    I have got a really nice yellow climbing rose it recently becme riddled with black spot. It's up for the chop but what I want to know is can I collect the seeds from it or will they have inherited the plague as well ?? I've never tried roses from seed before and would like to give it a go.

    Is it really beyond redemption, Rob? I have roses that were pretty bad but with some care and attention they're coming back year by year. It's more a question of hygienic husbandry (i.e. clearing up the infected dropped leaves and cutting back the infected stems and spraying regularly).

    I believe as far as seeds go, it rather depends upon the type of rose. Most roses are hybrids, that is a cutting grown onto a wild base. So seeds might not take and if they did might not be true. That's not to say you couldn't give it a try. Anything's possible!

    Mercy Rob, please, Black spot won't kill your rose - tis just unsightly when it gets hold and it can be kept under control.

    Michaelmas daisy has it right - remove as many of the diseased and fallen leaves you can and burn or destroy them. The fungus that causes black spot overwinters on the fallen leaves. Then as soon as new leaves start forming next spring, spray with something like rose clear. Usually needs once every two weeks for four applications (late evening to avoid the bees and other useful predatores).

    Works believe me - I got quite a lot of roses now, and Nick an expert on roses got me getting to grips with it and its worked a charm.

    I seem to have problems with blackspot every year.I do the same as MD and clear up on almost a daily basis.( Having retired / no granchildren /oogles of time).Then as Fran suggests spray with rose clear. My climbing Iceberg was hit bad this year but is doing okay now.

    Thanks for taking the time to reply.

    I was under the impression that black spot was a bad thing in a garden but I shall save it from the chop and continue training it along the fence. I'm going to keep it sprayed, and I'm going to give the seeds a go now.

    Thanks for bringing me up to speed

    Rob
