Hi guys.. this is my first post. So please be kind We moved to a house with a lovely rose garden, however, that lovely rose garden is seriously ill! All the roses (David Austins) are covered in black spot. I began to remove the offending leaves before spraying but it is too prolific! I am completely new to gardening and caring for roses and I as such, I have two questions that I hope someone can help me with... I was wondering if I could just cut all the rose bushes right back (the steams look ill too) .Can black spot spread to other plants, as my clematis and some weeds, are now covered in spots that look very similar! Thanks guys.

Hello Andra2000 and welcome to the forums Not big on roses myself but here is a RHS page on blackspot apps.rhs.org.uk/advicesearch/profile.aspx?pid=270I don't think it is the same problem affecting your other plants it is specific to roses as far as I know but there are many similar fungal diseases that are similar and they are very prolific in wet damp weather Roses however can be cut back fairly hard as you suggest but remove all fallen leaves as the disease can spread from these The web page gives good advice

Welcome Andra. Your roses will need a boost with rose food in the early spring. There are various brands in the garden centres. I wonder if they have been planted too closely so that not much air is circulating around them.
I agree with Steve and yourself that you should cut them back. It would be a good idea to spray with Roseclear or similar in the spring.
The leaves on the clematis are just old ones I think. It won't catch blackspot.
Enjoy your new garden and please let us know how you get on.
