Potted plants need to be fertilized, especially if in the same pot and soil for a long period of time. Many types of fertilizers are available and any may be used according to label directions. Select one which gives the best results for existing growing conditions. Do not fertilize dry plants as the roots may be burned. Water, then fertilize in a day or two. Resting house plants need no fertilizer.
Prepare to survive on your own for at least three days. Assemble a disaster supply kit. Be sure to include winter specific items including rock salt to melt ice on walkways, sand to improve traction, and snow shovels. Keep a stock of non-perishable food and extra drinking water.
Prepare for isolation in your home. Maintain several days supply of medicine, water, and food that needs no refrigeration. Have sufficient heating fuel, regular fuel sources may be cut off. Have emergency heating equipment and fuel (a gas fireplace or wood burning stove or fireplace) so you can keep at least one room in your home liveable. Be sure the room is well ventilated. If a thermostat controls your furnace and your electricity is cut off by a storm, you will need emergency heat.
