How to care for Huang Chan
The golden flower瀑布-like Huang Chan always becomes the focus of the courtyard, but to keep it blooming continuously requires mastering scientific care methods. As a typical tropical ornamental plant, Huang Chan has unique requirements for its growing environment. This article will systematically analyze the key points of care from five dimensions to help you create a flourishing scene.
One, Key Points for Huang Chan Growth Substrate Configuration
1.1 Golden Rule of Soil Proportioning
It is recommended to use a potting mix of peat soil: perlite: decomposed pine needles = 5:3:2 for Huang Chan. This mixed substrate can ensure nutrient supply and has good breathability. Add 200g of bone meal + 100g of slow-release fertilizer as a base fertilizer for every cubic meter of soil, and disinfect the soil with a carbendazim solution before planting.
1.2 Precise pH Control
Huang Chan grows best at a pH range of 5.5-6.5. You can test the pH value monthly with pH test paper. When the value is >7, you can water with a diluted 1000-fold solution of ferrous sulfate; when the value is <5, sprinkle a small amount of wood ash to neutralize acidity.
Two, Light and Temperature Coupling Management Plan
2.1 Light Intensity Grading Management
Full sun care in spring and autumn, 30% shading from 10:00 to 15:00 in summer, and ensuring 5 hours of direct sunlight in winter. Use a lux meter to monitor, maintaining 30000-50000 lux in the growing season and increasing to 50000-80000 lux during flowering to promote bud differentiation.
2.2 Temperature Gradient Control
Creating an environment with a day-night temperature difference of 8-10°C is more conducive to growth, keeping the daytime temperature at 25-30°C and reducing it to 18-20°C at night. For the winter period, use a double-layer insulation method: the inner layer with a transparent plastic bag (with ventilation holes) and the outer layer wrapped with non-woven fabric, which allows the plant to safely survive temperatures below 10°C.
Three, Water and Fertilizer Synergy Supply Strategy
3.1 Smart Irrigation System
Install a soil moisture sensor, set the matrix water content to automatically irrigate at 20-25%. Use immersive watering in the growing season, lasting 10 minutes each time; change to mist watering during dormancy, maintaining air humidity at 60-70%.
3.2 Nutritional Cycle Management
Apply a compound fertilizer with N-P-K=20-10-10 during the germination period, switch to a 10-20-20 formula during the budding period, and add organic seaweed fertilizer after flowering. Combine with foliar application of 0.2% potassium dihydrogen phosphate, cyclically every 20 days, which can increase the flower yield by 40%.
Through systematic environmental control, combined with precise water and fertilizer management, Huang Chan can achieve an ornamental effect of over 200 days of flowering per year. It is recommended to repot every spring, combining root pruning and updating the substrate, using a vitality agent to dip the roots can shorten the recovery period. Master these core techniques, and your Huang Chan will certainly become a model for neighbors to seek advice on care.
