Hi Ladies,
Is there someone that knows how to treat black spots on my rose bushes? They were so beautiful, and now they are going downhill fast.
Please help me if you can.

I've been battling the same thing on a couple of mine. I've been taking off the affected leaves, cleaning up around the bush so the fungus doesn't splash up while it's raining or I'm watering to infect more leaves, I've been alternating between spraying with baking soda water and a milk spray. We've been getting so much rain down here (I'm happy for it, for sure) that I haven't been able to really put the sprays on but the roses are looking better. As with anything though, spray any new product or home made solution with caution and care. Try not to do it on super hot sunny days as the sun can burn the leaves or stress the plant. I've been looking online for other cures as well and saw this site
http://www.sustainable-gardening.com/roses/comingup.html
I've not heard of the mouthwash spray and am curious to see if it works or not.
This site http://www.soilmender.com/resources/recipes.php
explains how to make the baking soda spray. I'm also interested in the compost tea. I have a batch brewing in a bucket outside. I stir it with a stick a few times a day, I can't afford all the fancy bubblers and aerators some sites say to do. I'll strain it with an old pillowcase. Next time though, I plan on putting the compost and manure inside the pillowcase and sort of tea bag it, less messy I think. So, my next plan of action is to continue cleaning up the infected leaves from the plant and give it a mist of the compost tea. If all else fails I will try the mouthwash on one bush but I like the idea of the tea a bit better as it fertilizes too. Hope this helps. |

Abigail, We have had a ton of rain everyday since Saturday. I will try some of the things you mentioned when there is a day without rain! I thought someone somewhere on here had a recipe that you use the Fels Naptha soap? Have you heard of that?

| Also- I've just read the book "Nelson's Guide to Florida Roses" In it, the author recommended using the time release fertilizers to cut back on the risk of over fertilizing. I use well rotted cow manure, compost (eggshells, tea bags, coffee grounds ect)and was using water soluble fertilizer that was given to me. He stated in the book that sometimes when roses are over fertilized they can become shocky and more succeptable to the black spot. Just another thing to consider. Mine are in pots, according to size and I'm thinking of planting them in a raised bed made out of used tires to give them some more leg room. I just can't put them all into the ground because I'm still hanging on to the dream of our own land one day. The containers also help me when one of my plants may need to be moved to a "time out" or something...lol. |

Thanks for the link. As soon as I saw the link, I remembered that is where I had read that! I will try their method. I love roses, and the only problem I ever have, is the "blackspot".
You keep those roses where you can dig them right up! I feel that you will be able to move them to a more permanent home soon!!
