How Do I Care for my Vanda Orchid?

How do I grow Vanda Orchids? Can I grow them outside on my covered porch?

Hi Melissa,

Vanda Orchids need very bright lightVery few houseplants should be placed in direct sun. High light refers only to bright indirect light since direct sun often burns the leaves of indoor houseplants. An area that is too hot and dry encourages Spider Mites and causes blooms to quickly fade. A northern exposure really doesn't provide enough light for high light plants. These plants need to be placed directly in front of an east-facing window, within 1-3 feet of a west-facing window, and within 5 ft. of a south facing window. A high light area has over 300 ft. candles of light. and warm temperatures to produce their beautiful colorful flowers. In warm climates they can be grown outside in partial shade. If you live in an area where the winters are cold, you can place your Vanda Orchid outside in the summer and bring it indoors to a bright sunny location the rest of the year.

Here are some care tips to help you grow a Vanda Orchid.

Light: Vanda Orchids love going outside in the summer as long as temperatures stay above 55F at night. Keep them in an area that gets partial shade. Move them inside as soon as the night temperatures cool down to the sunniest location in your home.

Water: Vanda Orchids like to be watered well when actively growing; but their roots need to dry out quickly. Cut back your water during cool days and when it is cloudy. Wait until the roots have dried before watering again.

Temperature: Vanda Orchids like temperatures between 60-70 F at night and no more than 95F during the day. These orchids grow faster in warmer temperatures and so need more water, fertilizerPlants need fertilizer only when they are actively growing. Slow growing plants in low light require very little plant food. Too much fertilizer is worse than not enough. Most plants prefer a water soluble plant food at 1/2 the recommended strength. Plants that are in bloom or dormant should not be fertilized. Houseplant food contains nitrogen (N), phosphorus (P), and potassium (K). A fertilizer containing these elements in equal proportion is considered a balanced plant food. Nitrogen helps in photosynthesis and encourages the growth of leaves and stems. Potassium and phosphorus also help in photosynthesis and aid in root and flower development. Most fertilizers have trace elements of other minerals that are lacking in the soil but are necessary for good plant growth. Fertilizers have a high salt content. If a plant is not producing new leaves and doesn’t absorb the fertilizer, salts build up in the soil. These salts can burn the roots, discolor the leaves, and cause new growth to be small., and higher humidity.

Soil: Plant your Vanda Orchid in pots with a coarse potting medium. Be sure there are drip holes in the bottom of the pot so the roots can dry out quickly.

Fertilize: Feed your Vanda Orchid  with a balanced plant food weekly during warm weather. You can also dilute your plant food to 1/4 the recommended strength and use it every time you water.

Applying a plant food high in phosphorus (10-30-20) every third time you feed your orchid help the plant flower more.
