Tomato Selection 101 – Growth Habits and Harvest Windows
Choosing the right tomato is the first step toward a successful season and it all starts with understanding how the plant actually grows. When you look at our tags you will see the terms "Determinate" and "Indeterminate" which describe the physical habit of the plant and how it produces fruit.
Determinate Varieties
Often called bush tomatoes because they grow to a compact size and then stop. They are the best choice for gardeners with limited space or those who want to grow in patio containers.
These plants produce their entire crop within a very short window of about two to three weeks. This makes them ideal for home canners who want to process a large batch of sauce or salsa all at once. Because they stay small, they only require a lightweight cage for support and very little pruning throughout the season.
Indeterminate Varieties
These are vining types that continue to grow and produce fruit until the first frost of autumn. They can easily reach six to eight feet tall and require heavy-duty staking or tall wire cages to keep them upright.
These plants are the favorites of fresh-eating gardeners because they provide a steady supply of tomatoes for daily salads and sandwiches. You will need to keep an eye on "suckers" which are the small shoots that grow in the crotch of the branches to help maintain airflow and fruit quality.
Maturity Dates
Mixing your maturity dates to get the most out of your PNW garden we highly recommend mixing your maturity dates. Every variety has a "days to maturity" number that tells you how long it takes to go from planting to your first harvest.
Early Season Types: Varieties like Early Girl or Stupice are bred for cooler climates and will give you fruit in about 55 to 65 days.
Mid to Late Season Types: These include the big beefsteaks and classic heirlooms that often take 80 days or more to ripen.
By planting a mix of both types, you ensure a longer harvest window and prevent the frustration of having all your tomatoes ripen in the same week. This strategy protects your garden against unpredictable weather and keeps your table stocked with fresh garden flavor for months on end.
