It's time to start thinking of spring. We're here to help you prepare for fragrant breezes, warmer temperatures, and sprouts poking up out of the ground. Planting seeds indoors with grow lights means you'll be ready to transplant young veggie plants and spring annuals 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 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 planting 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 6 garden can support plants listed as Zones 1–6. 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 seeds later than recommended, it's not ideal, but it should even out as time passes.

Gardening in Your Growing Zone
The Mid-South is in Zones 7–9, with coastal regions being warmest and the zone number decreasing to an 8, then a 7 as you go up in elevation to the foothills of the Georgia mountains. Just check your planting zone, then consult the seed packet for the most accurate instructions for each plant. If you know you're in a micro-climate near a lake, mountain, or valley, zoom in on the USDA planting map for exact details down to street level.

In balmy Zone 9 on the coast, you can begin planning and planting indoors in January if you'd like. Zones 8 and 7 generally have a slightly later recommendation for indoor starts. Cruciferous veggies and garden favorites, like cucumbers, peppers, and tomatoes, all do well when started inside your home. Greens like spinach, artichokes, and fragrant herbs, including basil, parsley, and oregano, also don't mind an early beginning. You can sow flower seeds and watch them mature under the grow lights, too. Whatever you choose to grow, tend them carefully and transplant them when the threat of frost is gone for the season.

Start Seeds Indoors
You can save money and gain the satisfaction of growing 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 and a spray bottle of water, good soil, and patience. 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. 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 inch-tall micro-seedlings are fragile but resilient. Seedlings don't get all this pampering in nature, 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 that are warmer than 45–50 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 above 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
By now, your plants have 3 or 4 true leaves — they'll look different from the miniature seedling leaves. When you're not expecting soaking rain, and the ground is warm, look into transplanting your big sprouts into their new outdoor home. "Transplant" means that you put these small plants straight into the garden soil or into pots. In cases where you direct sowed, you may still want to shuffle plants around for the best sun and spacing. That's also a transplant situation, as is repotting plants into larger pots.

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