You should fertilize your blooming plant once every two weeks with a balanced fertilizer at half the specified strength. A longer interval is best under cooler or lower-light conditions. Over-fertilization causes excessive foliage growth, side shoots or foliage burn. As a rule, under-fertilize a blooming plant to keep it hungry. This will allow the plant to bloom

is a great plant to grow indoors. They bloom best with bright, indirect sunlight from a north or east-facing window. They prefer a temperature between 55 and 60 degrees and can bloom without being planted in soil. You can simply wash the roots of any soil and submerge the roots into a large vase of water. This method is great for blooming indoors, and will keep your blooms around much longer. Keep the water temperature consistent

need to be kept in a warm location with as much light as possible. Early morning sun is ideal or full rays from the winter sun. During the spring and summer, diffused or filtered light is necessary. Grow only one plant per pot, and remove the side shoots (figure C) .

They should break right off.
Orchids (figure D)

figure D
grow easily in a bright window with little or no sun. They love humidity. Watering is essential because they have no watering storage organs other than their leaves--they must never dry out. Set your orchid on a tray of gravel, partially filled with water (figure E) .

This way the pot never sits in water.
