What is the best variety of tomato for a container garden?
There is no one tomato that is best. Your choice will depend upon your situation.
There are compact 'determinate' varieties that will grow in most containers. If you have a large container (5 gallon or more), you could even grow an 'indeterminate' tomato. You'd need a trellis, too, probably.
Here is our webpage on container gardening to get you started: https://extension.umd.edu/hgic/plants/container-gardening Be sure to look at the links, too, for how to plant and how to maintain it (watering, fertilizing, etc.)
Most seed catalogs will give good descriptions of what to expect from each variety, whether it would be good for a container, compact growth, etc. Look for good disease resistance!
