Too Much Heat Can Damage Your Phalaenopsis Orchid
Monitoring temperature is an essential part of a successful orchid care program. Most growers are aware that they should not expose their orchids to temperatures that are too low, but do you know that overly high temperatures can also be bad for orchids? Orchids that are left in overly hot environments for long periods of time can be severely damaged, and their leaves may drop off.
Ideal Temperatures for Phalaenopsis Orchids
Phalaenopsis orchids can thrive under temperatures that do not exceed 90 degrees Fahrenheit, but they should not be continually exposed to this temperature. They need to be placed in cooler environments for a certain period of time in order to produce flowers. If you are living in a place that has warm climate, try to put your Phals in a place that has a temperature of about 60 degrees at night for at least two weeks. This will increase their chances of producing healthy blooms.
Preventing Damage from Heat and Sun in the Winter
Do not assume that temperatures in the winter are suitable for your orchids. Avoid leaving them in a place that has limited air circulation, very dry heat, or for that matter in a sunny window for a long period of time. If you leave your orchids near your heater in the winter, they can be damaged in as little as a few hours. Also, you have to be careful when you place your orchids in the windows during winter, because it can get very hot when the sun shines through the glass. Avoid placing the plants between the curtain and the window. The curtain can trap heat and make the area around the window very hot; so hot that damage may happen quickly.
