Feeding

During the growth period orchids should be fed every week using a 30-10-10 NPK formula fertilizer for Cattleyas, Dendrobium, Epidendrum, Encyclia, Laelias, Sophronitis or a 10-10-10 NPK formula fertilizer for Vandaceous and Oncidioides in general.

During the maturation period (the three months just before blooming) use a 10-30-20 NPK formula fertilizer. The formula numbers indicate the fertilizer's proportions of three indispensable elements: nitrogen (N), phosphorus (P) and potassium (K). The label of the fertilizer container will show the formula of nutrients.

After blooming orchids enter their dormant period and no fertilizer should be applied until the beginning of the next growth period.
