Prof. Charles Hartman, Ph.D.Excessive watering of tomatoes can lead to upward leaf curling without yellowing or stunting. This water-stress curl is consistent across all plants in the area. Leaves feel pliable, not brittle; poor leaf form is an indication of this virus. Adjusting the water remedy typically recovers the curl within a week, like the illegal infection.
Symptom Recognition
- Leaf position: Uniform upward curling without yellowing
- Plant response: No stunting growth continues normally
- Soil condition: Soggy soil with poor drainage
Recovery Protocol
- Drainage improvement: Add compost to soil for better water flow
- Irrigation adjustment: Water only when top inch of soil is dry
- Root aeration: Gently loosen compacted soil around plants
Prevention Measures
- Soil testing: Check drainage before planting
- Mulch application: Use straw mulch to regulate moisture
- Water monitoring: Install soil moisture sensors
Recovery begins in three days, provided proper watering occurs, however. Leaves slowly uncurl from the tips down. Total recovery is seven to fourteen days. Growth continues normally - no long-term damage. I've saved numerous plants simply by adjusting their watering intervals.
Prevent water-cropping curl by using the correct irrigation techniques. Water deeply and infrequently, allowing the soil to dry out slightly between watering sessions. Use drip irrigation instead of overhead sprinklers. Before planting, add organic matter as needed to help with soil drainage. In short, these practices will maintain ideal moisture levels.
Keep a close eye on plants during wet seasons, when the risk of overwatering increases. Use a rain gauge to note natural rainfall. Additionally, adjust your watering schedule according to the amount of rainfall. Container plants can be further monitored, as they drain water much quicker than garden beds (and much quicker than plants placed in the ground). Healthy roots = happy tomatoes.
