How to grow Jostaberry
in the UK
Sow November to March, plant out December, harvest July to August. About 130 days from seed to plate.
Now then, the Jostaberry. It's a proper cracking fruit, a real hybrid of blackcurrant and gooseberry, you know. They're vigorous on the plot and the best bit? No thorns, which is a proper bonus when you're picking your harvest, to be honest.
Sowing
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.
Growing on
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.
Looking after it
Keep an eye on the watering, especially when they're young or if we have a dry spell. A good mulch of compost around the base in spring helps keep the moisture in and feeds 'em a bit. Just like blackcurrants, you'll want to prune them by removing the oldest wood each year, encouraging new growth for a better crop.
What goes wrong
Now, even the toughest plants have their little issues, don't they? Sawfly can be a bother on the leaves, so keep an eye out for those grubs. Mildew sometimes crops up too, especially if it's a bit humid. Just make sure there's good air circulation and deal with any problems sharpish, it helps to keep them healthy.
Harvest
You'll be harvesting your jostaberries from July through to August, depending on the weather and the variety. Pick them when they're proper ripe and dark, they'll come off the bush easily then. They'll keep in the fridge for a few days, but to be honest, they're cracking for making jam, pies, or just freezing for a taste of summer later on.

I always say, having no thorns on these is a proper blessing when you're picking, makes the job so much easier, you know what I mean.
