After the roses are pruned, what happens next is fertilizing! I like to use a slow release fertilizer and I always add a few inches of compost around the rose. Try to keep it off of the stems. It can possibly cause damage to the stem.
I do NOT use a systemic application to my roses -like Bayer Advanced 2-1 Rose care. The active ingredient is imidacloprid and this chemical is being closely studied for its effects on bees.
Anything that might kill bees, or butterflies and other beneficial insects are not going to be applied on my property. I am a beekeeper and its hard enough keeping them alive, without adding any other potential hazards.
The University of Minnesota, Extension service reports, "Systemic neonicotinyl insecticides used on landscape plants and crops are considered as a major factor in pollinator decline." Dr. Vera Krischik is currently studying the use of this insecticide and its relation to colony collapse disorder.
This insecticide has been banned in France and Germany and in my little corner of Idaho! I hope yours as well.
What do you use to fertilize your roses? If you have any questions, let me know. I am happy to help you!
