Is it good to put a cactus in the bedroom? The latest answer is here

The cactus is commonly known as grass ball, Changsheng wan, short-haired wan, etc. It is a perennial succulent herbaceous plant of the Cactaceae family. It usually blooms in the early morning or evening, lasting from a few hours to one day. Its stems, leaves and flowers all have high ornamental value, and it is also an artistic fine product among hydroponic flowers. It also has the effects of absorbing electromagnetic radiation, adsorbing dust and purifying the air. Now let us take a look at whether it is good to put a cactus in the bedroom!

Is it good to put a cactus in the bedroom?

1. Environmental protection effect: The cactus has an anti-radiation function. In life and work, people often ask, does the cactus protect against radiation? The answer is yes. The cactus opens its stomata at night and can release a large amount of oxygen while absorbing carbon dioxide. Placing a cactus near electrical appliances at home or in the office can effectively reduce the electromagnetic radiation pollution produced by various electrical and electronic products and increase the concentration of negative ions in indoor air. Therefore, placing a cactus plant near electrical appliances at home or in the office can help the human body reduce as much as possible the radiation released by computers.

2. Natural oxygen bar: Most plants carry out photosynthesis during the day, absorbing carbon dioxide and releasing oxygen. At night they carry out respiration, absorbing oxygen and releasing carbon dioxide. Some plants are the opposite. For example, the cactus releases carbon dioxide during the day, while at night it absorbs carbon dioxide and releases oxygen. In this way, placing a cactus in the bedroom at night can supplement oxygen and help sleep. Do not underestimate the cactus; it is also an expert at adsorbing dust! Placing a cactus indoors, especially a hydroponic cactus (because a hydroponic cactus is cleaner and more environmentally friendly), can purify the air.

How to care for a cactus

1. Temperature: The cactus likes high temperatures and a dry environment. In winter, the room temperature during the day should be kept above 20°C, and the nighttime temperature should not be lower than 10°C. If the temperature is too low, the root system is prone to rot, but if the temperature is too high, scale insect damage is likely to occur.

2. Light: The cactus requires plenty of sunlight, but in summer it must not be exposed to strong sunlight and needs appropriate shading. For indoor cultivation, lamplight can be used to promote healthy growth.

3. Soil: The cactus is suitable for growing in well-drained sandy loam. For indoor cultivation, artificial potting soil is mostly used, usually prepared by mixing half peat soil and half fine sand. It can also be planted in a potting soil made by mixing crushed pine needles with fine sand.

4. Watering: The cactus requires a dry environment and is afraid of water accumulating in the pot soil. Generally, the pot soil should be kept “dry and wet alternately”. It is best to water with water that has been left to stand. Be sure to water thoroughly.

5. Fertilizing: When changing the pot soil for a cactus, apply a small amount of base fertilizer at the bottom of the pot, such as horseshoe slices, soybean cake or sesame paste residue. During the growing season, water once every half month with fermented organic liquid fertilizer (a concentration of 20% is appropriate). Never let the fertilizer concentration become too high.

Notes on growing a cactus

1. Cacti grown at home are generally potted. The growing soil uses 6 parts leaf mold, plus 4 parts sand and 2 parts rice husk ash. If a little bone meal is added, it is even better. Stir evenly and then plant.

2. In spring and summer, when the cactus begins to grow, apply fertilizer once every half month, preferably a mixed fertilizer of nitrogen, phosphorus and potassium. In addition, provide appropriate shade and never expose it to the scorching sun.

3. In winter, move the potted cactus indoors. It can overwinter safely as long as the room temperature is above 5°C. At this time, a home potted cactus can be placed in a glass tank indoors to keep warm through the winter, or it can be covered with a double-layer plastic bag to keep warm through the winter. In winter, the cactus is in a dormant period, and the pot soil should be relatively dry; otherwise, the roots are prone to rot.

4. The cactus is not suitable for too much watering, otherwise the roots will rot. In spring and summer, it is best to water once every one to two months; in autumn and winter, once every two to three months is enough.

5. Place it at home in a place where young children cannot reach it.
