I never have any luck with knockouts. After 8 years of poor performance of red ones, I threw them out swearing to give up on roses. But I couldn’t turn down a clearance price of $5/ea on these yellow knockouts last year. This is my 3rd monthly feeding of Osmecote this year and when pulling back the mulch I saw all these roots. What is going on? I have a soaker hose there and give them about an hour 2x a week In addition to the overhead (that I know isn’t good but can’t do anything about it) lawn irrigation 2x week 30 min. Please help me out before I rip these out too and plant shrubs.
