How to maintain large leaved orchids, breeding methods and precautions for large leaved orchids

1. Venue.

The place where the orchid is placed is very important, and it directly affects the growth and development of the orchid. Orchids are generally placed in the open field in spring, summer, and autumn (in the shade of the open field in summer) and indoors in winter. It is best to be outside in an open area with humid air.

There should be plenty of light indoors, preferably facing south. In this way, it is beneficial for orchids to grow. It is best to place the orchid basin on a wooden frame or table, not on the ground.

2. Shade.

Orchids are mostly semi-negative plants, and most species are afraid of direct sunlight and need proper shade. Orchids can be exposed to more sunlight in early to mid-April to promote their growth. Proper shade should be provided after late April.

The varieties with erect leaves in the summer orchid and autumn orchid should be placed in the south of the shade place, so that they can be exposed to more sunlight. Weeping autumn and spring orchids are better exposed to two hours of light every day. From June to September, shade should be provided early every day, such as reed curtains can be used dense curtains or two layers of thin curtains. After October, the weather becomes cooler and the sun is weaker, so you can postpone the shading, but you still need to pay attention to the shading work around noon.

3. Rainproof.

Orchids can be showered with light rain, but avoid mildew rain, showers, or continuous rain. In the mildew rainy season, it is especially necessary to do a good job of rain prevention. From late June to mid-September, showers are common.

If the rain is short and the rainfall is small, you should water more in the evening to let the heat in the pot be discharged, otherwise the orchid will be damaged, and even the roots will rot and die. If the sun comes out again after a shower, shade should be taken in time to prevent the rise of heat on the ground and affect the growth of orchids.

In the rainy season, it is the stage when orchids extract leaf buds, and if the potting soil is too warm, the leaf buds will not grow well or cause diseases. At this time, a small amount of plant ash can be sprinkled to adjust the moisture of the potting soil.

4. Watering.

The flower proverb says:"Dry orchid wet chrysanthemum"There is some truth to this. Generally speaking, orchids are best in eight parts dry and two parts wet.

If it is too wet, it is easy to cause the flowers to rot and die. The principle of watering should be: dry watering, wet stopping, appropriate drying.

Specifically, it should be noted that more watering should be done during the growing period (May to the end of June), less watering should be done at the budding stage (about March to April) and flowering period (about March to April), and less watering should be done during the dormant period (winter). Pots with large pots and small orchid plants should be watered less, and potted plants with large plants should be watered more.

When the climate is hot and dry, it should be watered more appropriately, and when it is cold and humid (such as mildew rainy season, etc.), it should be watered less or no watering. If the orchid is newly dug from the mountain, if the root system is sparse or there are many broken roots, it should be watered less to make the potting soil dry a little, so that the roots will not rot, which is conducive to extracting new leaves.

Hello! Orchid cultivation method:

1. Apply thin fertilizer frequently.

Orchids like fertilizer, but not tolerant of thick fertilizer, when breeding potted orchids, need to be fertilized in accordance with the principle of thin fertilizer diligently, fertilizer can be applied every 3-4 weeks, you can choose diluted liquid fertilizer, or phosphorus and potassium thin fertilizer, to provide orchids with the nutrients needed for flowering, so that the flowers of the plant are more brilliant.

2. Control watering.

Orchids should avoid waterlogging, when breeding potted orchids, if watering too often, it will lead to rot of the root system of the plant, so that the orchid wilts and dies, and needs to be watered after the soil is completely dry, and during the rainy season, the potted orchid should be moved to a dry place indoors for maintenance.

3. Lighting conditions.

Orchids are not tolerant to strong light, but if they are placed in the shade for a long time, it will cause the plant to be difficult to flower, when cultivating potted orchids, you need to do shade measures for the plants in spring and summer, and in autumn and winter, you can place potted orchids in a sunny place to promote their healthy growth.

4. Maintenance method.

When maintaining potted orchids, it is necessary to place the plants in a ventilated environment to avoid poor growth of orchids, and to rotate the pots of orchids every half a month to make them receive light evenly, and to change the potting soil for orchids every 2-3 years, you can use sandy loam soil with good drainage.

1. Breeding environment: Large-leaved orchids should be cultivated in early spring, late autumn and winter to provide full sunshine and scattered light in summer. 2. Water and fertilizer management

Large-leaved orchids are afraid of waterlogging, so they can be watered thoroughly when watering, and fertilization can only be applied after new roots grow. 3. Precautions: During the breeding period, it is necessary to constantly prune dead branches and dense branches, and disinfect the plants.

1. Breeding environment

Large-leaved orchid is a shade-loving plant, before April every year, to provide it with full sunshine, to promote the growth of leaves, after April, to block direct sunlight for large-leaved orchids, to avoid leaves yellow and dry, after October every year, and then provide all-weather natural light.

2. Water and fertilizer management

Large-leaved orchids are not tolerant to waterlogging, potted cultivation can be watered along the edge of the pot, keep the potting soil slightly wet, and water the roots when planting, until the soil color becomes dark, and large-leaved orchids are sensitive to fertilizer, and can only be fertilized after growing new roots, so as to avoid fertilizer damage and death of plants.

3. Precautions

In the process of breeding large-leaved orchids, it is necessary to continue to prune, otherwise the branches and leaves are too luxuriant, too many dead leaves, it will affect the ventilation, consume nutrients in vain, and prune to disinfect the scissors and the surrounding environment to avoid the plant infected with bacteria, and take measures to cover the rain after pruning to avoid wound rot.

1. The base of cultivation is mixed with 5 parts of humus and 1 part of sand and mud or 4 parts of humus, 2 parts of peat, 2 parts of slag and 2 parts of river sand.

2. Seedling division and disinfection: When dividing the pot, first grasp the base of the orchid seedling with the five fingers of the left hand, turn the pot upside down, and gently tap the surrounding of the pot to separate the pot from the pot soil, and then gently pat the soil to shake off the soil. Carefully clean the roots and cut off rotten roots, broken roots, dead leaves and dry false bulbs.

3. Potting: After selecting the pot, before planting, cover the drainage hole at the bottom of the pot with a large piece of broken tiles, and spread it with a window screen, and then spread the coarse grains of mountain mud, you can put it into the orchid plant, the distribution of the orchid plant root sock system should be uniform and stretched, do not touch the pot wall, take out the soil after the soil is wet, rinse the foliar soil with a watering can, place the seedlings in the shade, and transfer to normal management after a week.

4. Management: The cultivation site is required to be well ventilated and has shading facilities. The water requirements of large-leaved orchids mainly depend on the temperature, light intensity and plant growth.

It is better to use rain or snow water for large-leaved orchids, and watering cans are best for watering, which is best before and after sunrise, which is conducive to the growth of large-leaved orchids.

Breeding environment: Large-leaved orchids are suitable for growing in loose and breathable soil, and when maintaining, they need to be placed in a ventilated and sunny place. Water and Fertilizer Management:

During the growing season, water permeable once every 2-3 days, and apply thin liquid fertilizer 1-2 times a month. Repot in time: Change the potting soil every 1-2 years to provide plenty of space for the plants to grow.

1. Breeding environment

Orchid is suitable for growing in loose and breathable soil, so during the maintenance period, you can mix garden soil, sandy soil, and humus soil to prepare soil, and place the plant in a place with sufficient scattered light and ventilation, while keeping the ambient temperature between 15-20 degrees to avoid frost damage.

2. Water and fertilizer management

When maintaining the large-leaved orchid, it should be watered once every 2-3 days during the growth period, keep the potting soil moist, and avoid stagnant water, otherwise the root system will rot and affect the later flowering, and apply thin liquid fertilizer 1-2 times a month to maintain the growth of the plant.

3. Change the pot in time

When potting large-leaved orchids, pots will limit the growth of the root system, you can change the potting soil every 1-2 years to provide sufficient growth space for the plants, and in the process of changing pots, you should prune the rotten roots and rotten roots of the large-leaved orchid, disinfect the wounds, and replant them into the soil.

1. Temperature: It is suitable for growing at a temperature of 10 degrees to 30 degrees, the temperature is higher during the day, and the temperature difference is higher at night, and the temperature difference above 8 degrees is more conducive to growth. In winter, it is necessary to pay attention to temperature control and move to indoor maintenance as soon as possible.

2. Light: Compared with other orchids, it prefers sunlight, so it should usually be placed in the light, and the flowers will be bigger and more beautiful if they bask in the sun.

3. Watering: Big-leaved orchid likes a humid environment, so it should be watered frequently to keep it moist, but pay attention not to accumulate water. During the growing season, 85% humidity should be ensured, and the amount of water should be reduced during dormancy, and 50% humidity should be sufficient.

4. Fertilization: Potassium fertilizer should be applied more at the seedling stage, and organic fertilizer should be applied mainly when the seedlings grow. In addition, it should be combined with foliar fertilizer at the same time.

Its disease is mainly anthrax, which is extremely harmful. When found, mancozeb should be sprayed in time for prevention and control. The insect pests are mainly red spiders and scale insects, and red spiders can be used to earth king and mites. You can use all spirits and quick cullings.
