How to raise a good cactus, whether to water it often and bask in the sun

Use a large pot to put the soil from the vegetable patch on the balcony. In the summer, it was very dry and watered. That's it. This kind of belongs to the careless.

Temperature and the sun don't need much water.

Want. Watering cactus balls should never be poured into the sphere, it is easy to rot and discolored (like rust) to affect the appearance and survival. The watering method varies depending on the variety. The ones that are not very expensive can even be put outdoors to grow naturally. It is necessary to prevent water damage during the rainy season in the south.

Cactus is very simple, usually watered once every 2 weeks, watered once every 5 days in 30 degrees weather, watered once every 3 days above 30 degrees, watered around the week when watering, and avoided the sun at temperatures above 33 degrees, and do not put it outdoors in winter. Common varieties are once a month in winter. Once a week in spring and autumn, adjust it according to the state of the plant, and turn in one direction with the sun every month to avoid growing crooked.

It doesn't matter if you put it in different positions in the morning and evening. But pay attention to the uniform illumination of the light. lest the phototaxis of the plant cause it to grow into an oval shape. Tropical varieties: Do not go too close to the window at night in winter to prevent frostbite.

Do cacti need total watering?

The definition of cactus is divided into narrow and broad senses, with the narrow sense referring specifically to the cactus family, and the broad sense of cactus referring to all globular or nearly globular cacti plants. Some cactus balls have a lifespan of more than 500 years and grow into giant balls with a diameter of two or three meters. If you want to raise a pot of cactus, you should mainly study carefully from several aspects such as planting material, temperature, light, and watering.

First, planting material:

The planting material of cactus is suitable for growing in slightly acidic and neutral planting materials. However, the overall requirements for the soil should have the following characteristics: loose and breathable, good drainage, no compaction, and the pH value is between the to.

In the north, I suggest that you can use slightly acidic soil for planting, the air in the north is drier, and it will not breed bacteria, the water is more alkaline, and the soil can be mixed with 1 3 (coir + humus + small particles of volcanic rock).

In the south, it is recommended that you can use neutral soil, the humid air in the south is easy to breed bacteria, and the neutral soil can avoid bacterial breeding. Flower soil can be mixed with one-third of each (honeycomb pulverized coal + humus + small particles of volcanic rock). <>

Second, temperature and light:

Cactus likes to be dry and resistant to high temperatures, and should be maintained in the form of full sunlight during daily maintenance. (Although it is resistant to negative, it grows stronger and healthier under light). When the temperature is not higher than 35 degrees Celsius, shade is not required.

When the temperature drops to 5 degrees Celsius, you can go into the house for the winter. (The varieties are different, the cold tolerance is different, and it is safer to enter the room at 5 degrees Celsius).

Third, watering:

The cactus is very drought tolerant, and there is a tree in my hometown that fell on the wall, although it has not been specially watered for ten years, and it does not look good, but the growth is OK, and it affects survival. It can be seen that the drought tolerance of cactus is strong. Watering potted cacti is based on the dryness of the shallow soil.

In general, the topsoil is dry, and watering is extended by about 10 days. However, the time can be appropriately shortened in spring and winter, and the watering time can be shortened in summer and autumn. <>

Fourth, fertilization:

Cacti do not require much nutrients, but if you master the method of applying thin fertilizer frequently, you can grow faster and stronger. Generally, it is recommended to use organic fertilizer for fertilization, and once a month, the "cooked sheep manure ball" is shallow buried in the shallow surface layer of the flower soil by loosening the soil.

From spring to autumn, as long as the temperature is within the suitable growth range, about 16 to 32 degrees Celsius, you can supplement the use of organic fertilizer water once a month to increase nutrients and promote growth.

The flowering period of cactus varies according to different varieties, and in the first month of flowering, you can use "potassium dihydrogen phosphate" mixed with water about 1200 times, spray wet the fleshy stems, and water the flower soil at the same time, which can promote more flowering of cactus.

Summary: The above four points are the basic methods for maintaining cactus. When winter comes, the plants will enter the dormant period, and at this juncture, it is necessary to reduce the frequency of watering and stop fertilizing.

The soil in the pot is kept not too dry. If the temperature is persistently too low, do not water or water less.

The amount of watering can be determined according to the growth state of cactus plants: during the vigorous growth period, the potting soil should be kept moist, and there should be no lack of water, but no water should be accumulated; When the temperature is low and the growth is slow, the amount of watering should also be reduced; Watering should be stopped during the dormant period; Plants with aging roots should be watered sparingly.

Appropriate watering according to soil quality: sandy soil with poor water retention performance can be watered appropriately; The culture soil with good water retention performance should not be watered too much, and after a watering, it should be watered only when the potting soil is close to dry.

Watering according to climate, environment and other conditions: watering should be moderated in the rainy season or when the air humidity is high; In dry weather, the potting soil should be kept moist; The film cover with good moisturizing performance should be watered less; Open-air cultivation can be properly watered with more water.

The best time for watering is in the evening or morning.

1. In spring and autumn, the cactus is usually watered once every two weeks, because the spring weather is bright and the climate is warm, but the moisture content in the air is not low, and the cactus can absorb the moisture and nutrients in the air through its leaves (thorns), so watering once every two weeks is enough, and excessive will be drowned. 2. In summer, the weather is hot, the climate is dry, and the moisture in the air is also less, so the cactus is generally watered once a week, and the climate is dry and can be watered once in 5-6 days, if it is an office potted cactus, and grows in an air-conditioned environment, it is best to water it once in about 10 days.
