I planted a hollyhock. It is 8 feet high and has got some pink flowers coming out on it. When do I cut it down and how much?
Hollyhocks are generally recognized in the industry as herbaceous perennials, meaning they die to the ground during dormancy. They are a short lived perennial. Most varieties will last 3-5 years. Some people refer to hollyhocks as biennial plants.
When hard frost takes it to the ground is the time to cut it back.
