Tall-growing orchids need a little extra support to stay upright, but the stakes they lean on are usually an eyesore. For ones that won't detract from the beauty of the blooms, purchase precut 16- to 18-gauge floral-stem wire from a crafts store. Bend into a 90-degree angle 4 inches from the top. Curve the top portion to form a U. Plant the stake next to the orchid, and hook the U around the stem.
