In many parts of the world, October is the beginning of Fall. This is the time of year when the temperatures start to get lower and the long hot days of summer are coming to an end. This month I will be discussing the effects of temperatures on your orchids.
Temperatures play an important role in growing orchids.
Like most plants, orchids have their limits as to how hot or how cold they want to be. Each genera and each species have their own unique preferred temperature range. You need to learn what the proper temperature range is that your orchid prefers to keep it happy and healthy. Also, most orchids grow best when there is a difference in the temperature between day and night. The minimum length of the cool down period is usually two to three weeks in the fall.
