A brief introduction to the main points of cactus maintenance

Cactus has the function of reducing air pollution and purifying air: the stomata on its fleshy stems are closed during the day and opened at night to absorb carbon dioxide and produce oxygen, so that the concentration of negative ions in indoor air increases. So how do you raise cactus? Let's take a look at how the cactus is raised. I hope it can help the owners!

1. How to raise cacti

Sunny: Cactus likes sunny environment, but exposure will slow down the growth rate of cactus. Of course, cactus will not be sun dead, if you want cactus grow faster, it is best to find a shade for cactus when the sun is too hot.

2, should not be more water: the vast majority of cactus flowers originated in the hot and arid desert wilderness areas of South and North America, cactus roots water absorption capacity is very strong, if you water too much will make the roots fester. Some large cactus, even if not watered for a year or two will not dry to death.

3, with sand or soil: cactus like sand, so it is best to prepare sand. However, the water in the sand evaporates quickly, in order to make the cactus better growth, you can pad a layer of soil under the sand, so that you can maintain moisture to a certain extent, not watering every day.

4, fertilization is mainly phosphate fertilizer, a fertilization should not be too much, otherwise it will make the concentration of soil solution is greater than the concentration of cactus root cells, water outflow, resulting in dehydration of cactus.

5, avoid being rained: cactus is not afraid of no water, but afraid of too much water, too much water can make the root cells hypoxia death, so pay attention to rainy days do not let cactus be rained.

6, temperature: the best growth temperature of most cacti is 20--35℃. Most species prefer a larger temperature difference between day and night, which is conducive to the production and accumulation of organic substances under the conditions of less than 35℃ during the day and about 15℃ at night, thus promoting the vigorous growth of plants.

II. Key points of cactus conservation

The cactus is really good to raise, no matter watering or using soil do not have to pay attention to, but some students buy cactus is inserted, the surface looks very good, actually have no roots, mainly in the roadside purchase of small potted plants, and flower market purchase of small potted plants.

Although cacti are succulent plants, they are more drought-tolerant and will not die completely even if they are not watered in January. But for it to grow healthily, it must be watered. Winter: water every 20 days or so, watering time in the afternoon when the temperature is higher is appropriate. If the room is relatively dry, foliar spray water can be used to keep the stems green, and after the whole plant enters the dormant period, no watering can be done.

Spring: With the increase of temperature, the number of watering times can be increased appropriately. The principle of watering is not to irrigate, but to irrigate thoroughly; not to water too much, nor to water for a long time. When the temperature rises to about 20 ° C, it is generally appropriate to irrigate once every 7- 10 days.

Summer: high temperature, evaporation, vigorous growth, is the largest season of edible cactus water demand, generally every 3-5 days to water 1 time, when the temperature rises to 30℃ above, in order to maintain stem swelling pressure, increase ornamental, morning and evening every day best to spray water to cactus stem 1-2 times.

Autumn: Gradually decreasing. Potted watering also pay attention to water temperature and water quality. The water is neutral or slightly PH acidic, and it is best to use tap water for two days before use. In addition, the best watering and indoor temperature close to the northern cold areas potted edible cactus more attention.

Cactus and cactus are a relatively easy to cultivate flowers, more suitable for people who like flowers and do not have too much time to cultivate, the above is how to raise cactus introduction, if you want to know more cactus information please pay attention to related content bar.
