James Watson (1998):
"Imported plants often take a year or longer to establish before they will flower. In South Florida and other subtropical and tropical climates, sobralias are gaining popularity as garden plants. In temperate regions, sobralias can be grown indoors in conditions similar to those prescribed for cattleyas, although sobralias require watering more."
Hermann Pigors, Oak hill Gardens (1998):
"Sobralias are orchids without pseudobulbs, but with a heavy, fleshy root system. Keep them on the moist side, because many of them grow in seeps, and provide more shade than you would for cattleyas. Keep the plants in intermediate to warm temperatures (60 to 80 F)... the plants are fed once a week during the summer with a formula diluted at the rate of one teaspoon to one gallon of water... In winter, the sobralias are fertilized every three or four weeks with a balanced fertilizer (such as 20-20-20). Keep the plants pot-bound in containers that may appear proportionately small for the plant for the best growth and flowering. Occasionally, leaves will develop black tips, which may reflect too much or the wrong kind of fertilizer, mineral buildup in the mix or a decaying potting mix."
