Unifoliate cattleyas are tough plants. They can take the heat in the summer and can handle low temperatures. I don't recommend temperatures below 50 degrees Fahrenheit for long though. They need fairly strong light. They can handle direct sunlight in the morning and evening but should be protected from direct sunlight in the middle of the day. They are stimulated to bloom by the length of the daylight hours. Many cattleyas have distinct blooming seasons. Many of them are fall or winter bloomers (decreasing daylight hours) with a few spring bloomers (increasing daylight hours) and very few summer bloomers. Most of mine bloom between November and February. They need plenty of water and fertilizer from late spring through the summer and much less of both during the fall and winter. They like for they're roots to dry out completely between waterings and they can tolerate dry spells of a week or more. Remember, in nature they grow attached to a tree limb with they're roots in the open air.
