Should Knockout Rose Bush Be Treated With Sugar Water

Question From: s. frith - Dayton, Ohio, United States
Q: I have a dwarf knock out rosebush. Someone told me to use sugar water on it. Will that really help and if so, what ratio would I use. Thanks very much

A: I know of no value regarding the use of sugar water. Roses should not be fertilized after the middle of August. Plain water works like a charm right now. Best And Happy Yardening, Nancy
