Supply water abundantly and often during growing season. Reduce water when the pseudobulbs stop growing in late summer. Keep barely moist during the winter.
Cool, about 50º nights and 70 to 80º days is ideal. Try to get 20 to 25º difference between night and day. Night temperatures between August and October should be 50º to 60º or lower to initiate flower spikes. Cymbidiums are very hardy and can go down in the 30’s or up to 90 or 100º occasionally.
FOOD AND LIGHT
Fertilize spring through late summer with high nitrogen fertilizer. In late summer, use a high-phosphorus, fertilizer in order to get good bloom spikes. Fertilize every week or two in summer and winter.
As much light as possible during growth in the summer. Yellowish foliage is okay. When in flower, shade heavily.
WHEN TO POT
Repot about every two years or when bark breaks down, after flowering, but repot only as necessary, as repotting retards flowering generally.
Fir bark; fir bark plus peat moss or sand; fir bark, peat moss, redwood fiber, leaf mold and some sand in large container.
