Dendrobiums like bright diffuse light, though most can be acclimated to full
sun. Your plant should have slightly lighter green leaves. If the leaves are
very dark green your plant is not getting enough light to bloom well.
WATER: Dendrobiums generally like to dry out between waterings.
Adjust your watering schedule to the time of year and the growing location
you've chosen. Keeping Dendrobiums indoors you should water them about once a
week. We recommend putting the plant in the sink and let the water run through
for about a minute. Let the plant drain in the sink before you put it back in
your decorative container. If you have your plants outside the watering
schedule depends on the season; in the hot summer plants need to be watered
every other day, in spring and fall two waterings a week should do, and in
winter reduce watering to once a week. Always water thoroughly and early enough
in the day that the plant can dry off by evening.
Dendrobiums are heavy feeders and require fertilizer about twice a month. We
recommend feeding with any general purpose water soluble fertilizer in place of
MEDIA: These plants are heavy rooted and do well in
most coarse orchid mixes. We recommend a blend of equal parts Aliflor and
charcoal, plus 10% coconut peat..
REPOTTING: It is good practice
to repot every two years. Do not over pot Dendrobiums, they like to stay tight
in the pot. Give them just enough room for two years growth.
DISEASE: Most plant diseases are caused by damp or stagnant
conditions. Proper watering practices and good air movement are the best
preventative measures you can take. To treat fungal diseases we recommend
Physan or RD-20, Aliette, and Manzate or other brand of these chemical groups.
Never use a copper base fungicide, as it will defoliate the plant. Against
insects like scale, mealy bugs and spider mites most good pesticides that are
labeled for plants will work on Dendrobiums. Powders and water based pesticides
tend to be better to use than oil base pesticides. Spraying should be done
after watering and during the cooler part of the day.
