How to fertilize crab claw orchid? When is it good to fertilize crab claw orchid?

In the early stage of growth, that is, before flowering, crab claw orchid basically grows stems and leaves, which is the time to grow and expand the structure, and the consumption of nutrients is basically based on nitrogen fertilizer, so if you fertilize at this time, you can consider some nitrogen-biased fertilizers, such as urea. For the later stage of growth, that is, after flowering, at this time, the crab claw orchid will be transferred from vegetative growth to reproductive growth, so the demand for fertilizer for the crab claw orchid at this time is mainly phosphorus and potassium fertilizer, light nitrogen fertilizer, so when fertilizing, you can consider high phosphorus and potassium fertilizers such as potassium dihydrogen phosphate, of course, you can also choose to apply some high phosphorus and potassium flower compound fertilizers.

Crab claw orchid is generally fertilized once every 15 days, eat thin nitrogen fertilizer every two weeks, and crab claw orchid is best fertilized before watering.

First, the fertilization of crab claw orchid generally only needs to put fertilizer on its roots. And fertilizing every 15 days will do. Second, crab claw orchid only needs to use ordinary compound fertilizer.

First of all, use the most common fertilizer, usually water more, bask in more sunlight, prune more branches and leaves, water once every 10 days, 100 ml once, and fertilize best when the weather is warm.

Thin nitrogen fertilizer is applied to promote plant growth, and phosphorus fertilizer is applied before flowering, and fertilization is carried out during the growing season.

We should use scientific methods to fertilize. Generally, it is best to apply fertilizer not too much in summer, and apply it once every month to a month and a half.

Also known as cactus and Christmas cactus, Crab Claw Orchid belongs to the cactus family. Many friends like to maintain crab claw orchids, but they don't know that they will not be able to use chemical fertilizers until they bloom next year. If the nutrients are insufficient, it can easily affect the appearance of the plant.

Crab claw orchid is beautifully fertilized, and when fertilizing, the amount of fertilizer applied is very important. If these details are not handled properly, it can backfire.

1. Fertilization period: As soon as March arrives, the rose-red flowers will bloom on the branches of the crab claw orchid. Flowering is only in March.

When the flower dies at the end of the month, it will enter a period of time. In a dormant state, fertilization should not be applied at this time. When the plant returns to its growth state, new shoots will grow on the stem nodes.

This status means that top dressing can begin. When the crab claw orchid returns to its growth state, nitrogen fertilizer should be supplemented as much as possible, which can make the branches of the plant grow rapidly and make the color emerald green. Nitrogen fertilizer is a soil fertilizer, so be careful when applying it.

Sprinkle on branches and leaves so as not to burn the plant.

2. Potted fertilizer: No matter what kind of flowers or green plants are maintained for a period of time, the pots need to be replaced, and crab claw orchid is no exception. Under normal circumstances, crab claw orchids that have been growing for two years will have to change the potting soil once.

When replacing the soil, you can apply fertilizer by the way. First, put some coarse grit on the bottom of the pot. The gap between the coarse sand is good for drainage.

Adding a small amount of decomposing fertilizer and agricultural fertilizer on top of it can greatly improve the fertility of the potting soil. Agricultural fertilizers have better fertilizer and water retention capacity to ensure that the plants have enough nutrients for the plants to grow later. The base fertilizer mixed in the potting soil should be fused with the potting soil to avoid excessive fertilizer concentration.

Plants that go into pots do not absorb nutrients evenly. Concentrated fertilizer is likely to cause local thickening of crab claw roots, resulting in the appearance of blue claws. Heavy yellow leaves appear.

3. Grafting and fertilization: When grafting, the fertilization time must be mastered to facilitate the growth of plants. Don't be in a hurry to fertilize the crab claw orchid after grafting, first put the plant in a cool place.

The upper curing period is usually half a month. During this time, do not expose yourself to the sun for long periods of time and do not rush to fertilize. You just need to keep the potting soil moist.

After this time, the crab claw orchid is basically grown and mature, and can be placed in the sun to grow. Since the incision of the graft dries out, it is necessary to water and moisturize after fertilization. Fertilization after grafting is mainly liquid fertilizer.

4. Fourth, normal fertilization management: In the daily growth of crab claw orchid, the general topdressing interval is half a month. Each top dressing should be changed according to the growth stage of the plant.

Nitrogen fertilizer should be applied as much as possible during the vigorous growth period to ensure the color and growth trend of the branches and leaves. It is best to apply potassium fertilizer to crab claw orchid during the flowering period, potassium can promote the flowering of flowers and increase the number of flowers. Friends who care for crab claw orchids, when the plant is in a pot, you should prepare.

Crab claw orchid is generally fertilized in the growth period is better, fertilized once every half month, in autumn need to increase phosphorus and potassium fertilizer, 1 to 2 times is better, in the crab claw orchid bud and flowering should be stopped fertilization, so as not to lead to bud drop.

When the buds have grown, this is the most suitable time to fertilize, so that the color will be very bright after flowering.

1. After the stem node grows new shoots, apply thin nitrogen fertilizer once every half a month, do not water the leaves, which will affect the growth of the stem;

2. Fertilize the pot, pad a layer of 3 cm of coarse sand particles at the bottom of the pot to facilitate drainage, add less decaying animal manure or bone meal fish scales to the soil, increase the fertility of the soil, and the root system of the New Year's Day is not in direct contact with the fertilizer. Crab claw orchid is repotted every two years, in March and April;

3. Do not fertilize immediately after grafting, put the plant in a cool place, after a week, after the grafting incision is dry, first fertilize and then water, mainly liquid fertilizer;

4. It can be applied once every half a month normally, and potassium fertilizer and phosphate fertilizer can be increased in the flowering and growing season.

For crab claw orchids that have flower buds, thin fertilizer should be applied every 10 days, such as potassium dihydrogen phosphate, the concentration is about and about, and multiple compound fertilizers can also be used; Under normal circumstances, for the crab claw orchid that has appeared Hongqing flower buds, the room temperature should be maintained above 10 degrees Celsius in winter, and there should be a slight light, and the potting soil should be dry, not too much watering or often too wet.

In order to make the flowering of crab claw orchid flourish and bright, after the dormant period of midsummer, fertilizer should be added in time, and the soil can be used with 1:1:1 compound fertilizer. The foliar surface can be sprayed with a solution of potassium dihydrogen phosphate.

From spring to summer, thin liquid fertilizer can be applied once every 10 to 14 days, and fertilizer can be stopped during the high temperature period in summer; From the beginning of autumn to flowering, fertilizer and water should be continuous, generally apply liquid fertilizer or compound fertilizer once a week, and add 1 to 2 times of fast-acting phosphate fertilizer before flowering. During this period, sufficient nutrients should be supplied, which is conducive to the formation of flower buds and bright flower colors.

Crab claw orchids need to be repotted every two years, usually in March to April. When changing pots, the main attention is to fertilization, first on the bottom of the pot Qijue mountain pad a layer of 3 cm of coarse sand particles, easy to drainage, and then add a small amount of high and medium decaying animal manure or bone meal fish scales to the soil to increase the fertility of the soil.

Crab claw orchid flowering can not be fertilized.

Crab claw orchid should not be fertilized when it is in bloom, as fertilization at this time will easily cause the flower buds to fall and shorten the flowering period.

It is best to choose before flowering, that is, when the flower buds have just grown or are about to sprout buds, apply phosphorus and potassium fertilizers, bury bone meal along the edge of the pot, and spray potassium dihydrogen phosphate foliar fertilizer, which can promote it to grow more flower buds, and the flower color will be more vivid and longer when it blooms during the Hanxin Zen period. Usually top dressing once every ten days and a half months, and the fertilizer can be stopped after the buds open to avoid falling flowers.

More sun: the flowering period of crab claw orchid is mainly concentrated in winter and spring, although it has a certain shade tolerance, but the light at this time is very soft, in order to promote its better flowering, it is best to bask in the sun, move it to the environment of astigmatism, receive more than 6 hours of light every day, which can promote the flowering period to prolong, but also conducive to the recovery after flowering.

Strict water control: crab claw orchid has a certain drought tolerance, watering during the flowering period should be controlled, it is best to use dry and wet watering, do not water if the soil is not dry, dry and wet alternately can promote better flowering. If you water too often, it will easily lead to flower fall.

In addition, you should also pay attention to the method when watering, it is best to talk about dust along the edge of the pot to slowly penetrate the water, and do not let the flower buds get wet to avoid falling flowers.

Moderate temperatures: Although crab claw orchid blooms in winter and spring, it is extremely cold-tolerant. If you want it to bloom better, you must have a good temperature control and warmth during the flowering period.

It is best to control the temperature between 15-20, and the minimum temperature should not be lower than 10, otherwise it will affect flowering. In addition, if there is heating indoors, stay away from the heating equipment to avoid the crab claw orchid being roasted.

1. Stop fertilizing during the dormant period.

2. After the crab claw orchid blooms in March, it will enter a dormant period, which will not be long, depending on the specific growth ring spring hail situation. Fertilization is stopped during the dormant period until new shoots grow on the stem nodes and normal water and fertilizer management is resumed. Apply thin nitrogen fertilizer once every half a month, and do not water the leaves when fertilizing, so as not to affect the growth of the stem.

4. Change pots and fertilize.

5. Crab claw orchid needs to be repotted every two years, generally in March and April. When changing pots, the main attention is to fertilization, first on the bottom of the pot pad a layer of 3 cm of coarse sand particles, easy to drainage, and then add a small amount of decaying animal manure or bone meal fish scales to the soil to increase the fertility of the soil. Pay attention to the root system should not be in direct contact with the fertilizer, so as not to cause fertilizer damage and affect the growth.

6. Grafting and fertilization.

7. Grafting is conducive to the growth of plants. Do not fertilize immediately after grafting, first put the plant in a cool place, and after a week, after the grafting incision is dry, fertilize first and then water, and fertilize mainly with liquid fertilizer.

8. Normal maintenance.

9. Normal maintenance is loved, fertilization can be applied once every half a month, and potassium fertilizer and phosphate fertilizer can be appropriately increased in the flowering and growing season.

Apply bottom fertilizer when changing pots in spring, wo horseshoe.

Crab claw orchid fertilization bai is generally required.

DU should be carried out during the growth period, when there are zhi flower buds and flowering dao, do not water more, and do not fertilize again, otherwise it may lead to the fall of buds.

In addition, for the fertilization of crab claw orchid, it is necessary to distinguish whether it is grafted, and a small amount of compound fertilizer or liquid fertilizer is used for grafting, and most of the rootstocks are more resistant to fertilizer, and the amount of compound fertilizer is 3-5 grains, a word "thin".

In the growth period of crab claw orchid, it can be fertilized once every half month, and 1 or 2 times of phosphorus and potassium fertilizer in autumn, grafted new branches, when watering and fertilizing, pay attention not to splash the grafted healing place, so as not to rot, and there is a generally short dormant state after flowering, watering should be controlled, fertilizer should be stopped, and normal fertilizer and water management should be carried out after the stem node grows new shoots.

Just sprinkle some compound fertilizer or something once in a while, mine is like that, waiting for the experts in this area.
