What causes root rot in the ZZ plant?

Improper watering

Usually, when the ZZ plant is overwatered, it leads to root rot. The ZZ plant itself likes slightly moist soil, and the potting soil should not be too dry, but if it is watered too much, it will suffer from root rot. This is because when overwatered, the potting soil is very likely to become waterlogged, making it hard for the roots to breathe and breeding large amounts of pathogens, which causes root rot.

Improper fertilizing

Improper fertilizing is also one of the causes of root rot in the ZZ plant. This is basically because when fertilizing the ZZ plant, the fertilizer is too concentrated; when the root system has not grown well, overly concentrated fertilizer will burn the roots of the ZZ plant and cause root rot.

Temperatures too low

In fact, there are also some other factors that cause root rot in the ZZ plant, such as low temperatures and cold, especially when the temperature in winter is very low, frost damage can even occur, causing the ZZ plant to freeze and then develop root rot.

Invasion by pathogens

In addition, there is the invasion of pathogens. If pathogens are accidentally introduced into the water when it rains or when watering, the plant will become infected by the pathogens, which may lead to root rot.

What to do about root rot in the ZZ plant? Causes of root rot in the ZZ plant and solutions

The ZZ plant is placed in a relatively spacious living room, study, or sitting room, with an elegant, simple style and a touch of southern charm. It is a new-generation indoor foliage plant with a graceful, neat plant shape that is world-famous, but root rot can occur during cultivation. Let's take a look below at what to do about root rot in the ZZ plant!

Growth habits of the ZZ plant

The ZZ plant likes warm, hot, slightly dry, semi-shaded environments with small annual average temperature fluctuations. It is relatively drought-tolerant, but fears cold, avoids strong direct sunlight, and fears heavy, sticky soil and waterlogging in the potting soil. If the potting soil has poor drainage and aeration, it easily causes its tubers to rot. It requires loose, fertile soil that drains well, is rich in organic matter, and is acidic to slightly acidic. It has strong sprouting ability; after cutting off the thick, large pinnate compound leaves, new leaves will quickly sprout from the top of its tubers.

Causes of root rot in the ZZ plant

1. Root rot in the ZZ plant may be caused by potting soil that is too dry. The ZZ plant likes potting soil that is slightly moist, and that is enough. It is naturally not fond of water, but if the potting soil drains poorly and the water quality becomes stagnant and foul, it can cause root rot.

2. Root rot in the ZZ plant may be caused by using relatively concentrated fertilizer before the root system has grown well. Concentrated fertilizer will scorch the root and stem area of the plant (the part close to the pot). It may also be that the potting soil is unsanitary, and when watering or raining, pathogens are splashed onto the ZZ plant.

3. Root rot in the ZZ plant is root rot disease, caused by too much watering, which leads to a shortage of air near the roots; in the damp environment, large amounts of fungi breed, ultimately forming root rot. Carbendazim or thiophanate-methyl can both be used. Penicillin cannot be used. It is best to first dig the plant out, cut off the rotted roots, soak it in a carbendazim solution for about 10 minutes, then replace the soil and replant.

What to do about root rot in the ZZ plant?

1. Generally, the cause of root rot in the ZZ plant is root rot caused by watering. The plant needs to be promptly taken out of the pot, part of the old soil shaken off, placed in a semi-shaded, cool place to dry for 1-2 days, and then replanted with new sandy loam soil. Afterward, the pot used should not be too large, and watering should not be too frequent. Water when the potting soil is 70% dry. Do not use a rigid watering interval; water flexibly.

2. If the root rot is relatively severe, it is best to shake off all the soil, then soak it in a 500-fold dilution of potassium permanganate or carbendazim solution for 5-10 minutes, then rinse it once with clean water, dry the root system, and replant.

3. You can first take the plant out of the flowerpot, cut off the rotted tubers and branches and leaves, then apply wood charcoal powder to the wounds, expose the roots and place them in a warm place. After the wounds dry, bury them in the potting soil and stop watering until spring warmth raises the temperature above 20°C, then resume normal watering, but the amount of water must be small, only keeping the potting soil slightly moist.

Root rot in the ZZ plant, how to deal with root rot in the ZZ plant

The ZZ plant is also euphemistically called the coin tree. It is a tropical cultivated plant. In home decoration, the ZZ plant is valued by many designers and homeowners. ZZ plant cultivation methods and precautions.

In addition, there is the invasion of pathogens. If pathogens are accidentally introduced into the water when it rains or when watering, the plant will become infected by the pathogens, which may lead to root rot.
Soil
Root rot in the ZZ plant can also be caused by unsuitable soil: the soil is too fertile, or the soil is too dry. Because it is a tropical plant, the soil must contain zinc and iron to ensure the ZZ plant's survival rate. Therefore, during cultivation, the selection of soil is essential.

What to do about root rot in the ZZ plant
1. Reasonable care
Reasonable care of the ZZ plant requires more effort in daily maintenance, basically including watering, fertilizing, and keeping it warm. Watering should follow the plant's growth needs; do not water too much, and also avoid waterlogging. Be sure not to fertilize too concentratedly or too frequently; light, frequent fertilizing is best, as this can prevent root rot.
2. Replanting
If the ZZ plant still shows symptoms of root rot, then it needs to be replanted. Take out the plant with root rot, remove the soil, and it is best to remove all the soil. Cut off the rotted roots, soak them in a carbendazim solution or sprinkle on some wood charcoal, place them in a shady place to dry, and then replant them in a pot. Some branches and leaves can be cut off to help it survive better. After that, be sure to care for it carefully and properly!
3. Sun exposure
After the ZZ plant develops root rot, you can apply a layer of wood charcoal powder or lime to the roots of the ZZ plant, then expose the roots to sunlight until the roots gradually harden, then water and rinse them, and then plant them in a flowerpot;
