this is the first year i've had any time to dedicate to the garden. have planted some beautiful old-fashioned roses, perfect roses, which now have leaf mould, or at least i think it is. what, if anything, can i do?
Assuming you're not trying to garden organically, get hold of something like Rose Clear from a supermarket or garden centre, plus one of those pump-action spray bottles. Roses are a bugger for greenfly, blackspot, mildew etc. If it wasn't for the flowers they often wouldn't be worth the bother If the disease looks particularly bad, prune off the affected stems and dispose of them (not in your compost bin) before spraying.
thanks cogito, i was vaguely thinking of an organic solution, or rather one that i didn't have to go to the shops for, but for the sake of my new lovely roses i will get some rose clear. will they recover?
They're pretty tough things, roses. Even if they look totally knackered, prune them moderately in the autumn, harder in the spring, and they should have clean new growth for next summer. Start spraying as soon as they get any decent growth and you can deal with pests before they get a foothold. I'm sure there are some organic solutions but every time I listen to people on GQT talking about squishing greenfly between fingers I rather go off the idea
