What's the deal with green flowers appearing on 'Yifan Shunshun'
As a widely popular indoor foliage plant, 'Yifan Shunshun' (Peace Lily) is adored for its pure and elegant white flowers. When the flowers turn from white to green, many plant enthusiasts may feel puzzled. This green flower phenomenon could either be a natural growth pattern or indicate a cultivation issue, which requires a judgment based on specific conditions.
I. Analysis of the Causes of the Green Flower Phenomenon
1. Natural Metabolic Characteristics
The lifecycle of Peace Lily flowers lasts about 2 months, with a natural fading occurring at the end. When the chlorophyll concentration in the sepals exceeds that of anthocyanin, the flowers will show a gradient from light green to dark green, which is a normal phenomenon in the plant's life cycle (S-Y) division.
2. Manifestations of Light Imbalance
When plants are exposed to a low light environment of less than 1000 lux (typical indoor lighting is about 500 lux) for an extended period, they increase chlorophyll to enhance light energy utilization. It is recommended to use a professional light meter to maintain a scattered light intensity of 2000-3000 lux.
3. Abnormal Nutrient Supply
Flowering requires a large amount of phosphorus and potassium elements. When the soil EC value is less than 0.8 mS/cm, there will be a nutrient deficiency. It is recommended to use a water-soluble fertilizer with an NPK ratio of 1:2:1, and complement it with a monthly application of 5g of decomposed sheep dung organic fertilizer.
II. Systematic Treatment Solutions
Take分级 treatment (graded treatment) based on different causes: promptly prune naturally aging flowers to 1 cm from the base; for plants with insufficient light, use a progressive lighting method, adding 30 minutes each day until reaching 4 hours of light; for plants lacking fertilizer, follow the principle of 'apply thin fertilizer frequently', supplementing with an 800-fold diluted potassium dihydrogen phosphate solution weekly.
By establishing a three-dimensional maintenance system of 'environmental monitoring - symptom judgment - precise intervention', and rotating the flowerpot regularly to ensure even light exposure, the green flower phenomenon can be effectively prevented. It is recommended to conduct root inspections quarterly, maintain a slightly acidic soil environment with a pH of 5.5-6.5, and allow your Peace Lily to continue blooming with elegant white flowers.
