Which kind of orchid is the best to remove formaldehyde?

There are many kinds of hanging orchids, including Phnom Penh, Golden Heart, Silver, Silver, Broad-leaf, Middle spot, Milky White and so on. These hanging orchids are just different in appearance, but they are all the same plant species. To say which kind of hanging orchid has the best effect of removing formaldehyde, in fact, the effect of removing formaldehyde of these hanging orchids is about the same, but except formaldehyde can not pin all hopes on plants, after all, the speed of removing formaldehyde of hanging orchids is relatively slow.

What are the common varieties of orchids?

1. Phnom Penh Cymbidium: Phnom Penh Cymbidium leaves are broad linear, tender green, born on short stems, with fat cylindrical fleshy roots, racemes, curved drooping florets, white florets, and often produce clusters of rooted plantlets formed by plant buds on flower stems, which is very interesting.

2. Silver-edged Cymbidium: the edge of the leaf is white, racemes, flowers are small, white, with rhizomes and fleshy roots. Like warm, moist, semi-shady environment, cold tolerance is poor, should be well drained, fertile sandy soil to grow.

3. Golden orchid: the leaves of Magnolia are slender, linear-lanceolate, with yellow-white longitudinal stripes in the center, clasping at the base, bright green. Leaf axils draw creeping branches, protruding clumps of plants, bending outward, apically bearing small plants with aerial roots. Flowers white, perianth 6.

4. Magnolia: Cymbidium is native to southern Africa. Like warm, humid and semi-shady environment, leaves are particularly sensitive to light, summer is afraid of strong light, soil is suitable for loose and fertile loam, good water retention, winter temperature is not lower than 10 ℃.

How does the hanging orchid grow well?

1. Lighting: hanging orchid likes semi-shady environment and is very sensitive to light. When the sun shines directly in summer and autumn, the leaves will wither and yellow, and even the whole plant will die. In winter, because the sun is not strong, we can let the orchid accept some direct sunlight properly.

2. Temperature: hanging orchid likes warm and humid climate, can not tolerate severe cold and heat, the optimum growth temperature is 15: 25 ℃, and the room temperature in winter should not be lower than 5 ℃. Avoid strong light in high temperature, but see more sunshine in low temperature and cold.

3. Watering: Diaolan likes water, has strong drought resistance, and needs more water during the peak growth period from March to September, so it should be watered and sprayed frequently to keep the basin soil completely moist. In the winter dormant period, you can wait until the surface of the basin soil is about 1 cm deep dry before watering.

4. Fertilization: Cymbidium is a more fertilizer-tolerant plant. If there is not enough fertilizer and water, it is easy for the scorched head to grow old, and the leaves turn yellow and lose its ornamental value. For those who have begun to grow small plants, nitrogen fertilizer is applied once every half a month, and those with good growth are not allowed to apply nitrogen fertilizer.

5. Soil: hanging orchid should use light and fertile sandy loam, which requires that the soil contains humus and strong permeability. Potted plants can use rotten leaf soil or peat soil, garden soil and river sand mixed with a small amount of base fertilizer as the substrate.

6, change the basin: the hanging orchid should change the basin once every March, if the basin is deeper and the base fertilizer is enough, it can be changed once every two years. When turning the pot, knock the plant out of the basin, cut off the withered roots and excess roots, replace it with new culture soil and apply sufficient base fertilizer.

7, diseases and insect pests: hanging orchid is generally not easy to occur diseases and insect pests, the occurrence of diseases is generally stagnant water in basin soil, poor ventilation caused by root rot and root rot, should be timely spray control. The dense plant clusters are poorly ventilated and are vulnerable to scale insects, so prevention should be given priority to.

8. Pruning: the orchid should cut off the yellow leaves at any time and turn the basin once a year in March to cut off the old root, rotten root and excess fibrous root. The old leaves of Cymbidium can be cut off in the first and middle of May, which will promote the germination of more new leaves and small Cymbidium.
