If you’ve been searching “when to start gardening,” March is your signal to begin. In Louisville and across Kentuckiana, early spring is less about rushing warm-season planting and more about setting the foundation: healthier soil, smarter planting timing, and tools that make the season easier. 

At St. Matthews Feed & Seed, we help local gardeners get ahead with practical advice, region-friendly seed options, and quality garden essentials. Here’s your early spring game plan. 

Why Early Spring Prep Matters  

The gardeners who have the best-looking landscapes in late spring and summer usually do one thing differently: they prepare early. 
A few focused tasks in March can help you: 

• Improve plant health and root development 

• Reduce weed pressure before it ramps up 

• Avoid last-minute planting mistakes 

• Build a more resilient lawn before heat stress arrives
