first welcome to GOY. there are loads of things you can grow in grow bags, letuce spring onions toms cucumber, carrots radish.to be honest how long is a piece of string. try what you want go for it. good luck. :~))

Depends what they are? I put in 2-3 tomato plants or 2 peppers. The other things I grow in the veg patch but most things will grow if you water them well and do not over plant them. It also tells you on the bag how many.

Squash and melons are hard to do in a grow bag, just because their roots systems are so huge. Practically any other annual vegetable or flower is fair game.
