The days are getting longer, the soil is warming up, and it’s finally time to get serious about your spring vegetable garden. But if you’ve ever wondered exactly what seeds to plant in April, the answer depends largely on your USDA hardiness zone.
Whether you’re starting seeds indoors, transplanting, or sowing directly in the garden, I am going to break it all down by region so you can make the most of your spring planting.
Let’s dig in—pun intended.
Understanding Planting Zones
Before planting, it’s essential to know your USDA Plant Hardiness Zone. These zones are based on the average annual minimum winter temperature and help gardeners determine what plants are most likely to thrive in their area.
If you’re not sure of your zone, you can find it by entering your ZIP code on the USDA Plant Hardiness Map.
