1. **Inspect the Bumps**: Examine the size, shape, and color of the bumps. This can help determine if they’re caused by pests, diseases, or environmental factors.
2. **Check for Pests**: Look for signs of insect infestations, such as aphids or spider mites, which can cause galls.
3. **Assess Environmental Conditions**: Ensure your tomatoes are planted in well-draining soil and receiving adequate water and sunlight, as stress can lead to abnormal growths.
4. **Identify Diseases**: Some galls may indicate disease, such as bacterial or fungal infections. Research symptoms to see if your plants match any known issues.
5. **Prune Affected Areas**: If the bumps are localized, consider pruning them to prevent the spread of any potential disease.
6. **Use Appropriate Treatments**: Depending on the cause, apply insecticidal soap for pests or fungicides for diseases to help manage the problem.
7. **Monitor Progress**: Keep an eye on your plants after taking action. Regularly check for new growth and signs of recovery.
Understanding the cause of those weird bumps can save your tomato plants and ensure a successful growing season. Don’t let small issues turn into big problems!
