With the very warm weather in November, many of my perennial plants began to send up new growth even after all the leaves had previously fallen. Some of these plants were roses, hydrangeas and iris. Will this have a negative impact on next year’s growth and flowering? Thanks, Diane
They should be fine. If they produce flowerbuds that then freeze, you may lose flowers that would appear in spring but the plant will survive. To help them stay cooler you might consider raking leaves onto the beds to keep the sun from warming the soil. We had this problem (even worse) during the winter od 2011-12. HERE’S a link to a blog post I wrote then that addresses the issue.
