What kind of soil does the cactus use to raise? Five ways to solve the yellowing problem!

Cactus, also known as Flame and Bawang Tree, is a succulent plant that can resist ultraviolet rays and purify the air. It is widely planted because of its simple planting and strong vitality. If you want to raise a good cactus, you need to choose a good soil. What kind of soil does the cactus use? What's going on when it turns yellow?

First, cactus introduction:

1. What kinds of cactus are there?

Fan cactus, segmental cactus, crab claw cactus, leaf forest cactus, spherical cactus, climbing cactus, edible cactus.

2. What is the flower language of cactus?

Strong, warm, resolute love, strong on the outside but soft on the inside.

What kind of soil does the cactus use to raise it?

Cactus likes to grow in neutral or slightly alkaline environment with loose soil, good drainage and good air permeability, so try to choose slightly alkaline sandy soil for planting. For example, the following types of soil are good choices:

1. Coarse sand: coarse sand has the best air permeability and drainage, and contains magnesium, iron and other trace elements, which can provide magnesium and iron for cactus.

2. Plant ash: plant ash has good air permeability, which is rich in potassium, phosphorus and other elements, and can effectively inhibit the growth of bacteria.

3, coal ash: coal ash is alkaline, and good permeability, good water storage, which contains potassium, can be properly added when planting.

4. Vermiculite: vermiculite is a kind of stone similar to coarse sand, its air permeability is very good, and aseptic, generally hydroponic flowers will use it.

5. Red jade soil: red jade soil is a kind of soil accumulated by volcanic ash. This kind of soil is not only breathable, but also rich in potassium and phosphorus.

6. Volcanic stone: volcanic stone is a kind of stone formed by minerals, volcanic glass and bubbles after volcanic eruption. it has good drainage and air permeability and can effectively sterilize.

In addition to the above several kinds of soil, you can also choose rotten leaf soil, forest soil, loam, red jade soil and other mixed use, not only good permeability, but also adequate nutrition.

Third, how does the cactus turn yellow?

First, too much or too little watering: cactus is drought-resistant, generally watering a small amount of water can grow healthily, if watering too much, it will make the basin soil too wet, resulting in extreme hypoxia and yellowing of the cactus. Of course, it does not mean that there is no need to water, for example, in the dry season, it should be properly watered, if it is not watered, the cactus will turn yellow.

Solution: remove the plant, leave it in a cool place for a day or two, and then transplant it into a flowerpot. At the same time, stop watering and fertilizing to improve the air permeability of the soil. In the dry season, water should be watered every day to make the soil moist.

Second, too much fertilization: cactus fertilizer requirements are not high, generally as long as the growth boom to apply an appropriate amount of mature organic fertilizer, but do not apply too much, so as to avoid yellowing.

Solution: stop fertilizing immediately and pour some water, then pour it out, then water it again, and repeat it a few times to reduce the amount of fertilizer in the soil.

Third, the soil is alkaline or acidic: cactus likes to grow in slightly alkaline or neutral soil, if the soil is too alkaline or acidic, it will make the plant yellow.

Solution: timely watering alum fertilizer to reduce the alkalinity of the soil, or applying alkaline solutions such as calcium, magnesium and phosphorus to reduce the acidity of the soil.

Reason 4, too strong light or excessive shade: cactus likes light but does not tolerate strong light. If it is exposed to the sun or placed in a cool place for a long time, the plant will turn yellow.

Solution: if it is exposed to light for a long time, put it in a cool place; if it is kept in the shade for a long time, move it to a place where there is scattered light.

Reason 5, the occurrence of diseases and insect pests: leaf spot disease will occur during the growth of cactus, resulting in leaf wilting or yellowing.

Solution: remove the disease department and spray topiramate or carbendan for prevention and treatment.

The above is the cactus suitable for the use of soil and yellowing solutions in detail, I hope it will be helpful to you.
