Does the coral cactus (Euphorbia neriifolia) bloom? A detailed guide to coral cactus propagation methods

The coral cactus (Euphorbia neriifolia) is a plant that loves warmth and light, and it is currently distributed in a few areas of our country. The stems and branches of the coral cactus look very twisted, and its appearance is quite distinctive, with high ornamental value, and it is deeply loved by people. As for the question of whether it blooms, many people have different opinions, so let us find the answer together in the text below!

Does the coral cactus bloom

The coral cactus is a plant that does bloom, but for many reasons, during artificial cultivation and breeding, due to inadequate care, the coral cactus will not bloom. It is said that the flower of the coral cactus is not very attractive; its flower grows directly above the leaf eye, about a few millimeters away from the leaf eye. The flower is very small, yellow, and trumpet-shaped. However, as long as you can see the coral cactus bloom, it is also a very gratifying thing.

Coral cactus propagation methods

1. The coral cactus is propagated by cuttings. In May-June, cut fully grown stem segments as cuttings, let them dry for several days, and after the wound has slightly shrunk, insert them into plain sand. Just after inserting them into the plain sand, remember not to water. If you water immediately after inserting, the stem segments will generally rot from the bottom up. After 2-3 days, spray water again. At 20-25°C, they can take root in 40-50 days.

2. The potting soil for planting the coral cactus in a pot is prepared by mixing 3 parts garden soil, 3 parts decomposed manure soil, and 4 parts river sand. When planting, first place a layer (2 cm - 3 cm) of cinder or coarse sand particles at the bottom of the flower pot to facilitate drainage and prevent waterlogging and root rot. After potting, water thoroughly, first place it in a shady spot for one week, then move it to a place with weak light, and then gradually move it to a place with stronger light. It is drought-tolerant, so watering should be less rather than more, following the principle of watering when dry and stopping when wet.

Causes and control of Aspergillus rot in the coral cactus

1. Causes:

Aspergillus alliaceus is the main pathogen of Aspergillus rot disease, which can cause the main stem or branches of the coral cactus to rot. The pathogen attaches to soil, diseased residues, and many other substances. After overwintering, it produces conidia, which then spread through airflow, invade the coral cactus, and cause harm to it. In addition, the temperature and humidity of the potting soil should be kept continuously stable, otherwise the disease is likely to occur. Moreover, prolonged high-temperature or high-humidity environments can also lead to Aspergillus rot.

2. Control:

1. After the disease occurs, promptly remove the diseased residues, gather them and bury them deeply or burn them. In addition, 1 part 75% Daconil wettable powder mixed with 50-100 parts fine dry soil can be used as a medicinal powder scattered on the soil surface. Of course, if necessary, the potting soil can be directly replaced.

2. In the early stage of the disease, some liquids can be sprayed, such as 40% chlorothalonil suspension 500 times dilution, 50% thiophanate-methyl wettable powder 800 times dilution, or 50% benomyl wettable powder 1000 times dilution. The affected parts can be coated with medical miconazole nitrate ointment, which can effectively treat it.

How to water the coral cactus

1. Summer and autumn: Summer and autumn are the seasons when it grows most vigorously, but it is relatively drought-tolerant, so it should not be watered too much. You can follow the principle of watering thoroughly after the soil dries out; if there is rainy weather, delay watering, and do not let the soil remain moist for a long time, otherwise it is very easy to cause root rot, and in severe cases it will cause the entire plant to die. When watered too much, this plant will become leggy, which not only affects its appearance but is also unfavorable to its healthy growth.

2. Winter and spring: Its cold resistance is poor, so in winter it is generally kept indoors, and the temperature must be kept above 15°C. If the temperature drops to 12°C, it will enter a dormant period. At this time, reduce the amount of watering, or even stop watering, and keep the soil dry, then wait until the temperature gradually rises in spring before resuming normal watering. In winter, if the temperature can be controlled between 15°C and 18°C, then water once every 10 days.

The coral cactus is a variety that does bloom, it is just that blooming is rare. If you see it, you are very lucky. If you want the coral cactus to grow well during care, it must be propagated. Generally, the cutting method is used. The above text has a detailed introduction, and I hope it can be helpful to everyone.
