The planting method of cactus

1. Temperature

The cactus likes high temperature and dry environment. In winter, the room temperature should be kept above 20 ℃ during the day and not less than 10 ℃ at night. Too low temperature can easily cause root rot.

2. Lighting

Cactus requires plenty of sunshine, but it can't be exposed to strong light in summer and needs proper shade. Indoor cultivation, can be illuminated by light to make it grow healthily.

3. Potted soil

Potted cactus soil requires drainage, good air permeability, calcareous sandy soil (or sandy loam). It 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.

4. Planting

Planting the upper pot had better be carried out in early spring, the flowerpot should not be too large, in order to accommodate the sphere and a little gap is appropriate. The flowerpot is too large to be absorbed after pouring enough water, and the air in the pot is impassable, which is easy to make the root rot. A few taproot species and bird feather jade, giant elephant balls, etc., require a deeper tube basin. Silver hair ball, offspring ball and other species with shallow roots can be used in shallow ordinary flowerpots.

5. the method of changing the basin.

When changing the basin, cut off some of the old roots. Dry for 5 days and then plant in the pot, the planting should not be too deep, it is appropriate to keep the root neck of the sphere flat with the soil surface. In order to avoid causing rotten roots, the newly planted cactus should not be watered, just spray 2Mel three times a day, water a small amount after half a month, and gradually increase watering after a month when the new roots grow.

6. Watering

Summer is the cactus growth period, with high temperature and large 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.

7. Fertilization

Potted cactus can also be fertilized properly during the growing season, especially those grafted with three-rowed arrows, more attention should be paid to fertilization. fertilizer can be fully mature dilute liquid fertilizer, once every 10 rain 15 days. After entering the autumn, pay attention to the control of fertilizer and water, generally apply once a month, and stop fertilizing 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.

8. Pest 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.
