Here's my Missouri to do items for March.
Plant the following seeds and sets outdoors by early to mid-March: beets, carrots, collards, kohlrabi, lettuce, mustard greens, onions, potatoes, parsley, radishes, and spinach (following seed packet instructions).
Start seeds of summer vegetables like tomatoes, peppers, and eggplants indoors mid to late March (following seed packet instructions).
Hey I'm actually on time. Wait, potatoes? I did see seed potatoes in one grocery store but I'll have to make a bed from scratch in the sod outside the tunnel once the rain is done and things dry up a little. I'll have to hit the other grocery store that has more variety than just russet type. I like Yukon Gold.
If ever there was a Victory Garden veggie, potatoes has to be it. It's a staple after all.
March: Transplant the cool weather seedlings I started. Start another batch of them. Start some warm weather seedlings. Get some seed taters and make a tater bed.

Blooms March/April so yes, that's what I see around here.
I like the monthly To-Do Lists from Morning Chores.
March Gardening Tips and Tasks for Every Planting Zone and Region

Chores for me this month in SW Wisconsin:
Planting Zone Five
If you’re located in planting zone five you have a few more items on your to-do list than some of the previous zones.
It’s important to start seeds approximately six to eight weeks before they’re ready to be transplanted outdoors to give them time to prosper.
Plus, it’s important to plant cool-weather crops while the temperatures are still cooperating. Try to stay on task this month to keep from falling behind before the growing season truly starts:
Start seeds indoors and under grow lights for tomatoes, peppers, and eggplants
Prune your roses, trees, or shrubs for any winter damage they may have incurred
Plant potatoes, lettuce, carrots, peas, and radishes*
At the end of March, transplant early varieties of tomatoes outdoors**
*Sometimes our soil, even in a raised bed, is still frozen solid in March. So, planting times depend on warm enough soil more so than a date on the calendar. Invest $10 in a good soil thermometer. Well worth having as a reliable garden tool!
**NOPE! My last frost date isn’t until MAY 15th! My tomatoes go in at the end of MAY. The end of March is WAY too cold for them. If you’re going to plant that early, you’ll need to keep an eagle-eye on the temps and use protection for them from the git-go up here. I mean, it CAN be done, sort-of, maybe, kinda - but I’m not messing with all of that!
OK - Maybe Morning Chores needs to have more coffee before they make these broad lists of what happens when in the garden, LOL!
