It's time to start thinking of spring. We're here to help you prepare for sprouts poking up, fragrant breezes, and warmer temperatures. Planting seeds indoors 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 plant seeds into the earth.

Plant Hardiness Zones Explained
The first thing to learn 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 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. 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 should even out as time passes.

Gardening in Your Growing Zone
Growing season starts early and ends late in this part of the country. The weather and climate make it easy to get and keep a beautiful garden going. A wide variety of veggies, plants, and flowers thrive in the Gulf region. You can even grow citrus trees for fresh fruit when you plant somewhere with good soil drainage. You'll have excellent results with peppers of all heat levels and colors, including jalapeños, bell peppers, and more. Cucumbers, zucchini, squash, and pumpkins, which are direct sow only, will flourish. Tomato plants will yield thriving leaves and fruit, as they're tropical in origin and are happiest in the heat.

In balmy Zones 9 and 10, you can begin planning and planting indoors in January if you’d like. Zone 8 generally has a slightly later recommendation for indoor starts. Cruciferous veggies and garden favorites, like peppers, do well when started inside your home. Greens like spinach, artichokes, and fragrant herbs, including parsley, basil, and oregano, also don't mind an early beginning.

You can sow spring flower seeds and watch them mature under the grow lights, too. In this part of the country, your garden might still be growing if there's no reason to put it to bed — especially if it's close to the house or in a greenhouse. In that case, tend it as usual. Whatever you choose to grow, transplant them after the last frost.

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

Your seeds might struggle to grow or get washed away, or rodents or insects 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 and primed to survive, although there are no guarantees in the long term.

Start Seeds Indoors
If you'd like more control over your seedlings' journey or you're eager to get growing, 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 sun. Keep your seeds warm with warming mats and grow lights, water them carefully with a mister 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
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, dig deeper than you think with your garden trowel and leave plenty of room around the stem. You don't want to damage the roots. Put the plant in the hole and ensure it's even with the surrounding soil.

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