If you decide to grow toms be mindful, some varieties are better grown under cover for instance in a GH and don't grow well outside in our cool climate. You need to read the instructions when buying.
There are also determinate and indeterminate varieties of toms.
I maybe wrong but determinate toms are bush tom's for instance Tumbler, Tumbling tom, Red Alert and Garden Pearl. These grow well in hanging baskets and tall pots, they don't need stakes because they don't grow very tall. A cane, close to the stem to which the stems can be tied is advisable though as they can become very heavy with fruit and a cane will add support.
Indeterminate varieties or cordon toms can grow to 5 or 6ft in height, these need staking - varieties include Alicante, Money Maker, Gardeners Delight, Golden Sunrise and Sungold, not all sutable for growing outdoors.
Hope this is helpful. Some of the bush one's are really easy to grow in pots and hanging baskets providing you choose the right variety.
