There are five tips for orchids to tell you how to keep it well.

Orchid and plum blossom, daffodils, chrysanthemum and become four elegant flowers, is one of the top ten famous flowers in China. Since ancient times, orchids have been regarded as the "embodiment of righteousness" and the symbol of auspicious and beautiful food in the world. It is not easy to raise a pot of orchids, so let's take a look at what matters needing attention.

Notes on the culture of orchids

① temperature

Keep it indoors in winter.

② humidity

Orchids grow well when the air relative humidity is 60-70%. Too dry or too wet can easily cause orchid disease. Therefore, outdoor cultivation should create a humidity microclimate suitable for orchid growth, and indoor sprayers and hygrometers should be installed.

③ illumination

Orchids like yin and fear the sun. In summer, they can let the sun shine directly on the orchid leaves before 07:00. After 07:00, they can block the sun with a 50% Murray shading net. Before and after the Qingming Festival, orchids can bask in the sun more, promote roots and send more leaf buds. After White Dew, the weather turns cool and most of the new grass grows. It can also shine more sunshine to make the buds full, so that the orchid plants can accumulate more nutrients to facilitate their growth in the coming year.

④ watering

Orchids like rain and fear to be scrawled, happy and moist and afraid of wetting. When the leaf buds of orchids extend about 1.5 cm from June to July, thin and rotten liquid fertilizer can be applied 1-2 times (chemical fertilizer is not suitable). From August to September, 1-2 times of mature and thin liquid fertilizer were applied. The plant ash extract of vegetarian orchids can be applied for 1-2 times, and the effect is very good. The best time to fertilize is in the evening, and water again the next morning.

⑤ fertilizer

Orchids like light, fertilization is better light than thick. Like other plants, nitrogen can promote the growth of stems and leaves. Phosphorus can promote the development of orchid root, promote the development of reproductive organs, and stretch the stems and leaves. Magnesium, sulfur, iron and other trace elements can make leaves green and flowers strong.

More fertilizer should be applied during the peak growth period of orchids, but not during dormant or weak growth periods. If excessive fertilization, the roots and leaves will be burned, resulting in irreparable losses.

Matters needing attention in raising orchids

1, the pot is not too large-small plants grow in large pots, the amount of plant material is large, it is easy to lead to poor ventilation, watering is not easy to control. If watering absorbs too much water, the plant material is not easy to dry, and bacteria invade and cause rotten roots.

2. Orchids should be planted shallowly-do not plant orchids too deep, otherwise long-term moisture will rot. When planting, filling the root, base, or pseudobulb must be exposed.

3. The roots should be unfolded-when planting orchids, the roots should be evenly expanded and should not be squeezed together, so that each root can touch the plant material and ventilation is good.

4. No watering for several days-the roots of newly planted orchids may be injured, and the wound is coated with fungicides, which can not be watered for 3-5 days to achieve efficacy and promote the growth of new buds and roots.

5. Avoid strong light-newly planted orchids must avoid direct sunlight to prevent dehydration. They should be placed in a warm and shady place, and spray can be used to increase the humidity in the air until the orchids return to normal growth.
