I'm doing the RHS advanced certificate and my tutor told me about these RHS videos so I thought I'd share it with you guys as well. They cover lots of practical topics which are generally easier to watch someone do rather than read about, very handy! (you don't need to be a RHS member to view them) Here's the link. Happy gardening
