How to Make Rain Lily Bloom More
The rain lily is loved by gardening enthusiasts for its characteristic of blooming after the rain, but many flower friends often encounter problems such as few flowers and difficulty in reblooming. This article will systematically analyze the complete care cycle of rain lilies, from flowering techniques to post-flowering management.
One, Three Core Elements of Rain Lily Explosion Flowering
1. Scientific Soil Mixing and Close Planting Techniques
Choose a breathable ceramic pot with a diameter of 25cm or more, use the golden ratio of "coarse sand: peat: garden soil = 3:4:3," and add 10g of bone meal as a base fertilizer per liter of soil. Keep the bulb spacing at 3-5cm for close planting, and planting 8-10 bulbs in each pot can create a competitive flowering effect.
2. Light, Water, and Temperature Collaborative Management
Ensure 6 hours of direct sunlight in spring and autumn, and 30% shading in summer. Stimulate flowering through the "dry-wet cycle": after the potting soil is completely dry, water thoroughly with 4°C ice water to activate dormant bulbs. Maintain nighttime ventilation during high temperatures above 30°C, which can effectively extend the flowering period of a single flower by 3-5 days.
3. Precise Fertilization Plan
Apply a water-soluble fertilizer with N-P-K 15-30-15 every half month during the growing period, and add potassium dihydrogen phosphate (800 times liquid) during the budding period. Topdress with decomposed sheep manure fertilizer in September to enhance bulb energy storage for wintering, which can increase the number of flowers the following year by 40%.
Two, Post-Flowering Fine Management System
When the remaining flowers start to wilt, immediately cut obliquely from 2cm below the base of the flower stem and simultaneously supplement chelated calcium fertilizer to promote wound healing. Perform division every 2 years: separate the mother bulb with 3-4 daughter bulbs as a unit, retain more than 15cm of fibrous roots, soak in carbendazim before planting in new soil. Place the divided plants in a diffused light environment for 7 days to slow down the seedlings, which can shorten the reblooming cycle by 30%.
By using scientific flowering methods combined with post-flowering management, rain lilies can bloom 4-6 times a year. The key is to grasp the growth rhythm of bulbous plants, create moderate environmental stress to stimulate flowering potential, and配合 nutritional management to form a virtuous cycle, making your rain lily truly a "flowering machine."
