How to Care for Big Flowered Cattleya Orchid
Every time I see the graceful Big Flowered Cattleya Orchids at the flower market, I can't help but bring one home to care for. However, it doesn't take long before the leaves start to turn yellow and the flower buds fall off. In fact, this queen of orchids is not difficult to care for; mastering five key elements can make it bloom all year round.
Four Basic Care Steps
Light Control Is Important
In spring and winter, it is recommended to place it near a south-facing window, ensuring 5 hours of direct sunlight daily. In summer, use a double-layer sunshade net to filter strong light and pair it with a thermometer and hygrometer to monitor environmental changes in real-time. Special weather conditions may require the use of plant growth lights to maintain the light cycle.
Substrate Formula Should Be Scientific
Recommended golden ratio: pine bark (40%) + sphagnum moss (30%) + volcanic rock (20%) + charcoal (10%). When repotting every year, retain 1/3 of the old substrate and add newly prepared planting material to better help the roots adapt. Choose breathable clay pots or root control pots for potting.
Watering Rhythm Depends on the State
Judge by observing the pseudobulbs: pause watering when they are plump, and soak the pot immediately when wrinkles appear. Spray twice a day in summer, morning and evening, avoiding the open flowers. During the blooming period, use the saucer watering method, keeping the substrate slightly moist.
Nutrition Supplement in Stages
In the growing season (March-September), use 20-20-20 balanced fertilizer, combined with a monthly application of kelp extract. During the bud formation stage, switch to high-phosphorus and potassium fertilizer, and stop fertilizing during the winter dormancy period. After fertilizing, remember to rinse the leaf heart with clean water to prevent fertilizer damage.
Advanced Management Techniques
Best Time for Division Propagation
The best time for division is around Qingming Festival, choosing a healthy mother plant with 3 or more pseudobulbs. Apply cinnamon powder to the cut surface for disinfection, then let it dry for 12 hours before potting. Keep the newly divided plants shaded by 70% for the first two weeks, then transfer to normal management after new buds emerge.
Three Strategies for Disease Prevention
Regularly wipe the leaves with garlic extract to prevent (T-J) disease, and spray Bordeaux mixture before the rainy season to establish a protective layer. Isolate any plants with leaf spot disease immediately, cut off the diseased leaves, and apply Daktarin to the wound. Maintaining good ventilation in the environment is the key to the key.
Caring for Big Flowered Cattleya Orchids is like raising a VIP, requiring both meticulous attention and knowing when to let go. When you master the balance of light, water, and nutrition, this elegant flower will reward your efforts with a bloom period of up to three months.
