Causes and Solutions for Root Rot in Hydroponic Spider Plants

  Spider plant lovers always like to pinch off a few leaves and stems and grow them in water. Careful growers notice that before long, the roots of the spider plant begin to rot. So, what should you do if the roots of a hydroponic spider plant rot?

  If the roots of the spider plant have already rotted in the water, it is best to first clean the container and the roots of the spider plant, cut off all the rotted roots, and soak them in a 500-times dilution of potassium permanganate solution for 20 minutes to disinfect; the container should also be disinfected. Place the disinfected spider plant in a cool, shaded spot first, and after about 2 days cultivate it again in clean water. A semi-shaded or indirectly lit environment is best; in a fully shaded spot it will gradually weaken. In winter it needs to be placed in a spot with plenty of sunlight.

  If the temperature is 20-25°C, change the water once every 3 days; when below 20°C, it is best to change the water about once every 5 days; when above 25°C, change the water once every 1-2 days. And each time you change the water, rinse the sticky mucus off the roots with tap water. Managed this way, it is guaranteed to grow well. Note: do not fertilize within 1 month; afterwards you can apply a little to help it recover. Below are several situations that cause root rot in hydroponic spider plants and how to handle them.

  1. Low temperature

  Cause:

  The roots of the spider plant are very sensitive, especially in hydroponics; the temperature of the environment and the water is very important. When the water temperature differs greatly from room temperature, or the newly added water is too cold, root growth will be affected and root rot may occur.

  Solution:

  With hydroponic spider plants, root rot is much simpler to deal with. Check the root growth regularly and cut off rotted roots promptly. When changing the water, make sure the water temperature is close to room temperature and avoid water that is too cold or too hot.

  2. Excess nutrients

  Cause:

  Many people love using nutrient solution when caring for hydroponic plants. If used in excess, it will instead affect the growth of the spider plant. The nutrient solution in hydroponics has a low dissolved oxygen content, causing the plant roots to die from lack of oxygen and gradually rot.

  Solution:

  Change the water frequently, and each time you change the water, clean the container walls and the spider plant roots. Nutrient solution can be used, but be careful not to overdo it; use it according to the instructions.

  After the spider plant's roots rot, just grow it in clean water only, and once the roots adapt to the environment and grow new roots, then add nutrient solution.

  3. Poor water quality, high water level

  Cause:

  This water quality issue needs to be explained properly. If there are leftover plant fragments or residual substrate, nutrient solution sediment, etc. in the water that cause the water quality to deteriorate, root rot is very likely to occur. In addition, the water level is also a key factor in root rot.

  Solution:

  Leave half of the spider plant's roots in the nutrient solution and expose the other half to the air. This can greatly increase the oxygen supply to the plant's roots and effectively reduce the occurrence of root rot.

  Change the water promptly to keep the water clean. For tap water at home, let it sit for a day before use.
