Under what circumstances will the cactus bloom (why does the cactus bloom)

Some netizens asked : Why do cacti bloom? Under what conditions do they bloom?

Cactus usually blooms in the early morning or evening and lasts for a few hours to a day.

The cactus blooms like other plants to reproduce the next generation and bear fruit. The purpose of flowering is to spread the pollen of the plant. The bright colors and many of them have fragrance can attract insects to spread pollen, thereby completing the purpose of fertilization.

Under what conditions does the cactus bloom?

There are many varieties of cacti, and some common plants do not need too long to grow, usually 2 to 3 years. However, some rare varieties can take more than 10 years to bloom.

Generally, cacti will bloom and bear fruit after 2 to 3 years of growth. If they grow in good health, have a suitable growing environment, sufficient light, and a certain amount of "phosphorus and potassium supplements", they will bloom and bear fruit.

How to maintain cactus to achieve more flowering

First, the soil for planting flowers

The soil for cactus is generally neutral in pH value, and it should be loose and breathable, and fine soil without compaction or water accumulation. Suitable soil allows cactus to grow healthier and is also the basis for flowering.

When using flower soil, it is recommended that you use honeycomb coal powder + volcanic rock + humus soil, take 1/3 of each and mix them, and then add about 10% of perlite. A small amount of eggshell can be added to the mixed soil.

Second, the maintenance environment

In the first one to two years of planting cacti, they are generally kept in a semi-shaded environment, with about 3 to 5 hours of sunlight in the morning or evening every day. This maintenance method can make the bulbs grow quickly.

However, when growing in a semi-shaded environment, be sure to rotate the flowerpot every month to allow the spherical fleshy stem to receive light evenly.

After about 2 years of maintenance, you can let the cactus grow in full sunlight. Move the cactus to a location with open space, good ventilation and more than 8 hours of sunlight.

Even in the summer, there is no need for shade, unless the summer temperature reaches 40 degrees Celsius. Under long-term light, the photosynthesis of cactus is better and it is easy to bloom.

Third, watering method

The method of watering cactus is very simple. In spring, you can water it once a month. In summer and autumn, water it about once a week after the surface of the flower soil is dry and white.

In winter, you can water it once a month and spray the fleshy stems 2 to 3 times a week. You can water it in this way in the first one to two years of maintenance.

After 2 years of maintenance, if you want the cactus to bloom more, you can limit the water in early summer, because it is already an old pot. Water it in time and wait until the fleshy stem of the cactus has a slight wrinkle phenomenon before watering.

However, it is recommended that you spray the fleshy stems once a week during the dry period of the flower soil. Appropriate water restriction can inhibit the root system's absorption of nitrogen and promote flowering.

Fourth, fertilization method

Fertilization is essential for the maintenance of cacti, and the method of using fertilizer should also be different. In the first two years of planting, the organic fertilizer used can be "bean cake fertilizer water" with a high nitrogen content. The supplement of nitrogen can significantly speed up the growth of fleshy stems.

When applying fertilizer, as long as the temperature is not lower than 10 degrees Celsius and not higher than 35 degrees Celsius, organic fertilizer can be applied once a month.

After the cactus has grown for two years, the method of fertilizing can be changed, and the organic fertilizer can be replaced with organic fertilizer with balanced nutrients.

Apply the fermented sheep dung balls and bury them shallowly in the topsoil by loosening the soil. Sheep dung balls have a mild and long-lasting fertilizer effect. The "nitrogen, phosphorus and potassium" they contain are more easily absorbed.

During the flowering period of cactus, apply 1500 times of "potassium dihydrogen phosphate" to the fleshy stems. Potassium dihydrogen phosphate can promote the flowering of cactus and prolong the flowering period .
