I have 3 green and 3 red gooseberry bushes. They are 5 years old.
Here is one of the bushes. You can see the berries in development.
The green gooseberries get small caterpillars that eat the young leaves. The red gooseberries don't have this issue.
I get about 6 pints of berries. I eat them fresh or make jam out of them.
The bushes have sharp thorns but they are easy to avoid.
