Xeriscape Gardening in the Winter

If you have worked hard to create your xeriscape garden over the summer months, you should know that the work is not done when the season is over. Even though plants don't grow, and may even become dormant during the winter months, below the ground, their roots are still growing for a good part of the year. It is important to prepare them for the cold months ahead and make sure that they come back strong and hardy in the spring.

Step 1 - Beef Up the Soil

Soil has a great quantity of natural minerals that are "locked up" and are not available to the plants. Using a Humate additive to your soil can unlock the minerals so they can feed your plants during the winter months, when they need it the most.

Step 2 - Fertilize

During the fall, while the weather is still warm, apply a fall fertilizer. Fall fertilizers are rich in potassium and phosphorus, which are both chemicals that aid plants in root growth over the winter months. Some fertilizers include Humate, so be sure to read the packaging to know if you will need to buy it separately.

Step 3 - Mulch

Give plants an extra layer of mulch in the fall to help protect from unnecessary heat loss.

Step 4 - Water

Yes, water. It is a common misconception that plant loss over the winter months is due to the cold temperatures, but usually it is due to lack of moisture. You should continue to water your plants throughout the fall, generally once every 2 to 3 weeks, depending on local precipitation. As long as the ground is not frozen, it is okay and a good idea to continue watering. Dormant plants need the water to prepare them for the chemical changes they will undergo to get them through the coldest winter months. In many places, the ground is too cold for watering in December and January, but into February may have warmed up enough to resume watering. Again, this depends on the amount of local precipitation.

Step 5 - Plant

If you live in a warmer climate, you may want to consider growing some "winter" crops in your xeriscape garden. These include vegetables that can withstand a light to moderate frost. It is best to check with your local extension office to find out what will do well over the winter months in your area. Make sure to find out what the moisture requirements of the your crops are, and plan their location according to water availability and drainage.

Step 6 - Transfer

If you grow herbs, many of them can be transferred to a pot successfully, and be enjoyed throughout the season. Although many herbs are very hardy and can survive the winter just fine, many also have shallow root systems and can be easily transplanted. If you use fresh herbs frequently, this is a great way to make sure you always have a fresh supply.
