Already sprouting? Yikes - most canes haven't gone properly dormant yet!
Mine do ok, Sarah, I've got them under the Bramley and they romp away. I have a thicket rather than a row these days, and a freezerful of fruit as a result.
I put potash on them in April, occasionally manure if I've got some and they just go mad. Took a couple of seasons to get going but they're now a jungle and I have problems working out which is summer and which autumn as they sort-of grew into each other when I wasn't looking.
