The Cultivation Methods and Precautions for Cattleyaorchid
As the "duchess" of the orchid family, Cattleya orchid captivates numerous orchid enthusiasts with its dignified and luxurious flower posture. However, many beginners often encounter problems such as difficulty in blooming and excessive yellow leaves during the maintenance process. Today, let's talk about the fundamental logic for Cattleya orchids to bloom healthily, and crack the maintenance problems through five key care dimensions.
One, Water Management Determines the Basic Survival
The Golden Rule of Seasonal Watering
In the growing period (March-September), keep the soil moist but not waterlogged, and spray in the morning and evening in high summer temperatures to supplement the humidity in the air. In the winter dormancy period, adopt the "dry-wet" method, and the water temperature needs to be the same as the room temperature to avoid root spasm caused by cold water irrigation.
The Hidden Skills of Water Quality Selection
It is recommended to use rainwater or tap water that has been standing for 3 days, and 1% white vinegar can be added regularly to adjust the pH value. Watering in winter is recommended to be done in the sunny and warm noon to avoid frost damage caused by low night temperatures.
Two, Substrate Proportion Affects Root Development
It is recommended to use the "3+2" formula: 3 parts of pine bark + 2 parts of sphagnum moss, mixed with a small amount of charcoal granules and volcanic stones. When potting every year, keep 1/3 of the protective soil, and the new soil needs to be disinfected with carbendazim solution 1 week in advance.
Three, Light Control Is Related to Bloom Quality
Daily shading techniques
Use 50% shade net in spring and autumn, and upgrade to 70% in summer. From September, gradually increase direct sunlight, with full sunlight in the morning and still shading in the afternoon. Judge by the leaf color: dark green indicates insufficient light, and yellow-green requires more shading.
Four, Nutritional Supply Focuses on Scientific Proportioning
Use a balanced fertilizer of 15-15-15 during the growing period, diluted 2000 times every half month for root irrigation. Change to a high-phosphorus fertilizer of 10-30-20 during the bud formation period, combined with foliar application of potassium dihydrogen phosphate. During the winter fertilizer pause, 5-8 slow-release fertilizers can be buried as a base fertilizer.
Five, Environmental Optimization Prevents Disease Occurrence
Maintaining a day-night temperature difference of 8-10°C can effectively promote flowering. For balcony maintenance, it is recommended to open the windows for ventilation at night. Use garlic water or tobacco water every quarter to prevent scale insects, and immediately wipe the leaf back with a wet wipe if red spider mites are found.
Cultivating Cattleya orchids is like nurturing a work of art, with every detail worthy of careful attention. Remember the eight-character slogan "Spring moist, summer shade, autumn light, winter control," combined with scientific substrate management and nutritional plans, and believe that next Spring Festival, your orchid will surely bloom with a dazzling and magnificent flower posture.
