How to manage orchids in spring

The key points of orchid management in spring are as follows: plant protection and re-watering; frequent ventilation; turning basin and pruning plants to supplement nutrients; insecticidal and bacterial control with the increase or decrease of temperature. These words orchid friends carefully understand their own meaning, including the major points of spring orchids.

1. Leaving the room should be determined by the local temperature and should not be followed by the article. There is a difference in temperature between the north and the south, and there is a late spring cold in the north, so it is better to leave the room later than in the south. The spring of the orchid art world is aimed at the north. In the north, it is recommended that the temperature should be stable above 1820 degrees after the Qingming Festival. The first is to prevent the cold in spring, and the other is to avoid leaving the room late to affect the growth trend.

Do not rush out of the room, the orchid is sensitive to sudden changes in the environment, must be adapted in advance, outdoor ventilation and light is incomparable to the indoor environment in winter. Therefore, the window should be opened in advance to adapt to the orchid for a few days before leaving the room, so that the orchid plant has a gradual adaptation process.

2, plant protection run, re-watering: the temperature in early spring is still unstable, mostly low, with this orchid product is still dormant, water transpiration is still slow, there is little demand for water, watering should not be dry or irrigated. But for Cymbidium, which is about to blossom, and Cymbidium, which is already pregnant, watering should be more frequent according to demand. Water less after flowering to prolong the flowering period. After the flower fades, the water should be properly controlled, and it is appropriate to keep the basin soil moist. You can increase watering when the temperature rises and stabilizes, that is, you can increase watering when you have to reduce your winter clothes, but the increase only means that the basin soil is transpirating faster, and the watering frequency should be increased rather than letting you keep the basin soil wet all the time.

3, ventilation, when the temperature rises to 20 degrees, bacterial diseases and insect pests become active, indoor people do not open windows have been uncomfortable breathing, orchids even more so. At this time, we should increase the window ventilation frequency (rainy or cold wind on cloudy days or not), and it is appropriate to have sunny days.

4, spring bathes the sun and everything is long. Spring sunshine makes people lazy and comfortable, especially for plants. Spring sunlight has activating elements and growth elements that stimulate all living things in spring dormancy, which is also the reason for plant sprouting in spring. Therefore, the light in spring must not be ignored. If you can get more sun, you can make sure it is enough.

5. Spring is the best season for turning the basin and pruning the whole root. If the basin is divided into pots, nutrients should be replenished. It should be noted that Cymbidium, Cold Orchid and Cymbidium are gregarious, and it is better to divide the pot with more than 3 seedlings. Keep in mind when fertilizing: in winter, orchid plants inevitably have diseases. Fertilization should grasp the application of good roots and strong seedlings, but not the poor ones of root injury seedlings. The principle of topdressing is less than more and thinner than thick. Langan just woke up, sleepy eyes must remember the big fat tonic.

6. The outbreak period of diseases and insect pests begins from March to May in spring. This is true not only for orchids, but for all indoor flowers! Temperature above 16 degrees began to check plant diseases and insect pests, basin soil can not be let go. There will be drug damage reaction due to high temperature above 25 degrees, it is better to spray sooner or later. When spraying, it is best to open the window. Any drug damage has a pungent and harmful smell to those without protective tools. I once had an experience of dizziness, itching, dry sore throat and almost fainting without a mask when I was filled with flowers. The most harmful part of this kind of drug is the throat.
