Humidity

Orchid Care and Maintenance Tips : Temperatures for Orchids (Part II)

As I briefly mentioned in Part I of my Temperatures for Orchids series, a change in temperature should always coincide with a change in humidity.  For example, you’ll want to make sure there is sufficient humidity when increasing temperatures and vice-versa. 

You can keep things in check by using a simple hygo-thermometer.  A hygo-thermometer lets you check humidity and temperature levels at a glance.  I bought the Extech 445702 Hygro-Thermometer and Temperature Monitor years ago and now own three of them.  It makes monitoring the humidity and temperature environments of your orchids really easy.   The digital LCD display is large and easy to read.  The device is portable or can be mounted on the wall–near your orchids.

If you’d like to just monitor the temperature, you can’t go wrong with the waterproof pocket-sized thermometer.  The great thing about this little guy is that you can take fast, accurate temperature readings with just a push of a button.   It’s great if you have to have to monitor a few orchids in different locations.  At less than $20 each, they make great gifts.

These are my favorite devices for monitoring the temperature/humidity levels for my orchids.  Do you have any favorites you’d like to share?  Send me an email at carol (at) orchidcarelady (dot) com.  Hope to hear from you soon!

Cymbidium Orchid Care Instructions

Follow these simple cymbidium orchid care instructions to keep your cymbidium babies happy, healthy and blooming!

Cymbidium Orchid Care, Orchid Care, Cymbidium Orchids

Cymbidium orchids are prized for their long-lasting sprays of flowers, used especially as cut flowers or for corsages in the spring.

Light is important for growing cymbidiums. They need high light but cool temperatures. Leaves should be a medium to golden green in color, not dark green.

Temperatures are another critical factor in flowering cymbidiums. Cymbidiums requre day temperatures of 75 to 85 F (or more) and night temperatures between 50 to 60 F. (Day and nighttime temperatures can be 5 degrees lower during the winter.)

Water to provide a constant supply of moisture to cymbidiums. Water heavily during the growth season (spring and summer), keeping the potting material evenly moist. Reduce water when the pseudobulbs complete growing in late summer. (The pseudobulb is a storage organ derived from the part of a stem between two leaf nodes.)

Humidity should be kept at 40 to 60 percent. Keep air circulating to prevent orchid pests and diseases.

Fertilizer should be applied during the growth season (spring through late summer), high nitrogen fertilizer (such as 30-10-10) is used. In late summer, use a high-phosphorus, blossom-booster fertilizer (such as 10- 30-20), to help form bloom spikes.

Potting is usually done in the spring after flowering, usually every two years or when the potting medium decomposes. See pages 55-61 in Orchids Made Easy for clear step by step instructions and illustrations to show you how to repot an orchid.

Phalaenopsis Orchid Care Instructions

Phalaenopsis orchids are among the easiest growing orchids for beginners!  These beauties can flower throughout the year (peaking in the spring) and are incredibly easy to care for as they enjoy much of the same indoor conditions found in our homes.  Just look at these flowers bloom!

Phalaenopsis Orchid Care Instructions

Phalaenopsis Orchid Care Instructions : (You might also find my post on the anatomy of a phalaenopsis orchid helpful.)

Light They grow easily in a bright window, with little or no direct sunlight.

Temperature Phalaenopsis should be above 60 F at night, and range between 75 and 85 F or more during the day.

Water Because they have no major water-storage organs other than their leaves, they must never completely dry out. Phalaenopsis orchids should be thoroughly watered and not watered again until nearly dry.  Want to know how I water my orchids?  Check out my Orchid Care and Maintenance Tips : Watering Your Orchids post for more details on my drench and drain method.

Humidity The recommended humidity is between 50 and 80 percent.  You an adjust humidity levels in your home by setting the orchids on humidity trays or on gravel, partially filled with water, so that the pots never sit in water.

Fertilizer It is best to fertilize your phalaenopsis orchid on a regular schedule, especially if the weather is warm, when the plants are most often growing.  Twice-a-month applications of high-nitrogen fertilizer (such as 30-10-10) are appropriate where bark-based media are used. Otherwise, a balanced fertilizer is best. When flowering is desired, a high-phosphorus fertilizer (such as 10-30-20) can be applied to promote blooming.  You can also dilute the fertilizer into your orchid’s water, making it a regular part of your watering schedule.

Potting This is best done in the spring, immediately after flowering. Phalaenopsis orchids must be potted in a porous mix. Potting is usually done every one to three years. Mature plants can grow in the same container until the potting medium starts to decompose, usually in two years.

To repot, remove all the old medium from the roots, trim soft, rotted roots, and spread the remaining roots over a handful of medium in the bottom of a new pot. Fill the rest of the pot with medium, working it among the roots, so that the junction of the roots and the stem is at the top of the medium.
