Culture methods of flowering cactus

We all know that the cactus is a green drought-tolerant plant with thorns. Generally speaking, we rarely see it bloom when we raise the cactus. In fact, it is possible for the cactus to blossom, but only if you raise it carefully and when the conditions are ripe.

Culture of cactus

The cactus is fond of high temperature and dry environment. In winter, the room temperature should be kept above 20 ℃ during the day and no less than 10 ℃ at night. Too low temperature can easily cause root rot.

The second light cactus requires plenty of sunshine, but it can not be exposed to strong light in summer and needs proper shade. Indoor cultivation, can be illuminated by light to make it grow healthily.

Three pots of pot cactus soil requires drainage, good air permeability, calcareous sandy soil (or sandy loam), which can be made of 2 parts of loam, 2 parts of rotten leaf soil, 3 parts of coarse sand, plus 1 part of limestone or old lime wall debris discarded during the demolition of old buildings, or 2 parts of loam, 2 parts of coarse sand, 1 part of broken brick, rotten leaf soil and 1 part of old lime wall debris. During cultivation, a small amount of broken masonry and tiles should be padded at the bottom of the basin to smooth drainage.

Fourth, the upper pot should be planted in early spring, and the flowerpot should not be too large, so that it can hold the sphere and have a little gap. The flowerpot is too large to be absorbed after pouring enough water, the air in the pot is impassable, and the root system is easy to rot. A few taproot species and bird feather jade, giant elephant balls, etc., require a deeper tube basin. Silver hair ball, descendant ball and other shallow root species, can use shallow ordinary flowerpots.

When changing the basin, part of the old root should be cut off. Dry for 4-5 days and then plant in the pot, the planting should not be too deep, and the root neck of the sphere should be flat with the soil surface. In order to avoid rotting roots, the newly planted cactus should not be watered, but should be sprayed 2-3 times a day. A small amount of water can be watered after half a month, and the new roots can be gradually watered after a month.

Six watering summer is the cactus growing period, with high temperature and high water demand. Must be fully watered, should be carried out in the morning and evening when the temperature is low, hot at noon, watering is easy to cause ball burns. In the hot and rainy season, watering should also be controlled properly. For those cactus with sunken tops, be careful not to pour water into the depressions so as not to cause decay, especially in the evening.

Watering should be controlled during winter dormancy to keep the basin soil from being too dry. the lower the temperature is, the more it is necessary to keep the basin soil dry. Adult big balls are more resistant to drought than seedlings. Watering in winter should be carried out on a sunny morning. With the increase of air temperature, the plant will gradually break away from dormancy, and the watering times and water quantity will gradually increase.

Seven fertilizers

Potted cactus can also be fertilized properly during the growing season, especially those grafted with trigonous arrows, more attention should be paid to fertilization. Fertilizer can be used with fully mature dilute liquid fertilizer, once every 10-15 days. After entering autumn, pay attention to control fertilizer and water, generally apply once a month, stop fertilizer in early October. If the fertilizer is not controlled. Let the cactus continue to grow, and the tender sphere is vulnerable to freezing when it overwinters. Be careful not to touch the ball when fertilizing, and spray it with water if it is touched.

Eight diseases and insect pests control

In the environment of high temperature and poor ventilation, diseases and insect pests are easy to occur. Diseases can be sprayed with carbendazim or topiramate, and pests can be killed by spraying dimethoate. No matter what kind of liquid is sprayed, it should be carried out outdoors.

Cactus is generally cultivated for 3-4 years, it can blossom when the diameter reaches 3-4 cm, but the number of flowering is generally 1-2, mostly 3-4, and it will wither after 24 hours. Cactus flowering is relatively rare, it needs to be under the careful care of its master, fertilizer, temperature and humidity conditions are fully available to bloom.
