How often to water orchids
As one of China's top ten famous flowers, orchids are deeply loved by gardening enthusiasts for their elegant temperament. Mastering scientific watering methods can not only extend the blooming period but also prevent root diseases. This article will systematically analyze the watering rules for all seasons, combined with 20 years of gardening experience, to reveal the secrets of keeping orchids fresh and vibrant.
Orchid watering guide for all seasons
Spring growth promotion watering plan
From March to May, when the temperature rises to 15-25℃, orchids enter a rapid growth period. It is recommended to use the pot immersion method, fully soaking the planting material 2-3 times a week, and complementing morning leaf misting to maintain an environmental humidity of over 60%.
Summer high-temperature补水 strategy
From June to August, a double protection system needs to be established: water thoroughly every morning and supplement half the amount of watering in the evening. Special attention should be paid to avoid watering during the high-temperature noon, and碎 tree bark can be used to cover the surface of the planting material to reduce water evaporation.
Autumn moist period regulation
From September to November, when the air humidity increases to 70%, the watering interval can be extended to 3-4 days. It is recommended to use the bamboo stake test method: insert the bamboo stake into the planting material for 3 minutes, and if the tip is slightly damp, there is no need to water.
Winter dormancy period maintenance
From December to the following February, when the temperature is below 10℃, slowly inject 200ml of water along the pot wall every 10-15 days. Using warm water at 25℃ can prevent low-temperature frostbite while maintaining the planting material slightly dry.
Scientific orchid watering methodology
Environmental variable control principle
Outdoor maintenance requires the installation of a transparent rainproof shed and immediately check the moisture of the planting material after rain. It is recommended to set up a drainage layer (a mixture of ceramsite and pine bark 1:1), allowing the water in the pot to drain within 30 seconds.
Planting material adaptation system
For different characteristics of the planting material: sphagnum moss has strong water retention and requires a 20% reduction in watering, while volcanic rock substrates need a 30% increase in watering frequency. It is recommended to retain 1/3 of the old planting material when repotting each year to maintain the balance of the microbial community.
By establishing a three-dimensional maintenance model of season-environment-planting material, combined with precise humidity monitoring, the survival rate of orchids can be increased to over 95%. It is recommended to use a temperature and humidity meter for data recording, forming a personalized watering calendar to keep the elegant posture of orchids throughout the year.
