Garden Supplies for Cincinnati

For container gardening in Cincinnati, always use a high-quality potting mix—never garden soil. Our premium potting mixes are specifically formulated for containers with excellent drainage and moisture retention, which is crucial during our humid summers. These mixes contain peat moss, perlite, and compost that stay light and fluffy, allowing roots to breathe while holding enough water for plants between waterings. For vegetables in containers, choose a potting mix enriched with slow-release fertilizer. For succulents and cacti, we offer specialized cactus mixes with extra drainage.

For landscape beds in Northern Kentucky, plan for 2-3 inches of mulch coverage. To calculate how much you need, multiply the bed length times width (in feet) to get square footage. One cubic yard of mulch covers approximately 100 square feet at 3 inches deep. For example, a 10-foot by 20-foot bed (200 square feet) needs about 2 cubic yards. We recommend hardwood mulch for most landscape applications—it breaks down slowly, adding organic matter to Cincinnati’s clay soil while suppressing weeds and conserving moisture.

For productive vegetable gardens in Cincinnati, we recommend a balanced approach combining slow-release granular fertilizer at planting time with regular liquid feeding during the growing season. Before planting, work our vegetable garden fertilizer (typically 10-10-10 or similar) into the soil. Once plants are established and actively growing, feed every 2-3 weeks with water-soluble fertilizer to support continuous production. Tomatoes, peppers, and heavy feeders benefit from extra calcium (prevents blossom end rot) and may need side-dressing with compost mid-season. Organic gardeners can use our composted manure, fish emulsion, and kelp-based fertilizers. Our staff can recommend specific products based on what you’re growing and your soil conditions.
