What Causes Orchid Root Rot
Let's share the knowledge about what causes orchid root rot, let's get to know it together.
What Causes Orchid Root Rot
Orchids need plenty of light to grow. Without sunlight, the evaporation of water will be slower, and the roots will be unable to breathe, leading to root rot. If you overwater orchids for a long time, waterlogging will occur in the potting soil, causing the roots to rot.
Reasons for Orchid Root Rot
1. Insufficient lighting: Orchids require ample light to grow. If there is not enough light for a long time, it will affect their photosynthesis. Without sunlight, water evaporates more slowly, and the roots cannot breathe, leading to root rot.
2. Overwatering: If the amount of watering is not controlled, overwatering orchids for a long time will cause waterlogging in the potting soil, leading to root rot.
3. Over-fertilization: If too much fertilizer is applied during the orchid's growing period, the roots cannot absorb all the fertilizer, leading to root damage and subsequent rot.
Dealing with Orchid Root Rot
1. First, during maintenance, we can allow orchids to receive at least 4 hours of light per day, but be careful not to expose them to direct sunlight. It is also appropriate to enhance ventilation to help the accumulated water in the soil evaporate quickly.
2. When root rot is detected, stop or reduce watering the orchid immediately. Only water when the potting soil has dried out, and stop watering when the temperature is too low.
3. Of course, if root rot is detected during maintenance, it is necessary to reduce the amount of fertilizer appropriately. When applying organic fertilizer, avoid getting it close to the orchid's roots. If too much fertilizer is applied accidentally, increase the frequency of watering to dilute the excess nutrients with water, allowing the fertilizer to be flushed out faster.
Preventing Orchid Root Rot
When planting orchids, add陶粒 (陶粒 = ceramsite) and stones to the decomposed leaf soil and peat soil to increase the soil's aeration and drainage. When watering orchids, also pay attention to the amount of water, maintaining the soil to be dry and then wet.
