What kind of fertilizer should be applied to cactus? Do cacti need to be fertilized? What fertilizer

To maintain the cactus, what fertilizer to apply to make it continue to bloom, you will know which one to use after reading it.

Cactus fertilizes with "it", which grows fast and round.

Cacti and cacti generally do not require much fertilizer. Under normal circumstances, a multi-element slow-release fertilizer can be applied once during the growth period. Moreover, the growth period for newcomers is generally in spring and autumn, when the temperature is cooler.

Therefore, the fertilizer efficiency of general slow-release fertilizer lasts for three months, so it is enough to apply slow-release fertilizer once each time in spring and autumn.

Use some rotted manure and add it at the time of repotting. I don't usually apply much fertilizer, and if the concentration is large, I will burn it to death.

There is that kind of cactus special fertilizer, you can try it.

I don't think I need to, because I don't think it's watered very much.

Check this out to you.

Cacti are best used with nitrogen-based fertilizers and fertilizers with high phosphorus and potassium content.

Cactus fertilization is divided into two stages, one is the growth stage, the other is the flowering stage, the growth stage of fertilization is supplemented with nitrogen-based fertilizer, which promotes its rapid growth of the ball, and quickly grows the ball and grows full. Cactus balls can be sown from seeds, and the seeds will gradually grow after sowing, and they can only bloom after they grow to a certain size.

Therefore, in the season when it grows, when it does not bloom, we only need to add fertilizer with high nitrogen content to it, nitrogen fertilizer can promote it to grow a sphere, and the root system grows better, the content of nitrogen is high, and other elements are also contained, which can ensure that it gets more nitrogen fertilizer, and the sphere grows fast and full.

Another is to fertilize it during the flowering period, if the cactus is a variety that blooms more frequently, such as scarlet jade Luan Fengyu and the like, they will continue to grow and bloom in the spring as long as the temperature is higher than 20 degrees, and continue to bloom, in its flowering season, as far as possible to choose fertilizers with high phosphorus and potassium content to supplement it, phosphorus and potassium elements can effectively promote its flowering, so that it comes out of the buds more, flowering will bloom more.

Don't give it potassium dihydrogen phosphate alone, potassium dihydrogen phosphate, its phosphorus and potassium content is quite high, and other elements are basically not, which will cause it to bloom more, and the sphere will be shriveled and yellow.

<> compound fertilizer: according to the size of the pot, about 5-15 grains per pot are applied, and the fertilizer effect is better.

Phosphorus and potassium fertilizer: Cactus balls should be applied more phosphorus and potassium fertilizer, which can make the plant grow well and the ball body full and strong.

Animal manure: Sheep manure, cow manure, chicken manure, human manure and other decomposed manure are used as base fertilizer, which not only continuously releases fertilizer efficiency, but also is relatively mild.

Grass ash: Cactus likes potassium, and plant ash contains more potassium.

Bone meal and horns: Cacti like phosphorus, and bone meal and horns contain more phosphorus.

1. Compound fertilizer

The nutrients contained in the compound fertilizer are relatively comprehensive, and the effect speed is also very fast, and it can be directly dissolved in water when used, and the effect on the cactus is better. For grafted balls, more nitrogen, phosphorus, and potassium compound fertilizers should be applied. When using granular fertilizer pot surface spreading, it must not be excessive, according to the size of the pot, it should generally be controlled between 5-15 grains.

2. Phosphorus and potassium fertilizers

Cactus fertilization is mainly based on phosphorus and potassium fertilizer, and the use of nitrogen fertilizer can make the cactus grow well and the sphere is full and strong. Phosphate fertilizer can effectively promote the development of cactus bulb root system, promote the development of seeds and fruits. Potassium fertilizer can participate in the activity of a variety of enzymes in the sphere, promote the synthesis of plant protein, fat and starch, and can also improve disease resistance and reduce unnecessary water loss.

3. Animal manure

Apply sheep dung, cow dung, chicken dung, human manure and other manure to the cactus, pay attention to the decomposition before applying, it is best to use it as a base fertilizer. Manure is a common organic fertilizer in raising flowers, belongs to natural fertilizer, there is no harm to the plant and there is no pollution, although there is a slight unpleasant smell, but after complete fermentation, it is incomparable to many fertilizers, not only sustainable release of fertilizer effect, but also relatively mild.

Fourth, plant ash

When fertilizing the cactus, you can choose plant ash, because the plant ash contains more potassium, and the cactus likes potassium fertilizer, which can be mixed in the soil and is conducive to growth.

5. Bone meal and horns

Bone meal and hoof horns contain more phosphorus, and the effect time is long, but before application, it should be soaked, the hooves should be sliced first, and then soaked in water, and the above clear liquid should be taken after soaking, and it can be directly watered.

Cactus balls need to be fertilized in time during the growing season, otherwise flowering will be affected. When fertilizing cactus, attention should be paid to the following issues: book travel.

1. Cactus fertilization should be done once every 15-20 days, and it should be mastered when fertilizing"It is better to be light than thick, and thin fertilizer is applied diligently"principles;

2. Generally, the fertilizer of cactus is mostly rich in potassium, phosphorus and less nitrogen fertilizer, which can be diluted and used;

3. Calcium can make the thorns of the Xiannian human ball grow bright and strong;

4. Grass ash is not only an excellent potassium fertilizer, but also rich in alkaline, mixed into the culture soil, which can adjust the acidity and alkalinity of the soil and improve the acidic soil.
