Signs Of An Over-Watered Tomato Plant | How To Fix
Overwatering tomatoes can kill plants. Too much water leads to root rot and spreads fungal spores.
In this article, I will share 7 signs that you are over-watering your tomato plants. However, first let’s discuss just how much water you should be giving your tomatoes.
How Often Should You Water Tomatoes?
Tomatoes like evenly moist, well-drained soil. The soil should never stay soaked long. This suffocates roots by pushing out air. To water right, keep soil moist but ensure drainage all season.
1. Drooping Leaves
Wilting leaves can be a sign of both over-watering and thirst in tomato plants, leading to confusion.
To determine if your tomato plant needs water, check the soil moisture content. Dig around the base of the plant about 2-3 inches deep. If the soil is dry, then the issue is lack of water. If the soil is moist, wait until it dries out before watering.
Drooping tomato leaves indicate a problem, but it’s important to investigate further before assuming it’s due to over-watering.
2. Chlorosis (Yellowing Leaves)
Another symptom to be aware of is discolored leaves, particularly yellowing or chlorosis. While yellow leaves can indicate various issues, over-watering can certainly contribute to this problem.
Before jumping to conclusions, it is important to consider a few other potential causes if you notice yellowing leaves on your tomato plant.
- If you are growing tomatoes in containers, your plants may require nitrogen as they could be experiencing nutrient deficiency.
- Plant leaves naturally die as they age. As they become less efficient, the plant decides they are no longer necessary and they will turn yellow and drop off. This is a normal process and there is no cause for concern.
- If you notice yellowing spots or spreading, it could indicate the presence of disease.
If the aforementioned causes can be eliminated as possibilities, yellow leaves may be a result of excessive watering. When roots are deprived of oxygen, certain areas of the plant may turn yellow and wither.
3. Adventitious Roots On Stems
Tomatoes have the ability to grow roots along any part of their stems, allowing them to re-root when they come in contact with soil. This makes cloning tomato plants extremely simple.
If you observe roots along the stem of your tomatoes, it could indicate overwatering. Moisture can cause tomatoes to develop these extra roots.
The presence of excessive humidity or over-watering could potentially lead to the formation of these roots. In environments with high humidity, moisture in the air can contribute to this phenomenon.
If the soil is excessively moist, roots are likely to develop near the soil. It is recommended to consider bottom pruning to improve airflow and to consider reducing watering.
4. Root Rot
Root rot is a symptom of over-watering in tomato plants. When the roots are constantly submerged in water, they are unable to get enough oxygen, leading to rotting.
Root rot is a significant concern that can ultimately result in the death of a plant.
Root rot can be caused by over-watering as well as diseases like phytophthora root rot. However, proper water management is the most effective way to prevent root rot diseases.
Tomatoes can be saved from root rot by re-rooting the plants along the main stem, which provides a new connection to the soil and is a way of propagating.
5. Disease
Disease is a common challenge when growing tomatoes, so we take various precautions to prevent it, such as planting resistant varieties and practicing bottom pruning.
If your plants are diseased, there are various potential causes. However, excessive watering of tomatoes can certainly be a contributing factor.
Fungal and bacterial infections that affect tomatoes thrive in humid and wet environments. Consequently, excessive watering increases the likelihood of pathogenic spores infecting your plants.
Additionally, water is a common medium for spore replication and spreading between plants. Therefore, if your plant leaves are frequently wet or if you touch your plants after watering them, it is possible that you could be unintentionally spreading disease.
6. Dying Leaves
If a tomato plant is showing signs of decline, it is possible to revive it by making adjustments to its watering schedule and providing proper care.
If the tomato plants have reached this stage, there may already be some damage. It is advisable to remove any dead or dying parts of the plants to promote new and healthy growth.
Some leaves will naturally die as they age. This process typically begins at the lower part of the plant where the oldest leaves are located.
7. Curling Leaves
Lastly, curling or deformed leaves may indicate over-watering in tomato plants. Excessive water in the soil can cause leaf deformation and abnormal stem bending.
Another common reason for curled leaves is excessive heat. Tomato plants naturally curl their leaves as a protective measure against high temperatures. If the weather has been hot in your area, this is likely the cause.
