How to raise orchids on the balcony

It is very important to choose a suitable balcony so that blue seedlings can fully and properly absorb sunlight and accelerate photosynthesis. Although orchids can't stand strong sunshine, everything depends on the sun, and warm and soft sunshine is also essential for orchids.

Seedling selection

This is the key to quickly cultivate excellent seedlings. The basic principle of seedling selection, the first is to choose healthy and delicate seedlings without pests and diseases as much as possible. Once the seedlings with pests and diseases are brought back for planting, if they are not cured in time, the possibility of seedling death is very small. If the disease spreads to other orchids, chickens will lose their eggs and wives will lose her soldiers. Second, try not to choose old and weak seedlings. Weak seedlings not only grow slowly, but also have a very low seedling rate. It usually takes more than one or two years to rejuvenate, and the income is low. Third, try not to pay for seedlings. Two to five seedlings are suitable, which is not only easy to plant, but also has a high seedling rate.

Potted soil

Potted soil is the material basis for cultivating strong seedlings, and scientific selection and reasonable collocation of materials are conducive to the vigorous growth of strains. Generally speaking, oak leaves, Tang Jilan stone, red fairy 10, water bitterness is enough. These materials are easily available in the professional market. Tangjilan stone and hongxianshi are suitable for medium particles. When used, oak leaves, bergelant and red fiber stone are usually matched with one third each. The three are stirred evenly and moistened with water, which is a good pot soil. When planting orchids, they should be classified into coarse, medium and small, so it is not necessary to pay attention to the use of middle and upper, as long as they are filled evenly, because any orchid pot has enough air holes and the soil has enough air-permeable materials.

water

As the saying goes, "it takes ten years to plant orchids and three years to repair them." Watering and moisturizing is a long-term daily work, and it is also the key work to cultivate tender buds and rough Miao Zhuang. The balcony is well ventilated, full of light and easy to dry. There is no fixed watering time and amount. Only according to the environment, temperature and humidity. The general principle is to ensure that the basin soil is moist. As the saying goes, "the root of all evil is water." Long-term excessive humidity in the basin is easy to cause soft rot, stem rot, anthracnose, red spider, ants, snails and other diseases: long-term excessive drying of the basin soil leads to slow growth or even death of orchid plants due to lack of water and fertilizer. Soak and water once every two months, usually once a week or two, and spray the leaves, ground and related utensils every day according to the wet and dry conditions.

temperature

Orchids can grow at 5-30℃, and the ideal temperature for the fastest growth and development is 1-25℃. The balcony should open and close the doors and windows in time according to the season and daily weather changes, keep the air fresh and keep the temperature and humidity. The general principle is to close the day and open the night, open the house in hot and cold, and drive comfortably, so that the temperature can be controlled artificially and the temperature difference can be increased, and the rainstorm can be prevented in winter, the ice can be prevented at night, and the heatstroke can be prevented during the day in summer.

humidity

The ideal humidity for orchid growth is 70%-80% relative humidity. Orchids on the balcony are easy to dry, so it is necessary to keep the air humidity on the balcony close to the range that orchids like. There are two simple ways to control humidity. First, no matter whether the flowerpot is hung or placed vertically, a water storage basin should be placed under it, which can not only humidify, but also maintain indoor hygiene. It can also be placed on the balcony after the flowerpots and buckets are filled with water, and it can also achieve long-term moisturizing effect. Second, according to the weather changes, spray flower water every day, once in the morning and evening when it is hot and dry in spring and summer, and once every day in spring and autumn to ensure air circulation in rainy days. The quantity and range of spraying depend on the wet and dry conditions. When it is particularly dry, spray not only leaves and flower pots, but also the ground, related items and even the wall.

Fertilize soil or land

Thin application of chemical fertilizer is the key to fertilization of orchids. Orchids grow slowly and will not wither.

prevent disease

The balcony is far away from the ground, ventilated and full of light. As long as pests and diseases do not enter the gateway with orchids, fertilization is reasonable, watering requirements are well controlled, and humidity is well controlled, pests and diseases are generally not easy to occur. However, balcony orchids do not grow in a vacuum, and necessary prevention is also indispensable. From early summer to late autumn, carbendazim, thiophanate, chlorothalonil, etc. You can spray it once or twice in the rainy season, which is basically foolproof.
