How to Care for the Simple Heart Orchid
The Simple Heart Orchid is favored by horticulture enthusiasts for its elegant flower shape and unique fragrance, but many beginners often encounter growth problems during maintenance. This article will systematically analyze the cultivation secrets of the Simple Heart Orchid, from environmental control to pest and disease prevention, to help you create a healthy and flourishing orchid landscape.
Three Elements of Environmental Control
Golden Temperature and Humidity Range
18-22℃ is the optimal temperature range for the growth of the Simple Heart Orchid, and the day-night temperature difference should be kept within 5℃. In summer, cooling can be achieved through misting, and in winter, a heating pad can be used to maintain a temperature above 5℃. It is recommended to keep the air humidity at 60-70%, with the help of a ventilation fan to circulate the air.
Light Cycle Management
Adopt a "morning light + scattered light" mode, receiving 2 hours of soft morning light daily before moving to a shaded area. In winter, this can be extended to 4 hours of full sunlight, and a lux meter can be used to monitor and maintain a light intensity of 5000-10000lux.
Substrate Proportion Optimization
How to Care for the Simple Heart Orchid
A recommended mixed substrate of volcanic rock + pine bark + perlite (3:5:2) is suggested, with a 5% addition of decomposed sheep manure every quarter. Use the "basin soaking method" for watering, soaking the entire substrate for 15 minutes after the surface turns white.
Double Core of Propagation and Maintenance
Division Propagation Timing
The best time for division is around the spring equinox, choosing pseudobulbs with 3 aerial roots. After cutting, apply charcoal powder and let it dry for 12 hours. Soaking in a rooting hormone containing indole butyric acid can increase the survival rate by 30%.
Precise Fertilization Plan
During the growing season (March-September), apply a special orchid fertilizer (N-P-K=20-20-20) every 15 days, combined with a seaweed extract foliar fertilizer once a month. During the budding stage, switch to a high phosphorus-potassium fertilizer (10-30-20), with the concentration controlled at 1500 times the liquid.
