Orchid Care - A Place to Grow

Those dazzling displays of flowers aren't magic. They're the result of months and months of growing in right environment. Orchids need time to build up the energy to create those magnificent blooms.

You'll get rewarded with big blooms if you give your orchids what they want during their growing season.

Successful growers create special "growing areas", where their plants get exactly what they need for healthy growth. They're reward is big, beatiful blooms.

What Do Orchids Want?

Unlike houseplants, who are generally happy with their surroundings year round, orchids expect varying conditions throughout the year.

In their natural habitat, most orchids experience hot, steamy, tropical weather during the summer ( their growing season), followed by cool, dry periods in the winter (their blooming season).

Temperatures can vary from the high 90's in the summer to the 40's and 50's during the winter. Rain showers are common almost every day in the summer, but they can be weeks apart in winter.

What growing conditions are your orchids looking for?

Lots of Light - Orchids need energy to bloom. The only place they get energy is from light.
Varying Temperatures - Most orchids need at least a 15-20 degree difference between day and night temperatures to trigger a bloom cycle. They simply won't bloom without it.
Adequate Humidity - Orchids can't tolerate dry air. They don't need a rain forest but they do require at least 20-30% realtive humidity. This can be a challenge during winter months.

Successful hobbyists create special "growing areas" to create these conditions for their plants.

Setting Up A Growing Area for Yuor Plants

Setting up a growing area for your plants isn't complicated.

Where can you find a place in your home that has good light, varying temperatures, and adequate humidity?

It all has to do with micro-climates.

"Micro-climates" are small areas that are hotter/colder, wetter/drier, or sunnier/shadier than the surrounding environment.

Your home has many micro-climates, especially around windows. These areas are generally brighter and hotter/colder than the rest of the room. You may not notice this - but from an orchid's perspective this can mean blooms or no blooms!

The best way to understand the micro-climates in your home is with our Hi/Lo Thermometer.

"When you stop guessing and start measuring you'll become a better grower!"

1. Light

Pick a window. Using the compass in your phone, determine what direction the window is facing. East and west windows have good light during summer months, but they don't have a lot of light during winter months. South windows are shady in the summer but get hot and sunny in winter.

Direct, intense sun (in any window) can burn leaves. Shear drapes or adjustable blinds are helpful if the window is in hot with lots of direct sun. Of course trees, awnings, etc. will also effect light levels.

2. Temperature

Temperatures in the micro-climate around windows can vary widely. A sunny window can reach 100 degrees or more - even in winter! That same window can drop to 60 degrees or lower at night. That's a 40 degree difference ... perfect for orchids!

Temperatures can be controlled even more by shutting off the heat vents at the window. Don't worry, your plants won't be too cold.

If shutting off the heat vents doesn't work, try installing heat deflectors over the vents. This will deflect the hot, dry air from the furnace away from your plants.

3. Humidity

Adequate humidity can be the biggest challenge in any growing area during the winter months. Two ways to increase humidity area -

1. Grouping plants together on humidity trays. Moving plants together naturally increases humidity. Adding humidity trays under your plants gives the humidity levels a real boost. As the water evaporates from the trays - humidity levels around your plants go up.

2. Turn down the thermostat a few degrees. Humidity levels are closely tied to air temperature. Air from your furnace is extremely dry. To promote higher humidity, try turning down the heat a few degrees, especially at night. Both you and your plants will be healthier!

Grower Tip: Misting plants. This might be great for people who think they always "need to do something", but it doesn't accomplish much. Unless you mist your plants every 20 or 30 minutes, you're not raising the humidity because the moisture from misting evaporates quickly. Misting is a poor solution - you need to consider other options.

Other Types of Growing Areas

Growing Under Plants Lights

With plant lights the sun shines every day so you can set up your growing area almost anywhere! Cool rooms or basements are best. The gentle heat from the grow lamps warms the plants during the day and the ambient room temperature cools them at night. This creates the temperature variance orchids need for blooming. (Basements are great for this because plants love the cool, damp air.)

With plant lights the sun shines everyday!

Spare bedroom or guest room

Spare bedrooms or guest rooms are excellent for setting up a growing area. Simply close off the heat and air conditioning in the room and close the door. The sun will gently warm the room during the day and your plants will love the cool nights.

Closing off heat vents eliminates the hot, dry air from the furnace and automatically raises humidty levels. Don't worry, your plants won't complain about being too cold.
