TEMPERATURE – Most dendrobiums do well in an intermediate temperature zone. Day temps should be in the 70-90 degree range and night temps should be in the 55-62 degree range.
LIGHT – We recommend a fairly high light intensity for these orchids. Generally, cattleya light (2000-3000 foot-candles) is most suitable. If they are grown in the home, a brightly lit south or east exposure is best.
WATERING – Evergreen-type dendrobiums require heavy waterings in the growing season (spring and summer). As the new growth matures by fall, watering should be somewhat curtailed but not so much as to let the canes shrivel back.
FEEDING – Dendrobium orchids require a heavy feeding during their growth period, in general. But as with watering, feeding should be curtailed during the fall and the winter months.
REPOTTING – Repotting at the proper time is most important. For dendrobiums, spring is the best time to repot. Make sure that the new growth (with root action) has started before transplanting. Dendrobiums like to be somewhat root bound. Allow a very limited space for new growth. Use a coarse fir bark that allows perfect drainage.
