When temperatures are expected to plummet, take steps to protect your outdoor container plants.
Soil insulates plant roots, so the larger the container the safer the plant. But big containers are difficult to move to a garage or sheltered location, and temperature drops to the teens and 20’s can threaten plant roots and pottery.
Traditional solutions include surrounding the pots with hay bales or a “cage” of leaves. Here’s a new idea. Try wrapping several layers of bubble wrap around your large ceramic pots. This technique provides insulation and helps both pot and plant survive extended cold spells in great shape.
