Overwatering Signs
Overwatering is the most common cause of houseplant death. It deprives roots of oxygen and creates conditions for rot and disease.
可能原因
Watering on a Schedule Rather Than by Need
Why: Watering every X days regardless of soil moisture leads to overwatering, especially in low-light or cool conditions.
Signs to check: Soil is still moist when you water again, pot feels heavy, water sits in the saucer.
Poor Drainage Setup
Why: Pots without drainage holes, or decorative pots without inner drainage, trap water at the bottom.
Signs to check: No drainage holes, water collects in the outer pot or saucer, soil is waterlogged at the bottom.
Wrong Pot Size
Why: A pot that is too large holds excess soil moisture that the plant's roots cannot use quickly enough.
Signs to check: Pot is much larger than the root ball, soil stays wet for many days after watering.
Dense or Compacted Soil
Why: Heavy soil retains too much water and does not allow adequate oxygen to reach roots.
Signs to check: Water pools on the surface before soaking in, soil is heavy and clay-like.
检查要点
- 1Check soil moisture before watering — is it still damp?
- 2Lift the pot to feel its weight (heavy = still wet)
- 3Look for yellowing lower leaves, mushy stems, or foul smell
- 4Verify the pot has functioning drainage holes
- 5Check if the pot size is appropriate for the plant
处理方法
- Stop watering and let the soil dry out before watering again
- Always check soil moisture before watering — finger test or moisture meter
- Ensure pots have drainage holes and empty saucers after watering
- Switch to a chunkier, well-draining potting mix with perlite
- Downsize the pot if it is too large for the plant's root system
何时寻求帮助
- Mushy, foul-smelling roots (root rot has begun)
- Stem base is soft and dark
- Plant continues to decline despite stopping watering
关键要点
Water when the plant needs it, not on a fixed schedule. Check soil moisture, ensure proper drainage, and err on the side of slightly dry rather than too wet.
