Maintenance of white orchid during flowering period

I. Sufficient light

White orchids like to grow in an environment with sufficient light, and the light should not be less than 6 hours a day. White orchids, if kept in shade, will have only leaves and no flowers, or very few flowers. However, in the hot and high temperature "dog days" and moderate shade, generally 12-16 hours a day to avoid the sun exposure. At this time, not only to spray water to cool the plants, but also to water or spray water to cool the ground, artificially create a suitable environment.

2. Proper watering

White orchid watering must pay attention to, excessive or insufficient watering will lead to white orchid root growth limited or even rotten roots, and then leaves will appear yellow problem. Summer high temperature should always pay attention to whether the pot soil is wet, in addition to watering in the morning and evening, there are water spraying on the leaves and ground to improve the air humidity. If tap water is used to irrigate white orchids, attention should also be paid to preventing soil alkalization. If leaves are found to be yellow, ferrous sulfate water should be applied, or a mouth of 0.7%-0. 8% acid vinegar water doused roots. 0.3%-0.4% acid vinegar can also be used to spray leaves, the effect is also very good. In the rainy season in spring flower pots can not be water, otherwise it will rot roots.

3. Reasonable fertilization

White orchids are more fertile, so they should be fertilized regularly to supplement nutrients in time, so as to make them bloom more, flowers bigger and flowers fragrant. In addition to applying sufficient base fertilizer when putting on the pot, organic liquid fertilizer based on phosphorus and potassium, such as decomposed cake fertilizer water, should be applied every 5~7 days from May to October during flowering. The principle of fertilization is to apply thin fertilizer frequently. At the same time, fertilization outside roots was carried out once every 7~10 days, with 0. 5% plant growth promoter and 0.3% potassium dihydrogen phosphate were sprayed on leaves.

IV. Leaf picking and topping

White orchid out of the room time between the vernal equinox to Qingming, choose cloudy or cloudy weather out of the room, in the room after 2, 3 days to let potted flowers adapt to the outdoor environment, and then began to remove the old leaves of the plant, leaving only a few tender leaves at the top of the branch, let it promote new shoots. Then, after each batch of flowers, remove a small number of old leaves to promote new branch growth and flower bud formation. During the growth period of white orchids, it is necessary to frequently pick the core to control the apical dominance and promote multiple branches.

When does the white orchids bloom? What is the maintenance method of white orchids flowering?

White orchids are famous garden ornamental trees, mostly planted as street trees, cultivated in Fujian, Guangdong, Guangxi, Yunnan and other provinces in China, so when does white orchids bloom? What is the maintenance method of white orchid florescence?

When do white flowers bloom?

White orchids bloom in summer and autumn every year. The farther south they go, the earlier they bloom. Shenzhen has about midsummer. The flowering period is relatively long and can last almost one month. The flowering period of white orchid is April to September, the flowering period of vermilion magnolia is April to May, the flowering period of purple orchid is April to July, and the flowering period of magnolia is June.

How to make white flowers bloom:

1. Leaf picking: remove the leaves once before and after leaving the room, remove all the old leaves, and leave only a few leaves on the branches to promote new branches and leaves and promote bud breeding. During the growth period, three times of topping are required: the first time is taken after the flower withers to promote new buds and more buds; after that, two times of topping are required at intervals to make the flowers flourish and beautiful, and the flowers bloom continuously.

2. Timely fertilization: in the blooming period from early May to the end of September, the principle of thin fertilizer and frequent application shall be adopted to strengthen fertilizer and water management. Apply decomposed soybean cake fertilizer solution once every 3~5 days, and apply phosphate fertilizer water once every 7~10 days to wake up alternately. It is necessary to add 1~2 times of available phosphorus and potassium fertilizer before flowering, which can make white orchids bloom continuously.

3, reasonable watering: pot soil should not be too wet, spring watering should not be more, keep pot soil moist is appropriate. Summer growing season prevents dryness to prevent leaves from drying out. Autumn watering should be slightly more than spring, each watering should be watered thoroughly. The frequency of watering should be gradually reduced at the end of autumn. Rainy season needs to drain water, in case of rotten roots, yellow leaves.

White orchid flowering maintenance methods:

1. Light should be soft: white orchids like light. In summer, they can be placed under a shaded flower shed. In the morning, open the curtain to let them receive sunlight. After 9 o 'clock, cover them to avoid sunlight, especially avoid direct sunlight at noon.

2. Water should be frequent: white orchids like to be wet. They should be watered frequently in summer. It is best to irrigate once every morning and evening. In the morning and afternoon of high temperature, water should be sprayed twice on the leaves and surrounding areas to increase humidity. Because their roots are fleshy roots, they are afraid of ponding. In rainy days, they should be watered less or not watered. In case of rain, timely attention should be paid to the drainage in the basin to prevent the roots from rotting due to soaking, resulting in the death of the whole plant. Because white orchids are typical acidic flowers, afraid of alkali, the water in the north is alkaline, and long-term use is easy to cause leaves to yellow and fall off, so it is best to use the rainwater stored at intervals when watering, and it can also be irrigated with ferrous sulfate.

3, fertilizer should be large: white orchids in the growth period like large fertilizer water, not only to irrigate good water, but also should apply good fertilizer. Fertilization is best with liquid fertilizer, horseshoe slices, sesame paste, ferrous sulfate, according to the ratio of 1:1: 0.5 after mixing water soak for a week, fermentation, diluted with water every 5 days after application of a better effect, flowers and leaves wide hypertrophy, flowers fragrance.

4, anti-insect: white orchids in the summer is most vulnerable to red spider damage, usually to the leaves and plants to increase humidity, to prevent pest occurrence, such as the occurrence of a small number, can be sprayed with water to wash the leaves, such as a large number of insects, can spray 1000 times of 20% dicofol EC pest.

Maintenance of white orchid in full bloom July, August, September, is the growth season of white orchid, but also its full bloom, during this period if improper maintenance, will cause leaves to wither, or even the whole plant death, maintenance well, will flourish, flowers constantly.

1. Light must be soft. White orchids like light, summer can be placed under a shady flower shed, open the curtain in the morning, let it receive sunlight, after 9 o 'clock should cover, shelter from sunlight, especially to avoid direct sunlight at noon.

2. Water should be frequent. White orchids like wet, summer should be watered frequently, it is best to irrigate once every morning and evening, spray water twice in the leaves and surrounding areas in the morning and afternoon of high temperature to increase humidity, because their roots are fleshy roots, afraid of ponding, in rainy days should also be watered less or not watered.

3. Fat must be big. White orchids in the growth period like big fat water, not only to irrigate good water, but also should apply good fertilizer. Fertilization is best with liquid fertilizer, horseshoe slices, sesame paste, ferrous sulfate, according to the ratio of 1:1: 0.5 after mixing water soak for a week, fermentation, diluted with water every 5 days after application of a better effect, flowers and leaves wide hypertrophy, flowers fragrance.

4. Good bug proofing. White orchids are most vulnerable to red spiders in summer. At ordinary times, more water should be sprayed on leaves and plants to increase humidity to prevent insect pests. If there is a small number of insects, spray water to wash leaves. If there are more insects, spray 1000 times of 20% dicofol emulsifiable concentrate.
