I knew there was something I'd forgotten to do this winter! Have I left it too late to spray my nectarine tree for peach leaf curl?

Welcome to the site if this is your first post 

This RHS advice says you should spray twice, two weeks apart, in late January and early February.

or grow Avalon Pride which is partially resistant or cover with plastic netting instead

Thanks for both replies, although neither have answered my question. I know the recommended dates for spraying, but as I forgot I wondered if it was feasible to do it now?

The RHS link gave the dates for spraying.  You are now nearly 2 months beyond that date.  I would therefore conclude that you are too late.

Thanks, I'll just have to hope for a dry spring instead!
