Hello! Cut out any shoots which have fruited. Tie in new shoots for next years crop. This can be done now.

when you get your plant under control grow all your stems
to one side of your plant the folowing year grow it to the oppisit side on wires the fruit will grow well
once it has fruited cut the stems back to about 4 ins from the soil good helping of maure will benifit the plant the more food your plant gets the more food you will get
if you want more plants put a brick over a tip on the soil next spring one new plant
good luck
