Here's a last minute checklist for your home and garden if the TV weather people (or panicky bloggers) tell you tomorrow's low will be in the mid-20's:
• If it hasn't rained, water plants thoroughly, especially container plants.
• If possible, move sensitive container plants next to a south or west facing wall.
• Cover citrus and other sensitive plants with burlap, row cover fabric or sheets (be sure to keep the sheets dry). Tent plastic sheets over the plants; don't let plastic touch plant leaves. A light bulb placed in such a plant can offer a few degrees of protection. For best protection, sheets should reach all the way to the ground around citrus trees and other freeze-susceptible plants.
• If using an anti-transpirant polymer coating material such as Wilt-Pruf or Cloud Cover, apply at the warmest time of the day, or at least six hours before an expected frost. Read and follow all label directions. If using these products, thoroughly water the plant before applying.
• Disconnect hoses and drip lines, removing end caps. Lay out straight.
• To prevent broken grass blades, don't walk on a frozen lawn.
• Remove the lowest sprinkler head to drain.
|Protect exposed pipes around wells and pumps|
• Cover unprotected faucets and pipes, including any spa or pool equipment.
• To prevent frozen attic pipes, let lukewarm water trickle out of the indoor faucet farthest from the inlet. Also, let faucets with pipes running along an outer, north facing wall trickle during the night.
• Open cabinet doors to get more heat to the pipes. Close the garage door if water pipes pass through the garage.
• Setting your thermostat nightly at 55 can add needed heat to the attic pipes.
• If leaving the house for a vacation during an expected freeze, turn off the water to the house, and open up the faucet farthest from the inlet. Be sure to turn off your water heater.
• To prevent cracking tile, run your pool and spa equipment during the freezing hours.
• Don't forget about your pets during a prolonged freeze. Bring them indoors at night. Move or replace their drinking water. Break up any frozen water in bird baths.
• Cover the worm bin, too!
