Hi Jont1 or anyone,
What fungicides are you using on your roses with crosses for Blackspot and other diseases? Are you using any fertilizers? Thank for any and all advice.
I use a combination of mancozeb and funginex every 2 weeks for fungus control of BS and PM. I have some downy mildew this year and am using Alliete powder by itself mixed with water to spray for that.
If/when I have spider mites I spray the pheromone Stirrup-M combined with Avid or Kelthane to rid me of these pests.
To fertilize,I spread Mill's Magic Mix every 2 months and a granular like Shake-N-Feed or Osmocote. I ususally add epsom salts to the MMM as well. I spray Miracle-Gro combined with Fish Emulsion and an Iron Supplement every 2 weeks. I find the iron is especially important for potted plants. Finally, I spray Messenger once per month to promote vigorous growth and support disease resistance.
Hi Jon, thanks for your reply. Do you use all of these even when you have hips growing on your plants?
