Consistent watering is crucial for Ohio gardens, especially during the warm season. Aim for 1 to 2 inches (2.5 to 5 cm) of water per week, either from rainfall or irrigation.

Apply a 2- to 3-inch (5- to 7.6-cm) layer of organic mulch around plants to retain moisture, suppress weeds, and regulate soil temperature.
