Why Don't White手掌 Blossom
As a widely popular ornamental leaf and flower plant, the White手掌 is loved by many for its elegant white spathe. However, it is common to encounter problems such as not blooming or the flowers turning green in actual maintenance. This article, through systematic analysis and illustration, helps you fully grasp the key points of caring for White手掌.
Three Main Reasons for the Non-Blooming of White手掌
Immature Seedling Age Affects Flower Bud Differentiation
White手掌 needs to go through more than 3 years of vegetative growth to have the ability to bloom, and blooming in the seedling stage is a rare event. It is recommended to judge the maturity of the plant by observing the lignification of the stems and wait patiently for the blooming period to arrive.
Typical Manifestation of Nutritional Imbalance
A phosphorus and potassium fertilizer enhancement program should be implemented 60 days before the blooming period: apply potassium dihydrogen phosphate solution (1:1000) to the roots and foliar spray every week, combined with decomposed sheep manure organic fertilizer as a base fertilizer. Special attention should be paid to avoid excessive nitrogen fertilizer, which can cause leaf elongation.
Key Points of Light Regulation
During the flower bud differentiation period, ensure 4 hours of scattered light exposure per day, which can be achieved by setting up a shading net to achieve 50% light intensity. Avoid direct sunlight from 10:00 to 15:00 in summer, and full sunlight can be accepted in winter.
Strategies for Dealing with Greening of White手掌 Flowers
Recognition of Physiological Color Change
It is a normal metabolic phenomenon for the flowers to turn green 15 days after blooming. At this time, the spathe will show a gradual green texture. It is recommended to keep the flower stem until it withers completely, avoiding early removal that affects nutrient recovery.
Remedial Measures for Light Compensation
When new flowers appear green, immediately move the plant to an east-facing windowsill, maintaining a light intensity of 2000-3000Lux for 5-7 days. Rotate the pot to ensure even light exposure, allowing the flower color to return to pure white.
By precisely controlling temperature and humidity (daytime 25°C/nighttime 18°C, humidity 60%-70%), regularly replacing slightly acidic substrates (pH 5.5-6.5), and properly pruning old leaves, the quality of White手掌 blooming can be significantly improved. It is recommended to add breathable media such as pine bark when repotting in spring every 2 years to ensure healthy root development.
