Q.Will I have trouble growing concord grape in zone 10?
I just joined a garden club and got a grape vine. Does it need shade for zone 10 in CA? No special instructions were given. It also came in potted plant form– is that a problem?
Grapes will be suited to grow in container, actually. It will need a fairly large container. At least 15 gallons. The problem with planting in your zone isn't necessarily the heat, but that it won't get enough chill hours in the winter. Especially Concords, since they are marketed as a cold hardy variety. There will be nothing that you can do to combat this. It may still grow and produce a little, but I would not expect a good harvest from these in your area.
