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

Plant Hardiness Zones Explained
The first thing you should know when planting veggies, spring flowers, and other seeds is your planting zone. Every location in the U.S. and its territories is sorted into blocks by climate. Find your zone on the USDA 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. For best results, choose plants in your zone number or less. In other words, a Zone 5 garden can support plants listed as Zones 1–5. The timeframe to direct sow outdoors in your garden is often around a month later than the indoor start date. Always read your seed packet for details. If you start seeds 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 certain herbs and cruciferous veggies if you're ready to get planting. This includes cabbage, broccoli, and kale. Greens like spinach, artichokes, and fragrant herbs, including parsley, basil, 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.

Start Seeds Indoors
Grow your garden from seeds by starting them indoors. We've got all the seed starter supplies you'll need. Make sure you have a warm and sunny spot that gets at least 12 hours of light. Then you have everything you need to try your hand at growing seeds. Early spring light isn't usually strong enough, so we recommend extra lighting to keep those seeds warm enough to germinate.

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
Prepare your seed sprouts for outdoor life while they're still indoors. 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 fan on low to mimic the wind and strengthen their stems.

Harden Your Seedlings
Harden off your seedlings once they're a few inches tall. This is a process of gradually introducing them to the outdoors, making them stronger in the long run. Hardening means you're less likely to lose your growing garden during a sudden cold snap.

Transplant Young Plants Into Their New Homes
Carefully take your seedling out of the container. Turn it sideways or upside-down 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 make sure it's even with the surrounding soil.

Protect Your Garden With Mulch
Finish your flower bed with mulch and compost. Mulch keeps your soil moist and controls weeds. Compost enriches the soil so your garden can grow even better. It may help foster larger plants that bear more fruit and flowers. Compost and mulch 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 right amount.
