The Drought and What to Do About It

The eastern U.S. has had drought conditions for the past three years. Instead of getting our average of 40–42 inches of rain a year, many of us have averaged 25–30 inches. Some have missed the equivalent of a year’s worth of rain, and the end is not in sight. Most plants are stressed and are likely to be more so if water use restrictions become more severe.

Freezing winter weather can be especially tough on drought-stricken perennials and shrubs. If regulations permit, water these plants well once a week as long as the ground temperature is above 40 degrees. Once ground temperatures drop below 40 degrees, most plants go dormant and require less water. A six- to 10-inch layer of leaf or straw mulch will help protect roots during the winter. For best results, mulch in late November or early December, after field mice and voles have found homes elsewhere.

A long-term response is to plant drought-tolerant species such as echinacea, lavender, thyme, oregano, and sage. These plants do well in low-water situations and are excellent for border or landscape use.
