August provides gardeners with an important opportunity to maintain thriving landscapes while getting ready for fall planting and improvement projects. This month is a time to focus on regular care, prepare garden spaces, and support plants through the final weeks of the growing season.
Use August to combine ongoing garden maintenance with planning for future projects.
Vegetable gardens need close attention during late summer. Consistent watering is especially important during dry conditions, as vegetables require adequate moisture while growing and reaching harvest maturity.
Regular harvesting of crops such as tomatoes, cucumbers, and zucchini encourages plants to continue producing.
Gardeners should also remove damaged or overripe vegetables to help prevent problems with picnic beetles and other pests. Managing weeds before they develop seeds can reduce weed pressure in the following seasons.
Container plants and hanging baskets may require additional care during August. Removing faded flowers, cutting back stretched-out growth, and feeding plants with a balanced water-soluble fertilizer can help refresh their appearance and support additional blooms into early fall.
Trees and shrubs generally require minimal work during this period. Experts recommend avoiding major pruning or fertilizing in August, as encouraging new growth too late in the season can leave plants vulnerable to winter damage. These tasks are better completed in October or during spring.
Gardeners preparing for fall lawn seeding or new garden beds should begin site preparation now. Removing existing weeds, particularly deep-rooted perennial varieties, is essential for establishing healthier planting areas.
Stay on top of weeds, using whichever method you prefer, but if using a nonselective herbicide for active weeds be careful and use according to label directions, with enough time allowed before soil preparation begins.
August is also an ideal month to test garden soil. A soil test helps determine pH levels and available nutrients such as phosphorus and potassium, allowing gardeners to apply the correct amendments.
Proper soil preparation now can create stronger conditions for gardens and landscape plants in the seasons ahead.
