With so many tomato varieties and uses in the kitchen, it’s no wonder tomatoes are one of our most popular vegetables! We receive a lot of customer requests for additional tips and tricks on sowing and growing the best tomatoes.
When to start tomatoes:
In mild climates/hot summer areas, tomatoes are transplanted in December-April or July-Feb. Contact your county extension office or a local independent garden center for the best time for your area.
Use shallow, sterile containers with drainage (4- or 6-pack at a garden center). Transplant into larger, 3″-4″ containers once the true, scalloped leaves have emerged. Biodegradable paperboard pots (link) are the ideal size, easy to label, and easy to share with friends.

Transplanting and Supporting:
Tomatoes are grouped into two main types according to growth habit and production.
- DETERMINATE types (e.g., Ace 55, Glacier, Italian Roma) grow in a compact, bush form, requiring little or no staking. Fruit is produced on the ends of the branches; most of the crop ripens at the same time. One or more successive plantings will ensure an extended harvest period. Determinate types are often the choice of those who want a large supply of ripe fruit at once for canning.
- INDETERMINATE (e.g., Better Bush, Sun Gold, Black Krim) varieties continue to grow and produce fruit all season until first frost. Tomatoes in all stages of development may be on the plants at one time. The plants set fruit clusters along a vining stem, which grows vigorously and long. Under optimum conditions, some can grow over 15′, but in most home gardens they generally reach about 6′. Some indeterminates have a bush form with stockier vines, which set fruit clusters closer together.
- In between these two types are the SEMI-DETERMINATE (e.g., Lizzano). The plants will grow larger than determinate varieties, but not as large as indeterminate. They produce a main crop that ripens at once, but also continue to produce up until frost.
