Vegetable and Herb Seeds to Sow in Michigan in April

We made it.

For most of us in Michigan, winter is finally over and we can solidly set our sights on the spring and summer garden. While some of us in the coldest zones may still have a snowbank or two lining the driveway or covering the garden, there are still seeds to be sown.

Here’s your zone-by-zone list of which seeds you can sow in April in Michigan, with a look forward so you’ll know what to have on hand for next month’s sowing.

Note: these are the dates for sowing seeds indoors or in a greenhouse. Plant most seedlings outdoors after your last frost date, but be sure to keep an eye on the weather, because we all know how unpredictable Michigan weather can be! If snow or frost is in the forecast, put your planting off for a day or two. Also be sure to start hardening your seedlings off a couple of weeks before you plant them out in the garden.

I hope this list is helpful for you, and I hope you’re as excited as I am to get my garden going. If you don’t have space indoors, many of these herbs and veggies can be sown directly into the garden after your soil has warmed and danger of frost has passed. Basil, corn, cucumbers, melons, lettuce, kale, kohlrabi, squash — all of them can be sown right into your garden soil and it works fine, though those of us who have shorter growing seasons may have to get creative with season extenders if we’re direct-sowing.

Happy gardening! If you have any questions, feel free to drop them in the comments and I’ll do my best to answer. Thanks for reading!
