Pests and Diseases - ROOT ROT

Often a result of over-watering

Symptoms
The plant fails to thrive. Leaves become limp and yellow and eventually fall off. On lifting the root ball from the pot it is obviously water-logged and the roots are a dark brown colour. If they are already quite rotten they may fall off at a touch.

Treatment
A plant which has reached this sorry state may have lost too many roots to recover. It may be possible to save it by using the same measures as for over-watering. It will be necessary to produce enough healthy white roots to sustain the plant before it is likely to recover.

Root rot is the result of poor greenhouse management and can often be due to cramped roots and the need for re-potting in a larger size pot, but over-watering is the main culprit. Never leave a fuchsia standing in a saucer of water after it has soaked up its immediate requirements.
