Hydroponic plants always getting root rot? The cause is actually the nutrient solution

Flowers & Gardening 0 views
Anyone who has grown flowers for a while knows that growing plants can be divided into hydroponics and soil culture. Some people prefer soil culture, feeling that soil protects the plant's roots, looks more reassuring, and allows the plant to absorb nutrients more fully. Others prefer hydroponics. A large portion of these people are younger flower-growing enthusiasts. Friends who like hydroponics generally do not grow large ornamental plants; they usually choose to grow smaller plants, such as pennywort (Hydrocotyle vulgaris), which naturally grows in water, and another type of plant that can be grown both hydroponically and in soil.

To be honest, Huahua thinks hydroponic plants carry a certain risk. Because the plant's roots are placed directly into the water, root rot is very likely to occur. Once a plant develops root rot, it is actually still quite easy to deal with; it mainly depends on how you usually care for it.

So how can hydroponic plants be prevented from developing root rot? Let Huahua explain slowly.

A large part of the reason plants develop root rot is the nutrient solution. The quality of the nutrient solution directly affects the plant's roots. If the quality of the nutrient solution is poor and it contains other substances, it will cause the nutrient solution to deteriorate. Once the nutrient solution deteriorates, the plant's root rot is only a matter of time.

If the nutrient solution is too concentrated, it will burn the plant's roots and lead to root rot. So when we generally grow plants hydroponically, we should not add overly concentrated nutrient solution, and we should not let the plant's roots be completely submerged in the nutrient solution. Having all the roots submerged in the nutrient solution will cause the plant's roots to lack oxygen and make the plant develop root rot.

What should be done after discovering that a hydroponic plant has developed root rot?

Once root rot is discovered, the first thing to do is take the plant out, gently rinse it with clean water, and wash the rotted roots clean, so that we can clearly see which roots have rotted and which roots are still healthy. Then trim off the plant's rotted roots.

Wash the container holding the plant clean, then replace it with new water. After the plant has grown new roots again, you can use some nutrient solution. Some friends also ask Huahua whether tap water at home can be used directly. No, it cannot. Tap water contains a certain amount of chlorine, so we had best leave the tap water in the sun for two days before using it.

Hydroponic plants require more patience and care than soil-grown plants. Usually, try to keep the water temperature for growing them controlled at 18-25°C. If sunlight exposure is not necessary, it is best to place them in a cool, ventilated place. Friends who have the means can also add some substances to the water that can improve water quality, such as small pieces of charcoal, which can have a preservative effect.
