The Nagami kumquat is a good container plant. I hope so! I bought one last month. They grow actively in high heat, but need nighttime chill for good color and flavor.

Here is a link that might be useful: What's Growing On?

many fruit trees will do well containers on the west facing side, but will also need protection from the hot summer sun with shade cloth for many years until a fuller canopy develops. the pot itself should always be shaded in our summer climate to avoid overheating roots. you'll need a larger sized container if you expect to hold a decent Amt of fruit. I've nectarines , citrus, cherry and blueberries both standard & dwarf stock in containers.

You could add more citrus, like any of the 4winds 'dwarf' trees (most retail ones are on trifoliate). Or true dwarf peach, nectarines, or apricot on from Dave Wilson nursery (nectazee, honey babe, pixiecot, etc). you could buy new 'standard' full size trees & they tend to dwarf naturally dropped in the container, but the trees listed above are a little easier when you're starting out.

Thanks for the replies.

I'm going to a plant sale this weekend. Ill have to look out for a dwarf cherry tree, that sounds awesome. Or maybe an apricot.

The seller's ad says they have gooseberry bushes. I would love to grow some. Do any of you have experience growing them?
