Hybrid roses in spring
Hello there all.
I have two hybrid rose bushes in medium sized pots on my patio. Last year one of them suffered from aphids and the leaves went brownish yellow too. I trimmed back dying leaves to aerate the plant as i not keen on spraying roses - as they were in bloom at that particular time.
Question - whats the best start i can give them this spring as to feed/mulch? Also when and if would you recommend using a pest control should the white sticky rice like critters return?
