How to maintain orchids in early spring

Orchid (scientific name: Cymbidium ssp.): epiphytic or terrestrial herbs, with several to many leaves, usually on the base or lower nodes of pseudobulbs, distichous, banded or rarely oblanceolate to narrowly elliptic, base generally with broad sheaths and enclosing pseudobulbs, articulated. Racemes with several or many flowers, the colors are white, pure white, white-green, yellowish green, yellowish brown, yellow, red, cyan, purple. Orchids in traditional Chinese flowers only refer to several species of terrestrial orchids distributed in Chinese orchids, such as Chunlan, Huilan, Jianlan, Mulan and Hanlan, which are commonly referred to as "Chinese orchids". This kind of orchid is very different from the tropical orchid with large and colorful flowers, there is no eye-catching gorgeous state, no huge flowers and leaves, but it has a simple, quiet, elegant and elegant temperament, which is very in line with the aesthetic standards of the Oriental. It has been cultivated in China for more than a thousand years.

Early spring is the blooming period of orchid and spring orchid, and it is also the budding period of Jianlan and Han orchid. It is cloudy and rainy in early spring, the temperature changes greatly, and it is easy to appear cold wave repeatedly, which is extremely disadvantageous to the growth of orchids. At this time, such as poor management, it will lead to rotten roots and buds of orchids, and even rotten flowers of orchids and spring orchids in full bloom. Therefore, the early spring management of orchids is very important.

In view of the changeable, cold and rainy weather in early spring, orchids and spring orchids in full bloom must be placed for indoor management to protect scape and flowers, because rainy and cold and changeable weather will shorten the flowering period, and orchids will rot when they are watered with cold rain. For orchids such as Jian Lan and Han Lan, you can put them outdoors, but you must pay attention to the drainage and waterlogging of the orchid basin, preferably with a plastic film above the orchid basin to cover the rain.

In early spring, orchids should avoid all fertilizers. At this time, the basin soil should be kept slightly wet, otherwise the new buds of Jian Lan and Han Lan will rot to death, commonly known as "black death", and the tip of the orchid bud will rot into dark brown. It extends until the whole bud is brown and dead. The rotten spring bud will seriously affect the growth, reproduction and flowering of the whole orchid plant in the same year. As the saying goes: spring buds are prosperous, summer buds are weak, autumn buds are improperly counted. If the spring buds are rotten to death, they will not get vigorous new seedlings in that year.

The overcast weather in spring is a frequent period for all kinds of diseases and insect pests. Snails, aphids, shell insects, ground tigers, mole crickets and other pests began to harm orchid plants and new buds; rainy and wet weather will aggravate the occurrence of brown spot. Therefore, 65% topiramine or 50% carbendazim 1000 times solution should be sprayed regularly, keep clean around the orchid basin, spread quicklime to prevent pests from drilling into the basin from the hydrophobic holes in the basin wall and bottom, and regularly check the orchid basin for the occurrence of diseases and insect pests. For orchids and orchids that have passed their flowering period, they should be fertilized in time, but do not apply thick fertilizer.
