What to Do When Chlorophyllwilting in Spider Plant
The spider plant, a common indoor green plant, has been困扰ing many plant enthusiasts with its chlorophyllwilting problem. This article systematically analyzes the causes of chlorophyllwilting in spider plants through four core maintenance points and provides professional solutions, complemented by real-shot illustrations to help you quickly diagnose plant issues.
Spider Plant Repotting Techniques
The Importance of Regular Repotting
Spider plant roots are well-developed, and after two years without repotting, the roots may entwine into a mass, leading to soil compaction and nutrient depletion. It is recommended to change to a pot one size larger every March, using a mixture of decomposed leaf soil and perlite (3:1). If the original pot has sufficient soil fertilization, repotting can be extended to once every two years.
Repotting Steps
Stop watering 3 days before repotting to allow the soil to dry, then gently tap the pot to remove the plant. Trim blackened and rotting roots, keeping healthy white rootlets. Place a 3cm layer of ceramic stones at the bottom of the new pot, put the plant in when the soil is one-third full, and gently press the soil to secure the plant.
Key Points for Light Management
Controlling Light Intensity
Spider plants grow best under 3000-5000 lux light conditions. Direct sunlight in summer can cause the leaf surface temperature to exceed 35°C, accelerating transpiration and causing leaf dehydration. It is recommended to use a shading net to filter 50-70% of the intense light, or place the plant 1 meter away from an east-facing window.
Adjusting Light Duration
Maintain 4-6 hours of scattered light daily during spring and autumn, and extend to 8 hours in winter. When using a lux meter, if the value exceeds 8000 lux, shade the plant immediately.
Scientific Fertilization Methods
Suggestions for Fertilizer Ratio
During the growing season (May-September), use N-P-K 20-20-20 water-soluble fertilizer, diluted to 1500 times liquid, applied weekly. In case of fertilizer damage (leaf tip scorching), immediately flush the roots with water 3 times, then stop fertilizing for 30 days and switch to 3000 times liquid to resume fertilization.
Organic Fertilizer Alternative
Fermented soybean cake fertilizer can be mixed with water at a ratio of 1:50, watered every half month. Combine with foliar application of 0.1% potassium dihydrogen phosphate solution to enhance leaf resistance.
Precise Watering Strategy
Controlling Dry-Wet Cycle
Use the "dry-then-wet" method: water thoroughly when the top 2cm of soil is dry. In summer, when evaporation is high, use a saucer water accumulation method to maintain humidity above 60%. In winter, control water to keep the potting mix half-dry to prevent root rot.
Water Treatment Skills
Use tap water that has been exposed to sunlight for 3 days, ensuring the water temperature matches the room temperature. Rinse the leaf surface with rainwater or purified water monthly to remove salt crystallization and keep the stomata unobstructed.
Through systematic maintenance and management, spider plants usually recover within 30 days. It is recommended to keep a maintenance log, recording repotting dates, fertilizing cycles, etc., and adjust the maintenance plan in time based on the plant's condition to restore the spider plant's lush green vitality.
