subject: Caring For Orchids In A Greenhouse Is A Rewarding Pursuit [print this page] Orchids are gorgeous flowering plants, many of which are tropical and some of which are epiphytes, or aerial plants. The aerial orchids cling to rocks or other plants and derive their moisture from the air and rain, so they need a humid climate in which to grow. Growing orchids in your greenhouse involves some extra attention, especially if you are in the wrong climate for them. Here are a few tips to keep in mind as you care for your hothouse orchids.
These orchids get the nutrients they need to thrive from the air and rain and from organic debris that accumulates on the supporting surface around them. To maximize their health, you can also add some potting mix. Many orchids bloom for days on end when they have had their share of potting mix and orchid fertilizer.
These orchids need a good watering at least two times a week, but they need extra humidity every day if they are to flourish. You will need to mist them lightly on a daily basis, or place them on top of a humidity tray. A humidity tray is easy to set up: just place some stones or pebbles on the bottom of a shallow tray. Add some water to the tray, but not enough to cover the stones because you do not want the orchid pot to sit in the water. Keep an eye on the tray and add more water whenever it gets too low.
Also make sure that the greenhouse doesn't get too hot for the plants. You will need some form of ventilation to keep the temperature in the right range for your orchids. A window or vent in the greenhouse will let fresh air in and keep things cool.
In the wild, it is natural for orchids to remain in darkness for some part of each day, a condition you will want to replicate in the greenhouse. To provide this necessary period of darkness, turn off the lights for several hours each night in and near the greenhouse.
Growing orchids in a greenhouse is an enjoyable and rewarding hobby. You will be able to enjoy the beautiful and fragrant blooms daily, and you can even cut a few to display in your home.
