Local experts say this is the time when vegetable gardens should be in full production, with tomatoes, cucumbers, zucchini, beans, and peppers ripening daily. Many gardeners are now focused on regular harvesting, since picking produce often encourages more growth.
Flower gardens are also at their peak. Deadheading annuals, such as petunias and marigolds, helps extend color through late summer. Perennials like coneflowers and black-eyed Susans should be thriving, and many can be divided later this fall.
Gardeners are urged to keep up on watering, as August heat can stress plants and dry out soil quickly. Deep watering two to three times per week is recommended instead of light, daily sprinkling. Mulching around plants helps retain moisture and reduce weeds.
Pest pressure also tends to increase late in the season. Aphids, grasshoppers, and powdery mildew are common issues, so gardeners should check plants regularly and address problems early.
Looking ahead, now is the time to plant cool-weather crops for a fall harvest. Lettuce, spinach, radishes, and kale can still be sown for September and October picking, while garlic should be planned for planting later in the fall.
Extension agents note that while the growing season in the Black Hills is shorter than other parts of the state, timely care now will keep gardens productive until the first frost, which historically arrives in late September to early October.
