Growing Cattleya Orchids as House Plants – Practical Guide

Growing Cattleya Orchids as House Plants

Are you planning on growing cattleya orchids in your backyard or a greenhouse? Why not choose the Cattleya? They are very easy to grow as a house plant for beginners. However, if you decide on planting them on your window sill, you may find that very challenging.

What are Cattleya Orchids?

Cattleyas are beautiful orchids with large, attractive flowers which sometimes carry a fragrance. Their flowers vary in color and pattern and the size can measure as much as 8 inches across. There are numerous species. In wildlife, cattleyas grow high on trees in the forests. They have thick roots that attach the plants firmly to the tree. Being exposed to the elements, the roots can tolerate the long periods when there is no rain. Because they vary in size from small (suitable for window sills) to large; growing more than 4 ft. tall, you might want to choose carefully if you plan on growing them inside. They love light, so you wouldn’t want a plant that takes up all your window space, would you?

How to grow Cattleya and How to Take Orchid Care

1. Light

Cattleya orchids flourish in bright light. The condition of the leaves is an indication of whether or not your cattleya orchids plants are getting the right amount of water. Leaves that are firm and have an apple green colors mean that the plants are getting the right amount of light. Hard, yellow, or brown colored leaves suggest too much light, while limp, dark green leaves are an indication of an inadequate amount of light, which can also cause the plant not to flower.

If you keep your Cattleya on your patio in summer, they will thrive. If indoors, place them in an area near to windows on the eastern or western side. If they are outside, you must shield them from the hot, noonday sun.

2. Water

Cattleyas grow from an underground rhizome. During spring new bulbs appear. Cattleyas need lots of water during the growing season, but the bulbs should not be allowed to stay in the water.  As soon as the flowers begin to appear in the sheaths, reduce the water. Too much water in the sheaths will cause the young flowers to rot.

3. Blooming

CattleyasMost Cattleyas normally bloom once each year, some twice.  Flowers will stay between 1-3 weeks.  Once the first flower appears, the plants must be removed from the direct sun so that the bloom will last longer. The flower buds will not develop unless the plant gets direct sunlight and cool temperatures in the evening.

4. Temperatures

Cattleyas don’t need specific temperatures to grow. They thrive best in temperatures ranging from 55 degrees in the nights to 90 degrees throughout the day. During winter, the bloom cycle will start when evening temperatures are at 55 degrees or lower. They also need ample humidity and proper air circulation throughout the months of winter too.

5. Cattleya Orchids Fertilizer and Nutrients Feed

Fertilize your Cattleyas each week with weak fertilizer made for orchids.

6. Potting and Repotting Orchids Tips

Repotting of cattleyas can be stressful for the plant, so they will take a season to improve. Therefore, repotting should only be done when necessary.  Cattleyas flourish best in most orchid mixes including clay pellets, pine bark, charcoal, perlite, and any medium which drains well.  If you are repotting a Cattleya, ensure there is adequate space for the rhizome to produce a minimum of two bulbs.  The ideal repotting period is spring; that’s when the growing season begins.
