I notice old Jacks autumn rasps are fruiting, but my lottie neighbours gold rasps aren't even in flower.
Rohaise - Rasberries are shallow rooting, wo be careful when hoeing around them, and are woodland plants prefering light dappled shade. Too much feed will encourage lashings of floppy stems and leafy growth. Planting too deeply could also do them in. Mine are left to scramble at the edge of my apple trees and this year, thanks to the rain, I am picking huge raspberries 2inches long, fat, juicy and packed with flavour. The only feed mine have received was a sprinkling of pelleted chicken manure at the start of the year. Once fruiting has finished, all the fruiting canes will be chopped right down to ground level, along with any damaged new stems. The rest are left to scramble away ready for next year. Mine are Glen Ample, and I would heartily recommend them.
