that I’ve consistently done best with, and in the past few years I’ve grown enough to last me year round.
Thankfully even last year was no exception and I still have about forty in store waiting to be used. I grow mine from sets as I find this much easier than growing from seed.
I buy them at the horticultural trading shed, which in previous years have always been the varieties Sturon and Turbo. This year we’ve switched suppliers and the latter isn’t available so we’re offering Centurion instead. Both that, and Sturon, are excellent varieties and have the coveted RHS Award of Gardening Merit. They’re on sale at £2 per kg, with 60 of each only costing me 50 pence.

Have a good week!
