Tips for a Thriving Louisville Garden
Choosing the right plants is just the first step. Here are some tips for keeping your Louisville garden healthy and vibrant:
Soil Preparation and Amendments
Louisville soil tends to be clay-heavy, so consider adding compost or organic matter to improve drainage and soil fertility. Plants like daylilies and yarrow adapt well to various soil conditions, but others, like Dogwood and Redbud trees, may benefit from a bit of extra care with well-drained soil.
Regular Watering Routine
Louisville summers can get hot and dry, making a consistent watering routine essential for garden health. Consider a drip irrigation system to ensure even watering without water waste. Be mindful of plants like yarrow and Kentucky bluegrass that require less frequent watering, while others, like hostas and coral bells, need more consistent moisture.
