How to grow it
You'll usually get these as bare-root bushes, so you're looking to sow them anytime from November right through to March. When they arrive, get 'em in the ground sharpish. Dig a good sized hole, plenty of room for the roots to spread out nice and wide, then backfill with some decent compost. Give it a good watering in once it's settled and make sure it's got enough space around it, they like to spread out a bit, you know.
Jostaberries are cracking for giving a good yield, but they do need their space to get established properly. Once the risk of the last frost has well and truly passed – usually mid to late May up here in the North, a bit earlier down south – you can get them planted out. Give each bush at least 1.5 to 2 metres, they're big lads and need room to grow without being crowded out.
