planted new perennial garden early October. The first 8 or 9 days I watered every day, and then went to every other day. Last week we had our first frosts and I stopped watering. However, after the frosts, we have been receiving more warm weather. Should I continue watering, since we have not had any rain during that period?
