Will chrysanthemums wilt after getting rained on? How to prevent damage from rain?

Does chrysanthemum fear rain?As the most representative ornamental plant in autumn, the maintenance and management of chrysanthemum often cause confusion among horticulture enthusiasts. Especially in rainy seasons, whether the plant can withstand the test of rain becomes a key issue. This article systematically elaborates on the relationship between chrysanthemum and rain through scientific analysis combined with practical experience.Analysis of chrysanthemum's rain resistanceCharacteristics of plant structureAlthough chrysanthemum has the flexibility of herbaceous plants, its dense petals and expanded inflorescences form a natural water storage structure. When encountering continuous rainfall, this physiological feature becomes a burden, easily causing bud mildew.Root oxygen requirementThe roots of chrysanthemum require a higher soil oxygen content, and its fleshy roots will show signs of suffocation within 24 hours in a waterlogged environment. The limited root characteristics of potted chrysanthemum further exacerbate the damage caused by accumulated water.Rain damage classification and managementResponse to short-term light rainFine rain lasting less than 2 hours, combined with well-drained sandy loam soil (recommended proportion: river sand 40% + humus soil 60%), can effectively maintain root health. In this case, it can be kept in its natural state, and the soil should be loosened properly after the weather clears.Protection against continuous heavy rainHeavy rain lasting more than 6 hours requires immediate protective measures. In addition to transferring to avoid rain, it is recommended to support the inverted plants with bamboo stakes, use the siphon method to drain the accumulated water in the pot, and remove the damaged buds.Post-disaster recovery planFlooded plants need to undergo three-step repair: first, tilt the pot to drain excess water, second, insert holes in the soil layer with bamboo skewers to increase oxygen, and finally, pour a 0.1% indole butyric acid solution into the roots to promote new root growth. The treated plants should be placed in a ventilated and shady place for 7-10 days of care.Through scientific management, chrysanthemum can maintain a good growth momentum during the rainy season. It is recommended to take protective measures in advance based on weather forecasts, choose breathable ceramic pots for cultivation, and use shelters during the bud stage to enjoy the beauty of chrysanthemum in autumn frost while avoiding rain damage.
