The latest culture method of cactus

Cactus is a common kind of family flowers, as long as it is properly maintained, it not only grows fast, but also grows brightly and blooms luxuriantly. Cactus like warmth, afraid of cold, room temperature below 2 degrees Celsius will be frozen to death, winter should move indoors. The amount of watering is mainly determined by air temperature, light time, wind and many other factors. if the air temperature is low, the cactus grows slowly and consumes less water, watering should be controlled. the lower the temperature, the more necessary to keep the basin soil dry. Adult balls are more resistant to drought than small balls.

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.

Light

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.

Basin 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.

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.

Change the basin

Potted cactus flowers, it is appropriate to use strong breathable tile basin, basin bottom cushion broken brick particles as drainage layer. The palm root plexus is small, the planting basin should not be too large, and the basin diameter should be similar to the plant diameter, beautiful and harmonious. 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.

Watering

The time of watering is early morning in summer, sunny weather in winter, morning and evening in spring and autumn. In general, do not sprinkle water from the top, or there will be ugly spots on the sphere over a long period of time. In general, watering must be fully watered, so the soil must be often loosened to make the basin soil easily and evenly absorb enough water.

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.

Winter dormancy should be controlled watering, in order to keep the basin soil not too dry, the lower the temperature, the more 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 amount of water will gradually increase.

Fertilizer application

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. Pay attention to the control of fertilizer and water after autumn, usually once a month, until early October

Stop getting fat. If the fertilizer is not controlled. let the cactus continue to grow, and the tender sphere is vulnerable to freezing when it overwinters. Fertilizer should be careful not to touch the ball, if there should be extreme spray washing with water.

The base fertilizer should be mixed with appropriate amount in the culture soil before going into the basin or changing the basin, such as fully mature oil meal, bone meal, chicken pigeon dung, etc., and pile it for a period of time to be fully integrated with the soil. Topdressing should be based on plant growth, but in the spring and autumn season, fully mature feather hoof horn or oil meal fertilizer and water should be applied every two weeks. Note that the root osmotic pressure of palm flowers is very low, fertilizer and water must be diluted and thin, do not be heavy and fertiliser. It can also be applied alternately with 0.1% urea and 0.2% potassium dihydrogen phosphate mixed solution, and the amount of fertilizer and water is applied to cover the basin soil surface. Household farming, such as basin soil, has a high content of organic matter, which can be used alone to keep the environment clean. No fertilizer during high temperature, extreme heat and low temperature dormancy.
