By mid-August, gardening guidance focused on optimizing late-summer harvests and extending the growing season. For tomatoes, experts recommended “topping” indeterminate varieties and removing suckers or late-season flower clusters to redirect energy toward ripening fruit. To improve aroma and prevent fungal growth, gardeners were advised to water in the morning, directing moisture at the soil rather than the leaves. Moisture levels should be monitored by checking the soil at a depth of three to five centimeters.

To maximize yield and prevent fruit from bursting, tomatoes can be harvested once they begin changing color from green to yellow, orange, or light red. Because tomatoes continue to ripen after being picked, allowing them to finish ripening in a paper bag can relieve the plant. The Bayerische Gartenakademie notes that the ripening process can be accelerated using ethylene, such as by placing fruit near a ripe apple or banana.

Other seasonal maintenance includes pruning lavender after flowering and planting quick-growing crops like radishes, arugula, and spinach for autumn harvests. To utilize the end of the tomato season, home preservation methods such as drying tomatoes in an oven or making additive-free ketchup are recommended. Additionally, for pepper cultivation, steaming peppers in a closed container immediately after roasting can make them easier to peel.
