Editor / succulent plant sink

Yesterday, someone asked the chief: why is his succulent and black rot, the leaves fall off as soon as they touch them! Congratulations. You've been flipped.

Of course, it is not only this meat friend, but many meat friends may encounter black rot and the loss of leaves in the process of maintaining succulent succulent plants. In view of this situation, many meat friends do not know how to deal with it. Today, the chief will tell you that I hope it will be helpful for you to grow succulent plants.

Symptoms of black rot:

After a large number of investigations, it is found that nine times out of ten the succulent leaves of flower friends are black rot, and the specific symptoms are that they wake up and find that a lot of succulent leaves have lost a lot of leaves; the leaves fall off at the slightest touch; there is water on the fallen leaves (sometimes the leaves look normal).

These are the characteristics of black rot. In the early stage, there are no symptoms of black rot in the rhizome. It needs to be cut open to find it, and it is easier to judge in the later stage. If it is black rot that causes succulent plants to lose their leaves, then they need to be beheaded and cuttings as soon as possible, so that they may still be saved, but they will not be saved at a later stage.

Therefore, when the leaves fall off as soon as they are touched, sometimes it is a sign of succulent black rot, so it is time to throw away the black rot leaves. Generally speaking, it is basically impossible to insert the black rot leaves. Then check to see if its poles and roots have blackened. If it is too late, the black rot is really hopeless.

At the beginning, cut off the black rot with a sterilized knife, cut it as clean as possible, and then dry the wound in an astigmatic and ventilated place and put it on the basin.

Secondly, black rot is also contagious to a certain extent. If one of the meat is found to have black rot, the other meat should be isolated at this time.

Black rot generally occurs in summer, usually maintenance should pay more attention to ventilation.

An in-depth explanation of black rot

[summary in a word] once there is a place on the succulent plant that fades and becomes soft and black, it is rotten, and if it is rotten, it should be set up, carved, cut, and removed, and knives and hands should be disinfected before and after infecting other plants. in case of fungal infection, the plant should be sprayed with fungicides (such as carbendazim). The wound must be completely dry before it can be buried.

Route of transmission of black rot / rot: air, polluted flowerpots & planters

1. A description of black rot

Black rot / rot is one of the most common diseases of succulent plants, which is usually caused by fungal infection caused by too much watering or too moist culture environment.

Most succulent plants grow in desert climates and adapt to extremely dry conditions, so watering should not be overdone, and the soil should be left dry between watering.

Another reason for decay is that the soil medium is impermeable. Be sure to use a breathable drainage medium to ensure that the water accumulates in the stem for no more than a few minutes (the medium used by the author is usually completely watered as soon as it is poured down).

Some insects such as pink scale can also cause black rot / rot, especially root powder. The wounds caused by these pests when they feed on plant juices can cause fungal infections. Black rot / rot takes many forms, and it's often too late by the time you find it.

Always watch out for faded areas of plants, as well as softened, mushy stems and leaves.

There are many kinds of black rot / rot, which are briefly introduced as follows:

Crown decay: internal decay of the plant, causing the plant to fall.

Stem rot (mainly Euphorbiaceae): the rot of the stem, usually at the bottom of the stem.

Blotchy rot of stem: caused by Orange stink bugs.

Fungal rot: a brown, watery stain on the plant.

Apricot rot: occurs in branches.

Black rot: often occurs after cotton aphid or root powder infection.

two。 Notes on the treatment of black rot / rot:

Be sure to keep the utensils clean and sterile when handling black rot / rotten plants and wash your hands carefully before touching other plants.

Crown decay: cut off the infected part with a sharp knife and then insert charcoal and sulfur into the wound. The wound should be completely dry.

Neck rot: cut off the rotten part and treat the rest as a branch. Remember not to bury the wound until it is completely dry. [neck rot caused by cotton aphid / root powder]

Fungal rot: cut off the damaged parts with a clean knife and cover them with sulfur. The plants were sprayed with a mixture of benzoate and mancozeb.

3. The season of onset:

Why does black rot mostly occur in summer? why is it caused by too much watering or after rain? unexpectedly, there are still many meat friends who think that meat is hot to death.

In fact, it is very simple to understand this problem. Fusarium oxysporum is a fungus, and its brothers and sisters are mushrooms. Why is it easy to grow mushrooms after rain in summer? because it is warm and humid, the reproductive conditions reach the highest value. The most suitable growth temperature of Fusarium oxysporum is 27 to 32 degrees, so please pay more attention to it in summer.

The above is the introduction and prevention of succulent black rot. Finally, I hope everyone will not encounter the situation of succulent black rot, and the meat will grow healthily and beautifully!
