How to transition your garden for fall?

As summer wanes, gardeners are turning their thoughts to the fall planting season. Larry Stein, Ph.D., a horticulture specialist with the Texas A&M AgriLife Extension Service, offers timely advice for transitioning your garden to embrace the cooler months ahead, highlighting the importance of early planning to extend the gardening season.

Start planting cool-season crops

For those looking to enjoy fresh produce through the fall, Stein recommends starting with warm-seeded crops like sweet corn, winter squash, and southern peas immediately. “No one wants to garden when it is blazing hot,” Stein notes, “but planting now is crucial for a fall harvest.”

Cooler-season vegetables such as mustard, lettuce, arugula, broccoli, and turnips should be sown directly into well-prepared beds. Mid-October is ideal for planting root crops like carrots, beets, and leafy greens such as spinach, parsley, and cilantro, with some flexibility if using transplants.

Brighten your landscape with fall flowers

Flower plantings now can bring color to your landscape through the fall and into the spring in many regions of Texas. “Annuals planted early enough will start blooming by Thanksgiving and often last until Memorial Day,” Stein points out. Ideal candidates for early fall planting include petunias, calendulas, and pansies, though Stein advises waiting until the weather cools to plant these beauties. Biennials like poppies, larkspur, sweet peas, and bluebonnets can also be sown during this season.

Garden maintenance tips

Stein’s September garden guide includes several maintenance tasks to ensure your garden remains healthy and productive:

• Clear out spent plants and refresh the soil with compost and slow-release fertilizer.
• Ensure pecan trees and other large plants receive adequate water to support growth and fruit maturation.
• Revitalize heat-stressed plants such as geraniums and begonias by pruning, fertilizing, and watering.
• Continue to prune roses and other perennials to encourage a fall bloom.
• Regularly harvest vegetables like okra, peppers, and squash to stimulate continued production.
• Plant strawberries now for a spring harvest.

Addressing challenges

Despite improvements in drought conditions across Texas, water scarcity remains a significant challenge for many gardeners. Stein emphasizes the importance of adequate moisture, particularly for plants bearing fruit, to prevent stress and fruit drop. He also highlights the ongoing battle with pests such as white flies and spider mites, which can still thrive in fall conditions.

A light compost layer over seeds can help protect them during the still-hot early fall days, facilitating better germination and establishment of cool-season crops.

Stein wraps up with a nod to the perseverance required for successful fall gardening, quoting Jerry Rice: “Do today what others won’t, so that you can do tomorrow what others can’t.” This proactive approach, according to Stein, is key to a thriving fall garden.
