In the early spring, it is reported that the flowering period of the blue and Chunlan flowers is also the budding period of Jianlan and Hanlan. In early spring, there are many rainy and cloudy days, the temperature changes greatly, and it is easy to reappear cold waves, which is extremely detrimental to the growth of orchids. At this time, such as poor management, it will lead to rotten orchid roots, bad buds, even when the flowering period is reported to blue, Chunlan burnt. Therefore, the management of orchids in early spring is very important.
In response to the erratic, cold and rainy conditions of the early spring season, we must place indoor management to protect the scapes and flowers for the flowering period's reporting to Lanhua and Chunlan, because the rainy and cold changing weather will shorten the flowering period, and the orchids will be poured into cold rain. Causes the flowers to rot. For orchids such as Jianlan and Huanlan, they can be stored outdoors, but care must be taken to prevent the water from falling on the blue pots.
In early spring, orchids should avoid all fertilizers. At this time, the basin soil should maintain a slightly wet state, otherwise the sprouts of Jian Lan and Cang Lan will be crushed to death, commonly known as "black death", and the orchid buds will decay into dark brown. It has been extended until the whole bud is brown and dead. The death of spring buds will seriously affect the growth, reproduction and flowering of the whole potted orchid plant. As the saying goes: Spring buds, weak summer buds, and improper autumn buds. If the spring buds rot, then no new seedlings will grow strong.
In spring, the weather is a period of frequent occurrence of various diseases and insect pests. Snails, aphids, scale insects, and ground tigers, crickets and other pests began to damage orchids and sprouts; rainy and humid weather will aggravate brown spot disease. Therefore, spray 65% â€‹â€‹thiophanate or 50% carbendazim 1000 times on a regular basis. Be sure to keep it clean around the pots. Dispense quicklime to prevent pests from invading the basin wall and drain holes into the basin. Always check the orchid basin. There is no pest or disease. For those who have already spent the flowering season, they should timely make up the fertilizer, but avoid applying concentrated fertilizer.
