Can lotus plants withstand rain?
As a typical aquatic flower, the growth of lotus plants is closely related to the water environment. Many horticulture enthusiasts often have questions about the impact of rain on lotus plants and water standards. This article will systematically elaborate on the symbiotic relationship between lotus plants and water, helping you create an ideal growing environment for lotus plants.
Lotus plant care when exposed to rain
Benefits of natural rain exposure
Lotus plants in open-air ponds are nourished by natural rain for a long time. The trace elements in rain can promote the differentiation of flower buds, and the continuous water flow can effectively remove dust from the leaves, enhancing the efficiency of photosynthesis. Observations show that lotus plants that experience light rain have an average increase in height of 15%-20%.
Protection during special periods
Newly transplanted lotus plants should be protected from heavy rain. It is recommended to use a 50-mesh shade net to create temporary protection. When rainfall exceeds 30mm/h, a drainage system should be activated to prevent waterlogging of new leaf buds. Potted lotus plants can be temporarily moved to a covered area, and reset after the rain subsides.
Lotus plant water management system
Water level control standards
When growing in containers, maintain a water level of 5-8 cm, ensuring that the base of the leaves is more than 3 cm from the water surface. For water tank cultivation, it is recommended to use a graded watering method: germination stage 5 cm → leaf expansion stage 10 cm → flowering stage 15 cm, maintaining a water level of 2 cm during the winter dormant period.
Water quality optimization plan
Pond water should be settled for 3 days before use, and tap water is recommended to be aerated for 72 hours. Add EM bacterial solution (at a ratio of 1:500) monthly to maintain microbial balance. Change the water immediately when the water transparency is below 20 cm.
Water temperature adjustment techniques
Maintain a water temperature of 18-25℃ in spring and autumn, control the water temperature not to exceed 32℃ in summer by shading, and use double-layer containers to insulate in winter. The temperature difference between new and old water during water replacement should be less than 3℃, to avoid sudden temperature changes that cause dormancy disorders.
Scientific water management is a core element for the healthy growth of lotus plants. By simulating the natural water environment, combined with regular water quality testing (it is recommended to test the pH value of 6.0-7.5 and EC value of 0.8-1.2mS/cm monthly), and seasonal care adjustments, you can cultivate high-quality lotus plants with green leaves and upright flowers.
