Yes it's good to spread the crop over a couple of months so you don't explode with strawbs. Plus it means you can always find a time to do jam, whereas with my luck I'd be on holiday when they cropped and the birds and my lottie neighbours would share them and I'd have to buy more for jam.
I planted Gariguette, Symphony and Marshmello. they're all fab though the first 2 succumbed to the excess of water last year. I've done raised beds now and will plant more in them.
