It's time to start thinking of spring. We're here to help you prepare for warmer temperatures, fragrant breezes, and sprouts poking up out of the ground. Planting seeds indoors near a sunny window means you'll be ready to transplant young veggie plants and spring flowers when the frosts are through and the ground thaws. You might even want to directly plant organic seeds into the earth.

Plant Hardiness Zones Explained
The first thing you should know when planting spring flowers, veggies, and other seeds is your planting zone. Every location in the U.S. and its territories is sorted by climate. Find your zone on the USDA growing zone map and learn when to plant seeds.

For example, you could plant bell pepper seedlings outdoors in mid-March in Zone 10, but not until the end of May in Zone 4. For best results, choose plants in your zone number or less. In other words, a Zone 9 garden can support plants listed as Zones 1–9. You can plant seeds indoors roughly a month before you can plant them outside, or direct sow. Always read your seed packet for details. If you start them a little later than recommended, it's not ideal, but it will even out as time passes.

Gardening in Your Growing Zone
The Midwest is mostly Zones 6 and 7 throughout Indiana, Michigan, and Kentucky. You’ll find pockets of Zone 5 and stretches of Zone 4 in the Upper Peninsula. In Zones 5 and 6, the outdoor growing season doesn’t begin here until mid-March or even April, although you can plant some veggie seeds halfway through February. Warmer Zone 7 can start planting earlier, and Zone 4 much later on. Tomatoes, peppers, cucumbers, squash, and other classic garden crops will thrive in this region, and most of them can get an early jump on growing indoors before spring really moves in.

Also, check out cruciferous veggies and certain herbs if you're ready to get planting. This includes broccoli, cabbage, and kale. Greens like spinach, artichokes, and fragrant herbs, including basil, parsley, and oregano, also don't mind an early start. The main concern is waiting until the frost has passed for the season, so planting seeds outdoors as direct sow is later here compared to farther south.

Plant Seeds Outside With Direct Sow
Planting seeds into your garden soil, or using the direct sow method, is an alternative option. There's less tending and planning than growing indoors. If you like to go with the flow, follow the instructions on your seed pack and try it.

Your seeds might struggle to grow or get washed away, or rodents or bugs might eat the sprouts. But if you're really lucky, you might get a strong sprout from each place you sowed seeds, perfectly spaced and ready to grow all spring. The reality of your garden will usually be somewhere in between, and spreading out tiny sprouts throughout the soil isn't so bad. You know those sprouts are hardy, although there are no guarantees in the long term.

Start Seeds Indoors
If you're eager to get growing or would like more control in the care and feeding of seedlings, start your seeds indoors instead. In general, you can plant seeds indoors about a month before you can do it outside. Like direct sow, you push the seeds into the soil as directed on the seed packet, but that's where the similarities end.

You're responsible for giving them quality substitutes for sunlight and rain. Keep your seeds cozy with heat mats and grow lights, water them carefully with a spray bottle or watering can, then thin them as they germinate in groups of three. Give them a boost with a gently blowing fan as they lengthen into sprouts if you'd like. Harden them off to get them used to outdoor conditions, then transplant them into your garden when they're big enough.

Transplant Young Plants Into Their New Homes
Place your transplants in the ground, then water them well. Surround them with mulch, marking where the plant is with a tag so you can easily find it among the grass clippings, old leaves, or straw. If your yard is regularly visited by deer or rodents, consider putting up chicken wire or other protective measures so your plants and veggies are less likely to get eaten before they thrive.

Protect Your Garden With Mulch
Finish your planting by following it with mulch and compost. Compost enriches the soil so your garden can grow even better. It may help foster larger plants that bear more fruit and flowers. Mulch keeps your soil from drying out and controls weeds. Mulch and compost can be purchased in-store or created at home. The next time you're looking for "mulch near me," stop by the Garden Center to get the right amount.
