What is Cutting Off My Tomato Plants?

Tomatoes are a popular garden crop due to their ease of growth and delicious taste. However, these plants are not immune to damage, and many gardeners have experienced the frustration of having their tomatoes cut off at the stem. If you're wondering what is cutting off your tomato plants, read on to learn about some of the most common culprits and how to prevent them.

Insects

Insects are a common cause of damage to tomato plants. Cutworms, for example, are notorious for cutting off young tomato plants at the stem. These pests are active at night and can be difficult to spot, but you can look for evidence of their presence in the form of small green pellets around the base of the plant.

Another insect that may be cutting off your tomatoes is the tomato fruitworm. This pest feeds on the fruit of the plant and can cause significant damage if left unchecked. You can prevent fruitworm damage by inspecting your plants regularly and removing any affected fruit.

Disease

Disease can also be a factor in the loss of tomato plants. One common disease that can cause the stems of the plant to wither and die is Fusarium wilt. This fungal disease is soil-borne and is spread by infected plants or soil. To prevent Fusarium wilt, rotate your crops and avoid planting tomatoes in the same spot for more than one season.

Another disease that can cause stem damage is bacterial canker. This disease causes wilting and cankers on the stem of the plant, eventually causing it to break off. To prevent bacterial canker, avoid overhead watering and practice good sanitation practices, such as removing infected plants and debris from the garden.

Environmental Factors

In addition to pests and disease, environmental factors can also contribute to stem damage in tomato plants. High winds, for example, can break off the stems of young plants. To prevent wind damage, stake or cage your plants and provide support as they grow.

Another environmental factor that can cause stem damage is temperature fluctuations. Extreme heat or cold can stress the plant and cause the stems to break off. To prevent temperature stress, plant your tomatoes in an area that receives adequate sunlight and provide shade during periods of high heat.

Conclusion

There are many factors that can contribute to the cutting off of tomato plants, including pests, disease, and environmental factors. By understanding these factors and taking steps to prevent them, you can ensure a healthy and productive tomato crop.
