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

Plant Hardiness Zones Explained
The first thing you should know when planting spring flowers, vegetables, 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 plant hardiness zone map and learn when to plant seeds.

For example, you could transplant bell peppers outdoors in mid-March in Zone 10, but not until the end of May in Zone 4. You'll have good results with plants that have your zone number or less. In other words, a Zone 9 garden can support plants listed as Zones 1–9. The timeframe to direct sow outdoors in your garden is often around a month later than the indoor start date. Be sure to read your seed packet for details. If you start them later than recommended, it's not ideal, but it will likely 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 kale, broccoli, and cabbage. Greens like spinach, artichokes, and fragrant herbs, including oregano, basil, and parsley, 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.

Start Seeds Indoors
Grow your garden from seeds by starting them indoors. We've got all the seed starter supplies you'll need. For best results, you'll want grow lights or a warming mat to go with your seed tray or planter pots. If you're planting a larger garden, use seed trays — like the ones you see sprouts in at your Madison Heights Garden Center — to make it easy to stay organized and plant tiny soil plugs later. You can also use pots with potting soil and seed starter mix.

Measure your finger to use it as a ruler. In general, you'll plant 3–5 seeds, then press them into the soil to the depth you need with your finger. Mark where you planted the seeds with a toothpick or plant tag. That way, you'll know where your seeds should pop up. Otherwise, it'll be a surprise when the sprouts push out of the soil.

Sprouts
When your seeds have sprouted but aren't ready to go outside yet, you can still prepare them for outdoor life. These micro-seedlings are fragile — only an inch or so high, with the tiniest seedling leaf or two — but they're resilient. Seedlings don't get all this pampering in nature when they volunteer and grow wherever, so they can handle more than you think. However, don't go overboard, as your sprouts are still babies. You can even use an oscillating floor fan on low to mimic the wind and strengthen their stems.

Harden Your Seedlings
Harden your seedlings for best results later. On days above 45 degrees, take your pots or trays of seedlings outside to slowly warm in the shade for two hours, but bring them inside at night. Cloudy days are fine, but no harsh nighttime chills or direct sunlight yet. After a week or more of this, you can leave them out overnight if the temps stay warmer than 50 degrees. Cover your plants if they're in the ground and a late-season frost sneaks back in.

Transplant Young Plants Into Their New Homes
Carefully take your seedling out of the container. A good way to do this is to turn it upside-down or sideways and gently squeeze the plastic to break the seal. If your transplant grew in the garden, leave plenty of room around the stem and dig deeper than you think with your garden trowel. You don't want to damage the root ball. Put the plant in the hole and ensure it's even with the surrounding soil.

Protect Your Garden With Mulch
Finish off your garden with compost and mulch. Compost enriches the soil so your garden can grow even better. It may help foster stronger plants that bear more flowers and fruit. Mulch keeps your soil from drying out and controls weeds. Mulch and compost can be DIY creations, but you can also purchase them in-store. The next time you're looking for "mulch near me," stop by the Garden Center to get the perfect amount.
