Roses With Root Stock
(Yorba Linda, CA, USA)
QUESTION: My rose bushes are abt. 25 yrs. old.
Many have excessive growth of root stock.
No matter how much I prune down the root stock, they keep coming back.
Should I remove those bushes & plant new ones?
ANSWER: Yes, you should remove them, as they will never be good rose bushes any more.
The graft failed after so many years.
If you plan to plant other roses in the same spot, you need to totally remove all the soil where the old roses grew, and replace it with new soil.
A new rose will not do well growing in the same soil, that another rose has grown in for so many years.
