Look for varieties that are resistant to the most common tomato diseases in your area. Check the seed packet or plant tag for information on disease resistance.
2. Fruit Size and Flavor
Choose a tomato variety that produces fruit that fits your preferences for size and flavor.
3. Plant Size and Growth Habit
Consider the size of your garden and choose a tomato variety that fits your space. Also, consider the growth habit of the plant, such as determinate or indeterminate.
