The form is the determinate plants tend to have flowers on long flowering stems held at the top of a relatively short plant. The fruit or vegetable produced by determinate plants is harvested once it has reached its full size.
Indeterminate plants have flowers that are produced along a growth column in elongating branches, the fruit may be harvested as it ripens and also left to ripen on the plant, for example tomatoes and some other vegetables.
Indeterminate plants are often described as varieties of a particular plant species.
A determinate tomato plant, once it has flowered and set fruit, grows for a limited time before dying. Delineate tomato plants are ideal for growing in containers or greenhouses, where they are easier to control. The growth of such plants may be supported with any vegetable trellising system. Determinate tomatoes are the most commonly grown type of tomato. The more common indeterminate varieties, however, produce larger fruit and are therefore less suited to container growing.
Tomato plants are usually grown in a manner that ensures that few (if any) flowers develop on the plant; normally by training or pruning them into growth patterns which can be simplified as decussate (do not grow opposite each other) or determinate (grow only along a central axis).
Which is better determinate or indeterminate?
When it comes to planting tomatoes, gardeners have a choice between determinate and indeterminate varieties. Which type is best for you depends on your garden size, growing conditions and preferred harvest method.
Determinate tomato plants are the most popular variety for most home gardeners because they produce an early, short-season crop that looks great in containers and takes up less space than indeterminate plants do.
Because tomato plants stop flowering at heavy fruit load, you can harvest the entire crop at one time. Determinate varieties grow as a compact one-large plant with few side branches. However, if the plant is allowed to grow unchecked after exhausting its water supply, then it will put out dozens of side branches and not flower. To support this type of growth, most gardeners use cages or stakes to tie plants into place.
Why choose determinate vs indeterminate plants?
Most determinate tomatoes produce large fruit. They also do not require a lot of care once they are grown. If you want a short-season harvest, a determinate tomato is for you. However, if you would like to grow indeterminate tomatoes that will bear more fruit over a longer season, then indeterminate varieties might be better for you.
Tomato plants produce flowers at the tips of their branches, or peduncles. Some gardeners prefer to harvest the flower buds while others leave the flower buds to finish growing. However, the flowers that form at a determinate tomato plant’s tip do not have as much flavor as those from indeterminate plants, so most gardeners remove them.
Because determinate tomato plants stop flowering after they bear fruit, it is possible to place the entire plant in one container and still get a harvest. Determinate tomatoes can be grown in pots because they are designed for containers.
Indeterminate tomato plants may be grown in pots, but they are not as compact and rounded as their determinate cousins. Indeterminate tomatoes are more suitable for growing in the ground because of their sprawling growth pattern.
Indeterminates also produce fruit throughout the season, making them a good choice for gardeners limited on space. If you want to grow tomatoes longer because your growing season is long, you can space out indeterminate varieties and still get an extended harvest if you thin out some of the plants.
What are the determinate plants?
Determinate plants have a defined growth pattern, flowers are produced at the end of the stem and leafy branches that form.
What are the indeterminate plants?
Indeterminate plants are those with a non-defined growth pattern, they continue to grow in leafy shoots and flower production can be carried on all year round.
Do Determinate tomatoes stop producing?
No. Determinate tomatoes keep on producing as long as they have an adequate water supply and support from trellis. There is a misconception that determinate plants only produce in the early part of the season and then stop.
Will my Indeterminate tomatoes set fruit without pruning?
No. Indeterminates need to be pruned if they are not controlled by other means, such as staking or caging.
Will Indeterminate tomatoes produce fruit for a long time?
Yes, indeterminates are capable of producing fruit for a long period if not pruned.
Will my determinate tomato stop flowering?
Determinates do not carry on flowering once they set fruit. However, some determinates put out side shoots and flower, but these are removed so as to not interfere with the growing and fruiting of the main plant. Determinate tomatoes stop flowering at the point where they have exhausted all their water.
Which are better plants to grow in containers; Determinate or Indeterminate?
Indeterminate tomato plants can be grown in containers and produce fruit over a long period. However, determinates can produce large, tasty fruit or vegetables in the space of a few short weeks. It depends on what you want out of your gardening. If you want to be able to harvest the entire crop at once, determinates are good for you.
If you want a short season harvest from your garden, use determinate tomatoes. If you are able to grow your tomatoes for a longer period, indeterminates are good for you. Indeterminates produce less fruit over a shorter period of time.
