There's an art to letting orchids get rained on; keep these precautions firmly in mind
Huangyan premium plum-petal -- Shentao, has rebloomed many times, and its flower quality is extremely stable. From small bud arrangement to large bud arrangement to full bloom, it took 20 days. From the first flower opening to the top flower fully opening, it took nearly a week. The time was a bit short, and the flower spike did not elongate. The flowers are somewhat crowded, possibly due to the weather alternating hot and cold and the plant being unaccustomed to the new environment. Overall, the bloom quality is still...
1. Places with good air quality are suitable for rain exposure, while areas with severe pollution should be avoided.
The original native habitats of orchids have fresh air, and orchids thrive under the nourishment of rain and dew. After being collected from the mountains and potted, because climates vary greatly from place to place and air quality differs widely, whether orchids can receive nature's baptism of rain and dew should be treated differently. In areas with good air quality, orchids may appropriately be allowed to get rained on during the rainy season, as the nourishment of rain and dew makes orchid seedlings strong; but in places with severe air pollution, where acid rain is more common, letting orchids get rained on very easily leads to various diseases, with a hundred harms and not a single benefit, so orchids getting rained on should be resolutely avoided.
2. Gentle breezes and fine rain are suitable for rain exposure, while "sun showers" and violent storms should be avoided.
In places with good air quality, what suits orchids best for rain exposure is long-lasting gentle breeze and fine rain; after the rain clears, the orchid seedlings are especially vigorous and grow rapidly; during the growing season, orchids are most afraid of "sun showers" and violent storms in high-temperature seasons. The so-called "sun shower" refers to short thunderstorms in summer when it alternates between clear and rainy. This kind of rain comes swiftly and lasts a short time, and often heat accumulates in the pot without dissipating while the scorching sun is again overhead, very easily causing new shoots to rot at the heart and orchid roots to suffer steaming and develop disease. When encountering a "sun shower," orchid growers should promptly irrigate the orchids so that the summer heat in the pot dissipates at once, and strengthen ventilation to dry the water in the leaf hearts of new shoots as quickly as possible. Violent storms in high-temperature seasons easily snap and batter orchid leaves, splashing pot mud onto orchid leaves and into leaf hearts, often causing disease spots on orchid leaves and heart rot in orchids. Therefore, whenever violent storms occur, measures should be taken quickly to shield orchids from wind and rain.
3. Healthy seedlings are suitable for rain exposure, while diseased seedlings should be avoided.
Practice has proven that in places suitable for rain exposure, letting robust orchids bathe in rain and dew makes the orchid seedlings grow stronger day by day; but for diseased seedlings the effect is the opposite, and the more they are exposed to rain, the more severe the disease becomes; for diseased seedlings it is better not to expose them to rain.
