When selecting tomato varieties, the most critical decision beyond fruit type is the growing habit. Tomatoes generally fall into two categories: cordon (indeterminate) and bush (determinate). The primary difference lies in how the plant grows and how it must be managed to produce a successful harvest. Cordon tomatoes are vigorous, tall plants that continue to grow and produce fruit throughout the season unless stopped by the gardener. Bush tomatoes are naturally compact, reaching a predetermined size before focusing their energy on ripening a concentrated crop of fruit.

Identifying the growth habits
Understanding the botanical distinction between these two habits is essential for planning your garden layout and purchasing the correct supports.
Cordon (Indeterminate) tomatoes
Cordon tomatoes are characterized by their vertical, vigorous growth. They do not have a natural stopping point and will continue to extend their main stem as long as conditions allow. Because they grow upwards, they occupy very little ground space, making them useful where height is available; allow adequate spacing and airflow. However, they require significant vertical support and active maintenance to prevent them from becoming an unmanageable mass of foliage.
Bush (Determinate) tomatoes
Bush tomatoes are more compact and grow to a specific height and width. Once the plant reaches its genetic limit, it stops growing vegetatively and puts all its resources into the fruit. This makes them the easiest type to grow, as they require minimal maintenance. Some specialized bush varieties are trailing types, which are suitable for hanging baskets or window boxes where the stems can cascade over the edges.
Comparing maintenance and pruning
The level of effort required for each habit differs significantly, particularly regarding the management of side-shoots.
Pruning cordon tomatoes
To ensure a cordon tomato produces high-quality fruit rather than excessive leaves, it is commonly trained as a single-stemmed plant. This involves the regular removal of side-shoots—the small stems that sprout from the joint between the leaf and the main stem. If these are not pinched out or snapped off, the plant becomes a sprawling shrub that is difficult to support and can become crowded, with fruit ripening less evenly.
Additionally, cordon plants require a “topping” process. Once the plant has set a specific number of fruit trusses—typically seven in a greenhouse or four outdoors—the growing tip of the main stem should be removed. This is usually done two leaves above the top truss to ensure the plant directs its remaining energy into ripening the existing fruit.
Managing bush tomatoes
Bush tomatoes should not be pruned in the same way as cordons. Their side-shoots must be left intact to allow the plant to develop its natural shape and full crop. While they do not need side-shoot removal, they may require structural support. As the fruit matures and becomes heavy, the branches may droop or risk snapping. In these cases, short vertical canes can be inserted and the shoots tied in loosely to prevent breakage.
Space and support requirements
The physical footprint of your plants will dictate which habit is most appropriate for your specific growing area.
Vertical vs horizontal space
Cordon tomatoes are the superior choice for narrow spaces or greenhouse borders because they grow vertically. However, they require tall, sturdy supports such as bamboo canes or vertical strings anchored to the greenhouse roof. Because tomatoes do not naturally cling to supports, they must be tied in by hand as they grow.
Bush tomatoes require more horizontal space but very little vertical height. They are ideal for large patio containers, troughs, and window boxes. Because they are compact, they are less likely to become top-heavy than a tall cordon plant in a pot, though they still benefit from light support during the peak of fruiting.
Ripening speeds and harvest patterns
The timing of your harvest varies between the two habits, as well as the type of fruit grown.
Harvesting patterns
Bush tomatoes generally produce their fruit in a more concentrated burst. Because the plant stops growing once the flowers are set, the fruit tends to ripen more uniformly. Cordon tomatoes, by contrast, produce fruit continuously over a longer period, provided the plant is maintained and the weather remains favourable.
Speed to maturity
Bush varieties are often speedier to mature than cordon varieties. This is particularly true for cherry-fruited bush types, which can be ready for harvest as early as July. Choose a variety with an early-cropping description rather than judging maturity by colour; orange fruit does not inherently ripen sooner than red fruit.
Choosing the right habit for your location
The final decision should be based on your environment and the amount of time you can dedicate to the plants.
When to choose cordon tomatoes
- Greenhouse growing: When you want to maximize vertical space and produce a large, prolonged crop.
- High-maintenance preference: If you enjoy the process of pruning and training plants.
- Limited ground space: When you have a narrow border but plenty of height.
When to choose bush tomatoes
- Patio or balcony gardening: When using troughs, window boxes, or hanging baskets.
- Low-maintenance preference: If you want less pruning, while still providing regular watering, feeding and checks.
- Early harvests: When an early-cropping bush variety suits your space and season.
Summary of distinctions
| Feature | Cordon (Indeterminate) | Bush (Determinate) |
|---|---|---|
| Growth Habit | Tall, vertical, continuous | Compact, bushy, limited height |
| Pruning | Side-shoots removed; topped | No side-shoot removal |
| Support | Tall canes or vertical strings | Minimal or short support canes |
| Harvest | Prolonged over the season | Concentrated burst |
| Best Location | Greenhouses, narrow borders | Patios, containers, baskets |

- Bamboo canes: Essential for supporting the vertical growth of cordon tomatoes. Ensure the length is sufficient for the variety's expected height, typically 1.5m to 2m for cordons. Search Amazon for Bamboo canes.
- Garden twine: Used to tie cordon tomatoes to their supports at regular intervals. Check for biodegradable options to avoid removing plastic ties from the soil at the end of the season. Search Amazon for Garden twine.
