General Care for Orchids Grown Semi-Hydroponically

 

TEMPERATURE

A home environment with general room temperature works well for most orchids.  If you are comfortable in your home, chances are your orchid is too.  Many orchids prefer a change in temperature of about 10 degrees for optimum growth and flowering.  Our orchids are raised at temperatures of 75-85 degrees during the day and 55-60 degrees at night.

 

LIGHT REQUIREMENTS

Most orchids require a bright, shaded area of your home.  Direct sunlight may cause plants to burn, and too little light may prevent flowering.  Leaf color is a good indicator of light conditions.  Leaves should be bright green and healthy.  Leaves that are dark green may mean the plant is receiving too little light, where yellowing indicates too much light.

 

WATERING/FEEDING

The Orchid House recommends using the Michigan State University formulated orchid fertilizer with every watering.  We have had great success with mixing a ratio of 1/4 Teaspoon MSU fertilizer per gallon of water, all the time.

When watering, try to get the entire surface area wet.  The potting medium will absorb this and distribute to the plant’s roots.  When the reservior is empty, usually every 5 – 10 days, refill the container with your fertilized water mixture.  Generally, watering should occur more frequently during summer months or in dry conditions.

Occasionally, you might notice a buildup of salts on the potting medium.  One way to discourage this is to flush the plant during watering.  Using unfertilized water, fill the pot completely and drain.  Then water as usual with the fertilized mixture.

 

REPOTTING

With our semi-hydroponic growing method, the ceramic media will not decompose over time, and repotting is only necessary when the plant outgrows the container.  At that time, gently remove the plant from the existing pot and place into the larger container, then fill around the edges with more potting media.  The plant is not subjected to the shock of traditional repotting methods, and this can be done at any time.* These are general guidelines and not meant to cover specifics across the many orchid genres.
