Help!!
I need to treat some garden trellises, which have gone green in all this rain 
How do I clean off the green, if I need to, and can anyone recommend a good preservative, considering it will have roses or clematis growing up it?

Jetwash.. followed by drying for a few days then a couple of coats of cuprinol, colour of your choice.. thats what I'd do!
