Orchids are beautiful, exotic flowers commonly seen in supermarkets and florists in summer and fall when they bloom in a profusion of colours. Orchids grow on both bushy plants and tall stocks but always feature the same open, five-petaled blooms. The Doritaenopsis orchid is a moth orchid. It is slightly smaller than a Phalaenopsis, but it still sports an 8- to 10-inch stock with large blooms at the end. The Doritaenopsis orchid has very specific--and strict--care guidelines.
Place the orchid in an area where it will get bright light but not full sun. These orchids prefer light all day to maintain a temperature of 21.1 to 26.7 degrees Celsius. Situate the Doritaenopsis orchid in an east- or north-facing window. Watch the orchid's leaves to make sure it's getting enough light; bright green leaves mean it is, while dark green leaves mean it's not.
Monitor the growing foundation in your orchid's pot, and water it only when the soil is dry. Orchids don't like to have their feet wet, and they suffer in muddy conditions or standing water. Give your orchid an inch of water every five to 12 days.
Mix orchid-specific fertiliser with water, per the directions on the label, and fertilise the orchid once a month. Frequent fertilisation may burn the roots of the plant, while infrequent fertilisation keeps it from growing or blooming.
Divide orchids when they get too big for their pots or stop growing and blooming. Pull the orchid from its pot and growing foundation, and look for natural separations in the root and bulb system; these are spots where a new plant is already forming and are the best places to divide the existing plant.
