We had an unexpected snowfall overnight and this morning, and while I’ve known for weeks I needed to do something with my plants before they ended up as frozen mush, snowfall was decidedly a surprise.
It was also better than the alternative at this time of year, a freeze, because while more tender plants will be tinged with air cold enough to produce snow, it’s also full of moisture which helps to protect leaf and petal surfaces, and plants under cover of a deck or tree aren’t as badly affected. A freeze is typically cold with a clear sky and low humidity, and any plant outdoors that has moisture in its leaves is pretty much done for.
Often annual plants are thriving in the autumn, into a second bloom after the heat of late summer is moderated by the cool dampness of early autumn. Many plants can be brought indoors and kept as houseplants through the winter, which saves you both time and money next spring when you can start with plants that are already growing.
You may have a variety of plant or a color of flower that is difficult to find, a plant that has an emotional tie to someone, or heirloom plants you’ve purchased or started from seed or cuttings. But you need to take precautions about what plants do well indoors, what might hitch a ride indoors with your plants, and what your pets might decide to do with all that lush greenness.
