It's time to start thinking of spring. We're here to help you prepare for warmer temperatures, and sprouts poking up, and fragrant breezes. Planting seeds indoors means you'll be ready to transplant spring flowers and young veggie plants 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 to know when planting vegetables, 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 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. The plants that'll thrive in your area are in your zone, and all the zones numbered less than that. In other words, a Zone 6 garden can support plants listed as Zones 1–6. The timeframe to direct sow outdoors in your garden is often around a month later than the indoor start date. Read your seed packet for details. If you start plants 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 oregano, basil, and parsley, 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.

Plant Seeds Outside With Direct Sow
Planting seeds into your garden soil, or using the direct sow method, is an alternative option. It doesn't give you as much organized planning in terms of reliability and spacing compared to indoor starts. However, if you like to go with the flow, follow the instructions on your seed package and try it out.

Your seeds might struggle to grow or get washed away, or insects or rodents 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 sown seeds will usually be somewhere in between, and spreading out tiny sprouts throughout the soil isn't so bad. You know those sprouts are primed to survive, although there are no guarantees.

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 rain and sunlight. Keep your seeds warm with warming 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
By now, your plants have three or four real 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 small plants into their new outdoor home. These large seedlings that are ready to be planted can also be called "transplants" or sometimes "starts." In cases where you direct sowed, you may still want to shuffle plants around for the best spacing and sun. That's also a transplant situation, as is repotting plants into larger pots.

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

Greet the Spring
Late winter into early spring is an exciting time in the world of gardening. Don't miss a minute of growing season. Prepare to fertilize your lawn, plan your garden and landscaping, and browse our garden center pages to find inspiration on what to plant when the weather warms. Shop for the seeds, fertilizer, and soil you need in the aisles of your Alpharetta Garden Center, online, or on our mobile app. Let's get growing together.
