When to Plant Wisteria in Georgia?

When it comes to planting, timing is everything. Trying to plant anything at the wrong time of year may result in unhappy plants and frustrated gardeners. Fortunately, there are only a few things to consider when deciding when to add American wisteria (Wisteria frutenscens) to your Georgia garden. In many areas of the southern United States, wisteria can be planted successfully in either fall or spring.
  1. Wisteria Basics

    • American wisteria is a woody shrub that produces clusters of hanging flowers in mid to late spring. Hardy in U.S. Department of Agriculture plant hardiness zones 5 to 9, it grows prolifically once established and can wind its way around 10 feet of porch railing or pergola in one season. Although much less aggressive than its similar Asian species, Wisteria sinensis, it is considered an invasive species in some areas.

    Spring Planting

    • Because Georgia’s climate is such that the ground does not freeze in the winter, wisteria can be planted as soon as the danger of frost is past, typically around the third week in March. It’s important to plant early in the spring, when the wisteria plant is still dormant, to minimize shock to the plant and also to ensure the plant has time to establish healthy roots before warm weather increases its need for water and nutrients.

    Fall Planting

    • Fall is a good time to plant wisteria in Georgia and other regions with mild autumn temperatures. Fall planting gives root systems even more time to establish themselves before the next year’s growing season and gives the plant a head start toward flourishing in the spring. The key to fall planting is to have the plant in the ground at least one month before the first predicted frost, usually around the first week of November in Georgia. Ensure adequate water until the plant goes dormant for its winter nap.

    Additional Tips

    • If you happen to acquire a new wisteria plant in the middle of a hot Georgia summer, resist the temptation to find a spot to plant it right away. Keep the plant, in its nursery pot, in partial shade and water it daily, checking often to ensure the plant is not drooping or looking stressed. Clip off any blooms to avoid overtaxing the plant. Plant it as soon as the weather cools, usually by early October. It will still have plenty of time to stretch its roots and get settled in its new garden home.
