Prof. Martin Thorne, Ph.D.The sooner you identify signs of underwatering, the less likely you are to cause permanent damage. Signs of underwatering include wilting leaves and dry soil. However, overwatering can have similar characteristics. Identifying the problem will save your plants. I was able to revive my peace lily by discovering the difference. Plant distress signals indicate that the plant needs water.
Soil Dryness Tests
- Check 3 inches deep with finger - dusty means underwatered
- Use moisture meters for accurate root-zone readings
- Compare pot weight - light containers need immediate water
Visual Plant Signals
- Leaves curl inward or develop crispy brown edges
- Growth slows dramatically with smaller new leaves
- Stems become brittle and snap easily when bent
There are plenty of other problems to distinguish from- go ahead! Pests cause similar wilting. Disease causes spots. Examine leaves and stems very closely. Under-watered plants rebound rapidly; my aloe vera perked up within hours after soaking thoroughly. Over-watered plants may take weeks to recover.
Assist plants that have been overwatered immediately; place the pot in water for 15 minutes. For garden beds, apply water slowly for 20 minutes. Do not fertilize until plants have recovered. Remove dead leaves, but leave the green ones intact. Recovery is typically seen in 48 hours if identified quickly.
Prevent recurrence with smart timing. Change watering with temperatures. Mulch will help hold moisture. Group plants with similar needs. Drying out my herb garden since matching the watering with each plant's thirst. Staying moist kept the plants stress-free.
