How to care for newly bought Nephrolepis cordifolia
As a颜值担当 among ferns, Nephrolepis cordifolia is deeply loved by gardening enthusiasts for its delicate and elegant leaf shape. Newly acquired Nephrolepis cordifolia often experiences leaf burning and growth stagnation due to sudden environmental changes. This article will systematically analyze the key points of cultivating new Nephrolepis cordifolia seedlings from environmental regulation to daily care.
Key care during the acclimatization period of Nephrolepis cordifolia
Environmental adaptation strategy
Newly purchased Nephrolepis cordifolia needs to go through a 7-10 day acclimatization period, maintaining a constant temperature of 20-25°C, and the recommended air humidity is 60%-70%. You can use the pot-in-pot method (an inner pot nested in a moisture-retaining outer pot) or timed atomizing humidification to avoid积水 on the leaf surface by direct watering.
Light adjustment plan
Adopt a progressive lighting adaptation method: place it near the north-facing window (800-1500lux) for the first 3 days, and gradually move it to an east-facing diffused light environment (3000-5000lux) from the 4th day, avoiding direct midday strong sunlight.
Systematic care plan for Nephrolepis cordifolia
Three elements of micro-environment regulation
1. Temperature and humidity management: Establish a day-night temperature difference gradient (day 22-25°C / night 18-20°C), combined with a double-layer tray moisture retention method (3cm spacing between the lower water storage layer and the upper planting layer) 2. Water and fertilizer balance: Use the immersion pot method for water supply (2 times per week / 15 minutes each time), combined with chelated iron foliar fertilizer (1:2000 once a month) 3. Ventilation guarantee: 1 hour of air circulation in the morning and evening, using a circulating fan to maintain a gentle breeze environment of 0.3-0.5m/s
Advanced cultivation techniques
• Substrate ratio: Peat soil: Perlite: Pine bark = 5:3:2, supplement 5% bone meal every half a year • Disease prevention: Apply Bacillus subtilis (1g/liter of water for root irrigation) every month • Shaping pruning: Use a 45-degree oblique pruning method to remove old leaves, retaining a 5-7cm petiole to promote new buds
Standard operation for potting Nephrolepis cordifolia
The best time for repotting is before the spring sprouting, using a red pottery pot (30% better breathability than plastic pots) and retaining 1/3 of the original soil to protect the roots. After repotting, implement the "three no" principle: no fertilizing, no repositioning, no pruning within a week, and return to normal care after the new leaves unfold.
By precisely controlling light, temperature and humidity, and scientific fertilization, the survival rate of newly acquired Nephrolepis cordifolia can be increased to over 95%. Regularly observe the development of spores on the back of leaves (mature spores are brown), collect them in time to achieve propagation and expansion. It is recommended to establish a care log, recording daily environmental parameters and plant conditions, and gradually master the individual growth rhythm of Nephrolepis cordifolia.
