Their thick, white roots are specially adapted to absorb moisture and dissolved nutrients. Because these tropical orchids usually grow high in the trees, rather than on the forest floor, they are accustomed to good air circulation and plenty of light. They prefer a 12-hour day, all year-round, and require a high intensity of light — about the same as midsummer conditions in temperate regions. Many people make the mistake of assuming that since orchids are native to tropical rainforests, they must be watered several times a week. Unfortunately, watering this frequently will kill the roots of any orchid in short order.
The general rule of thumb for orchids grown in the home is to water every 5 to 12 days, depending on the type of orchid, the temperature the plant is grown in, and the time of year. Unlike ferns, philodendrons, palms and Swedish ivy, orchids do not grow in soil. Potting an orchid in soil is actually one of the best ways to kill it. Most orchids in the wild are not rooted in the ground, but instead attach themselves by thick roots to the sides of trees and on branches. Clinging to the bark, the plants absorb water and nutrients from the air and rain and whatever drips down the tree. They are adapted to surviving when rain is scarce, hoarding water in thick leaves, stems and roots.
Fertilize orchids weekly or bi-weekly while they are producing new growth and decrease to monthly or bi-monthly intervals once they mature. Discontinue altogether once the plants go dormant. There are several types of growing media that can be used with orchid plants—redwood or fir bark, sphagnum peat moss, rocks, cork, charcoal, sand, potting soil, etc. A basic mix for growing orchids consists of coarse perlite, fir bark, and sphagnum moss. You can also add charcoal but this is optional. Generally, the grade of bark is dependent on the type of orchid grown. For instance, phalaenopsis orchids are usually grown in coarse bark, cattleyas in medium bark, and young orchid plants are best grown in fine bark.
When there are many, long roots over the edge of the pot, this plant has most likely been growing for several years since its last repotting. If your plant is not currently in bloom, you should repot now. Be sure to remove all dead roots that are usually dark-colored, soft and mushy. Sometimes they may be dry, with a fiber running through the middle of the root. Center the plant with all of its roots down in the pot and add moistened bark until the level of the bark is just below the bottom of the lower set of leaves. Wait a week before resuming your normal watering and fertilizing routine.

Orchids prefer high air humidity, but their roots will rot easily in wet compost. Water them about once a week, ideally using tepid rainwater. Water from above and tip out any water that collects in the saucer under the pot. Alternatively, plunge the container into a bucket of water and allow to drain thoroughly. Be sure to use an orchid food that is formulated for orchids and follow the instructions on the label. In general, most orchid fertilizers recommend usage once a month. Less frequent fertilizing may stunt growth and inhibit flowering; more frequent fertilizing may burn the roots and leaves and inhibit flowering. Most orchids require moist, well-draining conditions.

Orchids are usually grouped into two broad categories that characterize their growth habits. Monopodial orchids have a single, upright stem, with leaves arranged opposite each other along the stem. The flower stem appears from the base of the uppermost leaves. Orchids with this growth habit include the phalaenopsis and vandas. The more common growth habit is sympodial. These orchids grow horizontally, sending out new shoots from the old rhizome. Leaves and flower scapes form at the top of the new shoots. Many sympodial orchids form pseudobulbs, which are swollen shoots that store water and nutrients to help the plant survive periods of prolonged drought. Sympodial orchids include cattleya, cymbidium, oncidium and dendrobium.

Repot every two years regardless of whether the orchid has outgrown its pot, as older orchid compost breaks down, preventing air reaching the roots which leads to disease. Always use proprietary bark-based orchid compost, never a loam-based or standard multipurpose one as these will kill your orchid. Care of indoor orchid plants is easy once you learn how to grow them properly. These interesting flowers can be found in a range of colors and sizes depending on the variety. They make excellent accent plantings to nearly any home décor. Orchids require little care once all their basic needs are met such as light, temperature, and humidity. Orchids are different from other houseplants. Take note of that.
