To ensure the successful cultivation and flowering of this magnificent Cattleya hybrid, it is essential to provide the optimal growing conditions. Light plays a crucial role, whether you choose to grow it in a greenhouse or in the comfort of your home. Bright light, avoiding direct sun during midday, is ideal. Position the plant near an east, shaded south, or west window at home, while in a greenhouse, aim for 50 to 70 percent full sun, equivalent to 3,000 to 5,000 foot-candles. The leaves should display a medium green color, and the pseudobulbs should grow erect, requiring no staking.

Maintaining appropriate temperatures is key to the health of your Cattleya hybrid. Night temperatures between 55 to 60°F (13 to 15.5°C) and daytime temperatures ranging from 70 to 85°F (21 to 29.5°C) are recommended. For seedlings, slightly higher night temperatures are preferable. It is advisable to maintain a 15- to 20-degree differential between day and night temperatures, especially for mature plants. While higher daytime temperatures up to 95°F (35°C) can be tolerated, it is crucial to increase humidity, air circulation, and shading accordingly.

Watering is a critical aspect of caring for your Cattleya hybrid. It is recommended to provide water both in the pot and as humidity in the air. The frequency of watering in the container depends on several factors such as pot size, vessel type, temperature, and light conditions. Mature Cattleyas should be allowed to thoroughly dry out before watering again, while seedlings require more consistent moisture. To determine if your plant needs watering, compare the weight of a dry pot of similar size and mix. A light pot indicates dryness, while a heavy pot signifies moisture. When in doubt, it's best to wait a day or two before watering. Avoid using water below 50°F (10°C) or water softened with salts as they may harm the plants.

Maintaining an optimal humidity level of 50 to 80 percent is essential for the well-being of your Cattleya hybrid. In a home setting, you can achieve this by placing the plants on trays of gravel partially filled with water to prevent the plants from sitting in the water. Adequate air circulation is crucial to prevent fungal or bacterial diseases, particularly in high humidity or cool temperature conditions. In a greenhouse, using a humidifier is the most effective way to increase humidity, while evaporative cooling can simultaneously raise humidity and cool the air.

Regular fertilization is vital for promoting the growth and blooming of your Cattleya hybrid. When using fir bark as a potting medium, a high-nitrogen formulation such as 30-10-10 or a similar proportion is recommended. Alternatively, a balanced fertilizer can be used. During active growth periods, fertilize at least every two weeks, while during resting periods, once a month is sufficient. You can also apply diluted fertilizer with every watering, at one-quarter the recommended strength. It is crucial to flush the pot thoroughly with clear water every month to prevent the accumulation of fertilizer salts.

Potting becomes necessary when the rhizome of the plant starts to protrude over the edge of the pot or when the potting medium breaks down and drains poorly, typically after two to three years. The best time to repot is just before new roots sprout from the rhizome, after flowering, or in the spring. Mature Cattleyas generally require coarser potting material compared to seedlings. If a plant is not yet mature and has fewer than six pseudobulbs, it is recommended to place it in a larger pot instead of dividing it. When dividing a plant, ensure that each division has three to five pseudobulbs. Select a pot that allows for approximately two years of growth without overcrowding. Place potting mix against one side of the pot and remove any dead roots. Spread the firm, live roots over the pile, with the cut rhizome against the side of the pot. Fill the pot with medium, gently working it around the roots. Pack the medium firmly and stake if necessary. Keep the plant in a humid, shaded environment and avoid wetting the roots until new root growth is observed.
