Cattleya prefers a difference in daytime and nighttime temperature.1 They like bright but indirect light and will have medium green leaves when they are in the right spot.1
Allow to dry before watering, depending on media, plant size, growth rate, and environment, this could be anywhere from every day to every ten days.1 If in doubt let it go another day before watering.1
When the plant has six or more psudo bulbs it may be divided.1
Do not re-pot a cattleya until the pot looks like it will fall over. The cattleya should be divided having four canes per division.2
Cattleya is tender, so ensure you wait until all danger of frost has passed in your area before considering planting outside - as a guideline, the minimum temperature outside should be approximately 13°C / 55°F.These estimates for how long Cattleya takes to sprout, grow and harvest are from real observations from real gardeners, right around the world.

Cattleya will not bloom on old pseudobulbs, but they will provide strength for the plant.
