The breeding method of cactus is actually a very complex knowledge, so let's find out the answer to how to maintain the cactus in the following article.

The real cactus is really easy to raise, no matter it is watering or using the soil, but the cactus purchased by some students looks good on the surface, but actually has no roots, mainly reflected in the small potted plants bought by the roadside and the small potted plants bought in the flower market.

Although the cactus is a succulent plant, it is more drought-tolerant and will not die completely even if it is not watered for a month. But it must be watered for it to grow healthily. Winter: watering about every 20 days, the watering time is appropriate in the afternoon when the temperature is higher. If the living room is relatively dry, foliar spraying water can be used to keep the stem green. After the whole plant enters the dormant period, it can not be watered.

Spring: with the rise of the temperature, the number of watering can be increased appropriately, the principle of watering is not dry, watering is thorough; not too much watering, nor long-term non-watering. When the temperature rises to about 20 ℃, it is suitable to water once every 7-10 days.

Summer: high temperature, large evaporation, exuberant growth, is the season of the largest water demand for edible cactus, generally every 3-5 days need to be watered, when the temperature rises to more than 30 ℃, in order to maintain stem swelling pressure, increase ornamental, it is best to spray water on cactus stem 1-2 times every morning and evening.

Autumn: gradually decreasing. Watering potted plants should also pay attention to water temperature and water quality. Water is neutral or slightly PH acidic, it is best to use tap water for two days before use. In addition, watering had better be close to the indoor temperature, and more attention should be paid to potted edible cactus in cold areas in the north.

How to raise cactus-watering and spraying

Terrestrial cactus has obvious growth period and dormant period, the growing period should be watered, the dormant period should be watered less or even no watering. For epiphytic type, if the winter temperature is kept above 12 ℃, it can be watered and sprayed all the year round; if the winter temperature is kept below 12 ℃, watering can be reduced and stopped. Water temperature should be close to soil temperature as far as possible, early (before sunrise) and late (after sunset) in summer, from 10:00 to 11:00 in winter, and directly onto basin soil, otherwise the appearance of thorns will be affected. In addition, it is necessary to sprinkle water on the ground in summer to increase air humidity.

How to raise cactus-fertilizing

Fertilization should grasp the following principles: timely, appropriate amount, depending on the object. Fertilization is carried out in spring and autumn, once every 20 days, and should be carried out in the early morning or evening on a sunny day. If the basin soil is dry, sprinkle some water on the basin soil and then apply fertilizer with a concentration of 0.05%. 0.2%, watering once the next morning, the effect is better. Terrestrial fertilization requires fertilizers rich in potassium and phosphorus and less nitrogen, while epiphytic fertilizers require more nitrogen fertilizer.

How to raise cactus?-Light.

Terrestrial type prefers plenty of sunshine, especially in winter. Generally, tall, cylindrical and flat cacti are more resistant to strong light and can be placed outdoors without sunshade in summer, while smaller spherical ones prefer semi-overcast conditions in summer, covering the top growing point of Jinzhu from June to August in summer with a circular plastic film to make all parts of the sphere grow evenly. Epiphytic cacti require semi-overcast conditions all the year round.

How to raise cactus?-temperature

The suitable temperature for cactus growth is between 20-35 ℃. The terrestrial type does not require a high temperature during the winter dormancy period, but the temperature can be maintained at 4-7 ℃ while keeping the basin soil dry. Epiphytic type, however, requires a higher temperature in winter to maintain 10-13 ℃ or higher. When the cactus reaches 30-35 ℃ in summer, the growth rate of most cacti slows down, and sometimes some kinds of stems turn yellow or burn, so it is necessary to shade the sun and sprinkle more water on the ground to lower the temperature.

How to raise cactus?-Air.

Cactus flowers are mostly native to desert open areas, with good ventilation and fresh air. Therefore, in the hot weather in midsummer, we should do a good job of ventilation and cooling in the cultivation site. The cultivation greenhouse should choose a well-ventilated environment and set up more vents such as windows and skylights to facilitate ventilation in the hot summer weather. If necessary, equipment such as exhaust fans, hair dryers or electric fans can also be installed to enhance the air circulation effect of the environment, so as to promote cactus flowers to spend the summer safely.
