How to fertilize crab claw orchid, what is the best fertilizer to apply crab claw orchid

Generally speaking, we can apply a thin layer of nitrogen fertilizer to promote the growth of the plant during the growth period of crab claw orchid, and we can apply phosphorus fertilizer before flowering.

Crab claw orchid fertilization should generally be carried out during the growth period, and flower lovers need to pay attention to the fact that when there are flower buds and flowering, do not water more, let alone fertilize, otherwise it may lead to bud dropping.

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 fertilizer-tolerant, which is easier to say; If you take cuttings, you have to be careful, no matter whether you are a white crab, a red crab or a pink crab, the root system is very intolerant to fertilizer, and you will burn the roots if you are not careful, so the fertilizer used each time is the amount of 3-5 compound fertilizers, a word "thin".

After the crab claw orchid flowering period, we do not apply fertilizer first, and when the dormant period is over, when new shoots are released, we apply thin nitrogen fertilizer every two weeks.

In autumn and winter, crab claw orchids begin to bud, at this time we can give thin phosphorus fertilizer every 1-2 weeks, and when it is time to flower, fertilizer should be suspended.

Phosphate fertilizer can promote flower bud differentiation, early flowering and fruiting, promote the development of crop roots, and enhance the ability to resist cold and drought. Promote early maturity of crops, increase the number of grains, and improve fruit quality by fullness of grains. When phosphorus is deficient, young shoots and roots grow slowly, the plant is short, and the leaves are dark green, dull, and purple on the back.

Nitrogen fertilizer effect: promote the growth of crop stems and leaves, and the leaf color is dark green.

The role of potassium fertilizer: promote the growth of crops, thick and hard stalks, enhance the resistance to pests and diseases and lodging; Promotes the production of sugars and starches.

Crab claw orchid is generally fertilized before flowering, and fertilization should be stopped when flowering, otherwise it will cause the flower buds to fall and shorten the flowering period. Before flowering, when the buds have just grown or are about to emerge, you can apply fertilizer, mainly fertilizers containing phosphorus and potassium.

1. Bone meal can be used, which is actually rich in phosphorus and potassium, which can meet the flowering needs of crab claw orchid, and bury bone meal along the edge of the pot to provide sufficient nutrients for the plant and promote its rapid flower bud.

2. You can also directly spray potassium dihydrogen phosphate foliar fertilizer on crab claw orchid, which can promote the plant to give birth to more flower buds, more and more colorful flowers, and the flowering period can be relatively longer. About once every half a month, you can apply fertilizer 2-3 times in a row, and stop fertilizing after the buds open to avoid premature flower aging.

3. In addition to applying "flower-promoting fertilizer" to crab claw orchid, during flowering, light and watering should also be paid attention to. Crab claw orchid can be placed in an environment with sufficient astigmatism, and receive more than 6 hours of light every day, which can make the flowering time of the plant longer, and it is also conducive to post-flowering recovery.

Crab claw orchid has a certain drought tolerance, but it is necessary to control watering during the flowering period, and do not water if the soil is not dry. If you water frequently, there will be flower drops. Each watering should be slowly poured along the edge of the pot, being careful not to water on the buds to avoid the bud falling.

Fertilize the crab claw orchid in spring, so that the fertilizer is more reasonable.

Nitrogen fertilizer is best applied to crab claw orchid. Phosphate and potassium fertilizers should also be included, mainly nitrogen.

The use of nitrogen fertilizer can be increased during the growth period of crab claw orchid, and phosphate fertilizer and potassium fertilizer should also be included. Flower fertilizer, which is mainly nitrogen-based, can promote the growth of leaves. When flowering, phosphorus and potassium fertilizers are the main fertilizers, followed by nitrogen fertilizers, which can promote flowering.

In general, compound fertilizers with higher nitrogen content are used during the growing season, and compound fertilizers with higher phosphorus and potassium content can be used during flowering.

Crab claw orchid likes fertilizer, and you can bury some bottom fertilizer when planting. For example, ripe cake fertilizer, farmhouse fertilizer, garbage fertilizer, and long-term base fertilizer purchased and sold are buried at the bottom of the pot, which can provide long-term growth of crab claw orchid, and can be applied some phosphorus and potassium fertilizer during the flowering period to facilitate flowering.

Crab claw orchid needs timely fertilization to lay the foundation for flowering, phosphorus and potassium fertilizer can be applied before flowering, and 1% potassium dihydrogen phosphate can also be sprayed on the leaves to promote flowering. Fertilize during the growth period, and at the time of flower buds and flowering, control the watering and stop fertilization, otherwise bud drop will occur.

Crab claw orchid can be fertilized every 15 days during the growth period, and phosphorus and potassium fertilizer can be applied 1-2 times in autumn. If it is a new grafted branch, do not splash on the grafted healing place when fertilizing, so as not to rot, there is a short dormancy period after flowering, watering should be controlled, fertilizer should be stopped, and then fertilization and watering should be carried out after it grows new shoots.

Crab claw orchid is one of the common flowers in life, and many friends in life are raising crab claw orchid, because it blooms very beautifully and has a high ornamental value. But in the process of maintaining the crab claw orchid, if you want it to bloom more, maintenance skills are indispensable, among which fertilization is very critical, so what fertilizer is good for crab claw orchid? Let's take a look!

1. Nitrogen fertilizer: different fertilizers should be applied to crab claw orchid in different growth stages, mainly nitrogen fertilizer during the growth period, nitrogen fertilizer can promote growth, promote better germination and growth of branches and leaves, or add nitrogen-rich compound fertilizer to crab claw orchid.

2. Phosphorus and potassium fertilizer: Phosphorus and potassium fertilizer should be applied before flowering, such as well-rotted farmhouse fertilizer and cake fertilizer, which are rich in nutrients and can be added to the plant, and phosphorus and potassium fertilizer can play a role in promoting flowering, so that crab claw orchid blooms vigorously and prolongs the flowering time.

The fertilization method of crab claw orchid is as follows:

After each flowering, do not apply fertilizer urgently, and when the dormant period is over, the plant begins to grow again, and some branches begin to germinate, and then start fertilization. Nitrogen fertilizer is applied every two weeks to promote better germination and vigorous growth of branches and leaves. Wait for the autumn and winter plants to sprout buds, at this time to replace the fertilizer, choose phosphorus and potassium fertilizer, every one or two mills once a week, and wait for the flowers to start opening when the fertilizer to avoid falling flowers.

Fertilization is to directly bury the soil to apply granular fertilizer, can also apply diluted fertilizer, thin fertilizer diligent application it can be well absorbed.

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.
