Don’t put away your gardening tools just yet! Once the weather moderates, there’s still plenty of time to plant. In fact, fall actually is an ideal time for adding new perennials and shrubs to your garden to add beauty, privacy, and pollinator-friendly plants.  

In the Southeast, the toughest growing season for plants is summer. “Fall planting is ideal in warm to hot climates because it provides the longest window of good growth conditions before challenging weather sets in,” says Stacey Hirvela, horticulturalist with Proven Winners ColorChoice Shrubs. “Fall planting gives the plant a good 8 months or so to get established and develop a good root system before summer’s heat can stress the plant.”

Plants also tend to be less stressed during transplant at this time. “The weather is cooler, and rainfall tends to increase, providing a natural water source,” says Mary Woolman, woody ornamental and edible product manager at Star Roses and Plants. “Also, most plants will be preparing for dormancy by rooting, rather than pushing new growth.”

The only caveat is that you may not want to plant broadleaf evergreens, such as rhododendrons and magnolias, too late in the season. “It’s okay to plant these at the beginning of fall, but I would not recommend planting them after about mid-autumn,” says Hirvela. “Broadleaf evergreens are especially susceptible to drying out over winter, even in mild areas.”

Most importantly, don’t forget to water your fall plantings. Plants still need watered regularly through fall and even throughout the winter if the weather is unusually dry, says Hirvela.
