The best soil temperature for seed germination is 60 to 70☏. You can grow plants from seed in a greenhouse, hot bed, cold frame, or window box. It’s often the only way to get plants of rare heirloom cultivars. Finding out what is best for your garden is definitely part of the fun of growing tomatoes.Īn easy and inexpensive alternative to buying transplants is to propagate tomatoes from seed. Depending on your preference and growing environment, there are many others to choose from. These cover only a small fraction of the many cultivars available. The cultivar suggestions on page 3 are based on field trials in Corvallis, Oregon. Anthocyanins are pigments that give fruit their red, purple, or blue color. Some are newer cultivars, such as ‘Indigo Rose’, which is distinguished by a very high anthocyanin content. Note that not all types in this category are true heirlooms. These may include heirloom types that vary tremendously in size, shape, color, taste, and other attributes. When temperatures warm up, the tomato flowers will be pollinated, and the fruit will have seeds.Ī number of tomato cultivars do not fit the descriptions above. Because they also have the earliness of a determinate growth habit, these cultivars will set fruit during the cool Oregon spring and early summer. A number of cultivars bred by Oregon State University have this trait (designated with a * in tables 2 and 3). They will be productive even when growing temperatures are too hot or too cold for normal tomato fruit set. Some tomato types can set fruit without fertilization by the pollen (parthenocarpic fruit). The seed packet will generally indicate whether the cultivar is an F1 hybrid. These are uniform and can be more productive than traditional types, but they will not breed true from saved seed. Self-pollination helps maintain many traditional types as pure lines, which means that one seed has the same genotype (genetic composition) as all others, and will breed true from generation to generation.Ī number of modern cultivars are F1 hybrids. Tomatoes are normally self-pollinated, although some wild relatives and certain cherry types have a tendency to outcross (require another cultivar as a pollinator).

As a result, lateral shoots are not usually removed. They produce vigorous lateral shoots that often terminate in a flowering truss (cluster). Semi-determinate tomatoes, especially beefsteak types, have a growth habit between that of indeterminate and determinate types. These types of tomatoes are especially well-suited to staking and pruning in the garden. They are often referred to as “vining” tomatoes, although they cannot wrap themselves around a trellis the gardener must tie their stems by hand. As a result, fruit is produced continually and ripens over an extended period. These types of tomatoes do not produce terminal clusters of flowers, so the stems continue to grow until they are killed by frost. Indeterminate tomatoes grow and produce flowers all season. So, these types of tomatoes grow well in containers and, because of their concentrated ripening, are well-suited for processing. Also, their compact growth habit makes them easier to protect from frost using techniques such as frost cloths and “walls of water” (see “Water rings and tepees,” page 7).īecause of their branching and flowering characteristics, determinate cultivars tend to be fairly short (3 to 4 feet tall) and bushy. This type of tomato is a good choice for a cold-climate area because it matures early. As a result, determinate plants tend to ripen their fruit over a short period, usually just a couple of weeks. The main shoots and branches grow vigorously and then produce flower clusters at their tips, which stop further stem growth and allow the plant to begin ripening the fruit. Determinateĭeterminate tomatoes have several main stems that produce side shoots freely. Growth habit determines the size of the plant, the pattern of fruit ripening, and the type of plant support and pruning the plant requires. Tomatoes fall into three categories of growth habit: determinate, indeterminate, or semi-determinate. Local, regional and community food systems.Commercial fishing, crabbing and clamming.
