How to raise cactus and how to enter winter

Overwintering management in cactus cultivation is very important. Poor management of overwintering not only affects the growth of cactus in the coming year, but also often leads to plant decay and even death. Next, let's go and see how the cactus enters the winter.

The culture method of cactus:

1, spring, autumn and winter these three seasons, the sun is not strong, the temperature is not high, cactus leaf water evaporation is less, so watering can not be too much. Just the right amount, the temperature will rise in summer, watering will increase a little bit, but not too often, spray some water to the cactus, always keep the place where the cactus is put, the air is moist and not dry. You can spray a small amount of water with a spray can at any time.

2. Cactus likes to live in soil with adequate nutrition and loose air, and it is usually best to cultivate the soil specially. Vermiculite: fine sand: humus = 2:2:1, and then stir evenly. The culture soil should be barely clumped by hand, and loose sand is better. This kind of soil is more suitable for cactus growth.

3. In terms of watering, no matter what season it is watered, it should be thoroughly watered. "if you don't dry, you will not water thoroughly." that is, you don't have to water frequently, but once watering will make every part of the soil drenched, and you can't water it only to the middle waist. It will rot easily.

4. Spring, summer and autumn is the cactus growing season. In winter, plants will enter a dormant state and stop growing. At this stage, watering should not be too much, so that the potted soil can be moist. Plants absorb less water in winter, and too much watering is easy to rot their roots. Cactus is more like the light, take it out to bask in. Can not be in a hidden place for a long time, but it is not suitable for long-term exposure. The sun shines best in the morning.

In the place of origin, the fleshy stem of most cactus can not only be used as feed for livestock, but also for food. The tender stem of some cactus is sold on the market as a vegetable, salted and eaten as a cold dish, crisp and refreshing; cooked, delicious, if fried with sugar, can be processed into candied fruit, not only unique flavor, but also quite nutritious.

Recently, it has been found that the mucus in the succulent stem of cactus has a good effect on water purification, and it is a purifying agent for field workers to use natural water on the spot. The juice of some cactus fruits has long been used as a safe edible red pigment. There is a kind of cactus called cochineal cactus, which can be used as a host to cultivate cochineal insects and extract precious natural red dyes.

Most cacti have distinctive biological characteristics: stomata are closed during the day to reduce evaporation of water in the body, and stomata are not opened until night to absorb carbon dioxide and produce oxygen. At the same time, the carbon dioxide produced during breathing is absorbed and digested by itself. If the cactus is placed indoors at night, it can purify the air and is beneficial to human health.

The overwintering management of cactus is very different between the north and the south. In the south, where there is no frost and the frost period is very short, you can spend the winter in the open air or move indoors for a short time, as long as you pay attention to controlling watering to prevent decay. The situation is different in the north, where many cacti slow down after mid-August and should move indoors in late September and outdoors in mid-May of the following year.

Cactus overwinters in the north, not fertilizing, changing pots and grafting. During dormancy, you should still bask in the sun and control watering. The lower the temperature, the more you should keep the basin soil dry.
