How to keep office cactus? How often does cactus water?

Many friends know that cactus grows in the desert, and its tenacious vitality is admired by people. But why are cactus raised by many people in the office easy to be raised? How often is cactus watered the best? Don't water it with cheap hands!

Does cactus need watering? The answer is yes. Cactus afraid of the wet, rotting roots and rotten meat, so should not be dry and not watered, two centimeters below the surface of the soil as the standard. If the soil is fine, the number of times shall be reduced appropriately, and if the soil is coarse, the number of times shall be increased appropriately. If it is kept in the house for a long time, pay attention to ventilation after watering, and put it in the house when the soil surface is dry after water absorption.

How to water the cactus?

1. Spring and Autumn: This is usually watered once every two weeks, because the weather is clear and the climate is warm in spring, but the water content in the air is not low. Cactus can absorb the water and nutrients in the air through its leaves (thorns), so watering once every two weeks is enough, and excessive water will be drowned.

2. Summer: in summer, the weather is hot, the climate is dry, and the water in the air is less, so it is usually watered once a week. If the climate is very dry, it can be watered once every 5-6 days. If it is an office potted cactus growing in an air-conditioned environment, it is better to water it once every 10 days or so.

3. Winter: it's cold and foggy in the air, so the cactus is not short of water at this time, but the soil will still have water evaporation. In order to ensure that the root system has enough water, it's usually watered once in two months, and twice in one winter. Special reminder, pay attention to the cactus in winter to keep warm and cold. It is not afraid of cold and hot plants yo!

Cactus has always been regarded as a "lazy plant", but many flower friends asked how often cactus should be watered. Some flower friends thought cactus could not be watered for a long time, which was actually wrong. If you want to raise cactus well, it is very important to water it. The frequency of cactus watering should be determined by the ball, the weather, and the maintenance conditions.

In short, cactus watering can't be calculated according to the day. We should judge whether it's time to water according to the actual situation. See the following analysis.

1. If the soil is not dry, it will be poured thoroughly.

Cactus watering taboo for a long time to make the pot soil wet, easy rotten ball, water once can wait for the soil to dry, water again next time, flower friends do. Can rest assured that even if the soil dried cactus will not die, so watering will not be late.

2. No watering in winter and less in summer.

In winter, the temperature drops, the water evaporates slowly, and the cactus is also in a state of dormancy or slow growth. The demand for water is not high, so we choose not to water or less in winter, but there are also special cases. For example, in the northern indoor areas with heating, the cactus is placed indoors, the indoor air is dry and the temperature is high, so the watering can still be the same as in summer The water volatilizes faster, so the watering frequency can be increased.

3. Watering principle in other cases.

The ball just bought home will not be watered; the ball just suntanned will not be watered; the ball in early spring will not be watered; the ball just changed basin and new cutting will not be watered.

Flower friends are more likely to make mistakes in these situations. We must pay attention to them. Here are some common knowledge about cactus watering:

1. Do not spray water, but water from the root. Otherwise, the ball will easily rot if the water falls on the ball.

2. Water the ball in summer and winter, spring and autumn, summer and winter. At that time, because the temperature is too high and too low, water the ball carefully.

In winter, for most cacti, they enter their dormancy period, during which, they should be basically dry. Generally, after watering in the middle and late October, it is not necessary to water until the next Qingming. Spring and autumn season, the temperature is appropriate, at this time, cactus into the vigorous growth period, watering can not be ignored, 3-5 days to water, and pay attention to fertilization.

Cactus management is extensive and easy to cultivate. Therefore, cactus should not be watered too much, otherwise it will have the opposite effect. How often should cactus be watered? Generally speaking, it can be watered every half a month. Too often watering is not conducive to cactus growth, and do not wet cactus roots when watering.
