How to deal with waterlogging and root rot? How long does it take for waterlogging in the soil to cause root rot?

1. Causes of waterlogging and root rot

1. Water accumulation in the tray: When watering most plants, the principle of "water thoroughly" is followed. This can easily lead to the excess water accumulating at the bottom of the pot after watering thoroughly. This is especially true for potted plants with a tray at the bottom. If the water in the tray is not dealt with in time, it will affect the air permeability of the flowerpot, and the roots will rot over time. Excess water in the tray needs to be promptly poured out or extracted with a large syringe.

2. The gap between the base and the flower pot is too small: The gap between the base and the flower pot is too small, resulting in poor air permeability of the flower pot, and it is also easy for excessive water to accumulate, causing root rot of the plant. You can use bottle caps or small flat objects as a base to increase the air permeability of the bottom.

3. Poor soil permeability: The soil itself has poor permeability and drainage performance, which can easily cause serious water accumulation in the pot and rot of plant roots. It is necessary to replace the flower soil in time and replant and maintain it.

4. Excessive watering: If you water too much, the plant will find it difficult to fully absorb the water, and water will easily accumulate in the pot, causing the roots of the plant to rot.

5. The pot is large and the flowers are small: If the pot is much larger than the plant, the soil in the pot will be in a state of waterlogging for a long time, causing root rot.

2. How to deal with waterlogging and root rot

1. Trim off rotten roots and replant: You need to dig out the roots and cut off the rotten parts. Then disinfect and dry the soil before replanting and maintenance. This situation applies to plants whose roots have not completely rotted, such as Clivia, orchids, etc.

2. Use branches and leaves for cuttings: When the roots cannot be regrown by pruning the roots, you can use healthy branches and leaves that are not rotten to reproduce. This method is suitable for plants such as succulents, evergreens, geraniums, and begonias.

3. How to judge waterlogging and root rot

1. Potting soil: After watering in sunny weather, wait until the next day to observe the potting soil. If the soil is dry and slightly white, the roots are normal; if the soil is still moist, the roots may have rotted. If the soil in the pot remains moist for 2-3 days, it means that most of the roots have rotted.

2. Leaf color: If the leaves of the plant lose their green luster and become grayish white, or the leaves of the plant droop and wilt, or a large number of leaves turn yellow and fall off, it means that the plant has root rot.

3. Leaf shape: If the leaves of the plant appear longitudinally wrinkled and deformed, it also indicates that the roots of the plant have rotted.
