1. Identifying Cattleya Orchids

Cattleya orchids are among the most diverse orchid species. They have robust, stocky stems and vibrant green leaves that lead to very large flowers with a diameter of approximately 15-20 cm. These flowers consist of 3-4 large, undulating petals surrounding the central column and spreading outward, exhibiting a wide range of colors.

2. Classifying Cattleya Orchids

Cattleya orchids come in a diverse range of varieties, exhibiting variations in both foliage and flower characteristics. Here’s how they can be classified:

Based on Origin

Natural Cattleyas:

These are Cattleya orchids found in the tropical rainforests of Rio De Janeiro, located in the southern part of Brazil. In nature, you can also find many naturally occurring hybrid Cattleya species, often used as fundamental breeding stock due to their robustness and prolific flowering. A common and typical forest Cattleya in Vietnam is the Han Mac Tu Cattleya.

Commercial Cattleyas:

Commercial Cattleyas are the result of extensive hybridization, resulting in various colors and patterns. When buying these orchids, you’ll have to wait for them to bloom as the flower appearance can’t be predicted when purchasing the seedlings. This category includes Cattleyas with large flowers as well as mini-Cattleyas with small pseudobulbs and clustered blooms.

Based on Growth Morphology and Flower Appearance

Regarding external characteristics, Cattleya orchids can be divided into two groups: single-leaved (Cattleya 1-leaved) and double-leaved (Cattleya 2-leaved).

Cattleya 1-leaved:

These Cattleyas have only one leaf and typically produce 1-2 flowers. The stems are usually 8-30cm tall, with thick, dark green leaves that measure around 20cm in length and 7cm in width. This group produces very large flowers, around 25cm in diameter, with a wide variety of colors. Currently, they are the most popular and valuable among Cattleya orchids. Examples include the white-lipped Cattleya, the red-tongued Cattleya, and the red Cattleya.

Cattleya 2-leaved:

These Cattleyas have two leaves and produce clusters of 5-7 flowers. Their stems are smaller and taller, approximately 60cm in height, with smaller, light green leaves measuring around 20cm. This group produces smaller flowers, with a diameter of 10-15cm, and their petals tend to be elongated. Currently, double-leaved Cattleyas mainly include mini-Cattleyas and antique Cattleya varieties. Examples include the orange mini-Cattleya and the Skinner’s Cattleya.

Understanding these classifications will help you choose the Cattleya orchid variety that suits your preferences and growing conditions.

3. Cattleya Orchid Planting Technique

Preparation:

• Pot Selection: You can use various types of pots for Cattleya orchids, including black plastic pots, wooden pots, or clay pots (with a diameter of 12-15cm). Ensure they have hanging hooks for Cattleya orchids. These orchids prefer humidity, so avoid using excessively large or well-ventilated pots.
• Growing Medium: The growing medium for Cattleya orchids should provide good root aeration, efficient water drainage, and high humidity retention. You can use materials like coconut fiber, pine bark, charcoal, fired clay pellets, or peanut shells. When planting in your garden, consider mixing coconut fiber with pine bark, fired clay pellets, and perlite.
• Orchid Variety: Choose healthy Cattleya orchid varieties with strong pseudobulbs, vibrant green leaves, and no signs of disease or unusual leaf coloration. Divide the orchid variety into segments, with 2-3 pseudobulbs per segment. Apply a thin layer of tree sealant to the cut area and let it dry in a cool place for 3-5 days. Soak the orchid segments in a sterilizing solution for 8-10 minutes, then let them drain. Subsequently, soak them in a fungicide solution for 5-10 minutes, and after about 3 days, proceed with planting.

Planting Cattleya Orchids:

1. Prepare a hanging hook before planting to provide support for the orchid.
2. Add the growing medium to the pot, starting with larger pieces at the bottom and gradually transitioning to smaller ones, leaving a gap of 2-3 cm from the pot’s rim.
3. Place the orchid segments near the edge of the pot so that the dormant eyes face inward toward the center of the pot. Secure the pseudobulbs to the hanging hook with ties, ensuring stability.
4. Ensure that the orchid’s base does not touch the surface of the growing medium. Water the medium thoroughly two days after planting.
5. Water the orchids regularly with a diluted vitamin B1 solution twice a week until the roots emerge and the orchid establishes itself. Afterward, switch to a slow-release orchid fertilizer.

Properly following these planting and care techniques will help your Cattleya orchids thrive and produce beautiful blooms.

4. Cattleya Orchid Care

Light

Cattleya orchids thrive in moderate light conditions, needing light exposure but not direct sunlight. To achieve this, provide about 50-60% shading with materials like green plastic shade cloth or a layer of thick black mesh. Space the pots apart to ensure each orchid receives sufficient light and good airflow.

Excess light can lead to symptoms like burnt or yellowing leaves, stunted growth, and rigidity. On the other hand, insufficient light results in dark green leaves and weak, leggy plants. Orchids grown in the right light conditions display pale green leaves with a hint of yellow or purple, producing large, colorful blooms.

Humidity

Cattleya orchids store water in their pseudobulbs and have an underground root system. They prefer humid conditions but require excellent drainage. Water the growing medium every 1-2 days, avoiding direct watering on the plant itself.

Ideal humidity for Cattleya orchids ranges from 40% to 70%. While they thrive in high humidity, standing water should be avoided.

Temperature

The ideal temperature for Cattleya orchids is around 21 degrees Celsius during the day and approximately 16 degrees Celsius at night. The climate in Dalat is suitable for growing Cattleya orchids, but they can also adapt to regions with higher temperature variations. In such places, orchids will still bloom but at a slower rate.

Fertilizing Routine

Use inorganic fertilizers with a 30-10-10 formula for young plants and a 20-20-20 formula for mature ones. Dilute the fertilizer at a rate of 1 teaspoon per 4 liters of water and apply it regularly, 1-2 times per week.

When the pseudobulbs begin to form flower buds, switch to fertilizers with a 10-20-20 or 6-30-30 formula, using the same dilution and frequency. Additionally, you can use slow-release pelletized orchid fertilizer for added convenience.

Inducing Flowering in Cattleya Orchids

To encourage Cattleya orchids to bloom, several conditions must be met: the plant must be mature, well-nourished, and in an appropriate environmental setting. There is always a trade-off between growth and reproduction in these plants, so any unfavorable growth conditions can trigger flowering.

Use a low-nitrogen fertilizer with a 6-30-30 formula to encourage firmness in the pseudobulbs. After two months, cease all fertilization and limit overwatering while increasing light exposure. These adjustments will prompt the orchids to produce flowers at the desired time. After the flowers have wilted, use a foliar nutrient spray to aid in the plant’s recovery.

Rest Period for Cattleya Orchids

Cattleya orchids are known for their dormant periods, which vary depending on climate and region, typically lasting one month per year.

During the rest period, orchids require reduced nutrients and water, with watering limited to once a day. Increase shading by 10% and adjust temperatures to around 10 degrees Celsius for cooler regions and 25 degrees Celsius for warmer areas.

5. Repotting and Propagating Cattleya Orchids

Cattleya orchids grow rapidly, so repotting them is essential, typically every 2 years. When you notice the pseudobulbs extending beyond the pot’s rim, it’s time to consider repotting.

Repotting Process: Soak the pot in a container of water with moss prevention solution for 30-60 minutes to loosen the roots. Use pruning shears to remove any rotten or excessively long roots, leaving about 10cm intact. Secure the orchid in the new pot, place it in a well-ventilated area until new roots develop, and then hang the pot on a rack. After repotting, spray a root stimulant (B1) once and refrain from watering for a week.

Propagation Method: Propagation for Cattleya orchids should be done approximately 4 months before their rest period. The parent plant is divided into segments, typically 3-4 segments (2-3 pseudobulbs per segment). Seal or dust the cut areas with fungicide and root stimulant. Each segment will produce a new pseudobulb that will mature enough to withstand the dormant period. When the rainy season arrives, plant each segment into individual new pots.

Conclusion

Cattleya orchids are easy to grow, with large and beautiful flowers available in a wide range of colors, making them a delight to cultivate. Caring for and growing Cattleya orchids is not difficult at all, as long as you understand their specific characteristics. Wishing you all vibrant Cattleya orchid pots!
