Management details of Orchid in early Spring

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 buds will seriously affect the growth, breeding 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.
