Thanks for the tips on potting up for next year, is there a particular type of compost you'd recommend? I've been using Leavington multi-purpose John Innes from a local garden centre, there's a Wilkinsons very close as well. I've also been using Wilinsons own wonder grow all-purpose soluble plant food, I've just checked the label and it's 16,10,27 with Mg and trace elements (B,Cu,Fe,Mn,Mo,Zn)
