Roses
We have several rosebushes in our garden and we have discovered that they, in some cases have severe 'blackspot' disease. I have tried spraying them with fungus removal and have also tried 'jeyes fluid'. If they persist will I have to cut them right back in order to begin proper treatment?.

I'd never use jeyes fluid on a plant I wanted to survive.
Remove the affected foliage by all means, but don't prune them , mulch with good well rotted manure, or garden compost, or give them a good feed.
Sounds like statin' the bleedin' obvious, but healthy plant are less likely to get ill.
Thanks for the advice. When I said I've used jeyes Fluid it has been watered down ie 1 tablespoon to1 litre of water. This was advice I got from the internet and from my father-in-law some years ago.
Richard, black spot has never killed a rose. Feed them , water them, and keep them strong and they're more likely to shrug things off.
In Devon we are blessed with good , clean , unpolluted air and blackspot is a problem.
I've just come back from RHS Rosemoor and they have it there , but not in a major way.
Thanks very much. I take on board everything you have said.
1Runnybeak1. Thanks very much for the advice.
Hi Richard,
Don't leave any of the rose leaves on the soil over winter. Pick them all up and bin them (not in the compost bin) and that will help to break the cycle. Some years are worse than others but getting rid of infected leaves can make a difference.
Ceres. Thank you for the advice. I have had some excellent help on this forum. I will try and follow it all.
Richard, feel free to post another "issue" we're only too happy to help.
Hostafan1. Cheers will do.

We love a challenge
