Gooseberry in the UK

Right, so you're not really 'sowing' gooseberries from seed, not usually anyway. Most folks, like me, start with bare-root bushes, which you plant straight out. You can get these in the dormant season, from November right through to March, before they start putting on new growth. Dig a decent hole, big enough for the roots, and give 'em a good drink of water once they're in. Make sure the soil level is the same as it was in the nursery, or just a tiny bit deeper. They'll settle in over winter and be ready to get going when spring arrives.

Once your bare-root gooseberry bush is in the ground, it's mostly about letting it get established. No faffing about with pricking out or hardening off like you would with seedlings. Just make sure you've given it enough room on the plot, about 1.5 metres between bushes is good for air circulation, like it says in the GrowMore CookMore app. That helps keep them healthy. They don't usually need much support, just grow into a nice sturdy bush.
