Horticultural Notes
2 1/2′ x 3 1/2′ Black Forest is a new Floribunda Rose with gorgeous red flowers in clusters of 5-7 on upright bushy plants. Known for its disease resistance it is a gold medal winner and won the ADR trials for the best no spray rose.
Although there is great disease resistance there are a lot of bugs that will attack roses. In Hawaii insects and fungus can be relentless so the best thing to do with all your roses is cut them back 3-4 times a year. Remove all the old damaged leaves and fertilize and you will get new growth with a bounteous show of flowers. I also like to spray with horticultural oil and Neem oil to help control fungus and insects. Aphids are easily killed with this combo oil. Note I always use these oils at 1/2 strength and spray frequently.
