|When is the proper time to bring in my tropical plants (Shefflera, ferns, palms, etc.) before it gets too cool? I've heard conflicting answers including 45 degrees and 50 degrees.|
|Tropicals are not very fond of cold temperatures even if it is not cold enough to frost. They vary in their tolerance to cool weather, but as a general rule when nighttime temperatures drop to about 50 degrees they should come in. Some may do fine when exposed to 45 for a brief time, but some will not. Remember that the change in light from outdoors to indoors is a dramatic one and plants do better if you condition them by gradually bringing them in to the lower light environment. |
You can accomplish this by moving them first to an intermediate light level for a couple of weeks and then indoors, or by bringing them in at night and then leaving them in for longer periods of the day over the course of a couple of weeks.
Good luck with your tropical plants!
