How Your Plants Respond to the Cold

Saturday was the coldest day this  Fall in Tucson.  63 degrees might be considered warm in other parts of the country this time of year, best cialis order but in Arizona, it’s downright cold.  And, when it’s cold for us that means it’s cold for your plants.  The only difference is that your plants have to remain outside all night while you get to spend time in your warm house.

When the weather cools off, your plants know that it’s time to prepare for the winter.  What does that mean?  It means that:

  1. Your plants will require less water.  Here’s a great resource for figuring out how much to water your plants and trees during the winter.  Watering by the Numbers

    This Lantana is Dormant and not Dead

  2. Unless your plants are winter blooming plants,  most will start going dormant and turning brown and losing their flowers.  This does not mean that they are dead.  This change helps them to survive the winter.  The roots remain alive and are kept warm by the dormant branches above ground.  So, don’t cut down your plants this time of year.  Wait until after the last winter freeze to protect your plants roots.
  3. Have frost cover sheets available to use to cover your frost tender plants so they don’t freeze and die if the weather gets very cold.  You can purchase these from any Home Depot or Lowe’s Home Improvement Store.  Landscape Plants for the Arizona Desert shows the Hardiness Level (the lowest temperature the plants can take before freezing) for common desert plants.  Make sure to remove the covers during the day.

Follow these easy steps to keep your landscape plants alive and well during the winter in Arizona.
