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 near a sunny window means you'll be ready to transplant young veggie plants and spring annuals when the frosts are through and the ground thaws. You might even want to directly plant seeds into the earth.

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

For example, you could plant bell pepper seedlings 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 9 garden can support plants listed as Zones 1–9. You can plant seeds indoors roughly a month before you can plant them outside, or direct sow. Read your seed packet for details. If you start them a little later than recommended, it's not ideal, but it will 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 flowers, vegetables, and plants 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 bell peppers, jalapeños, and more. Cucumbers, zucchini, squash, and pumpkins, which are direct sow only, will flourish. Tomato plants will yield thriving fruit and leaves, 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 when the threat of frost is gone for the season.

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 warming lights or a warming mat to go with your seed tray or plant pots. If you're planting a larger garden, use seed trays — like the ones you see sprouts in at your Pasadena 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. 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 certainly don't get all this pampering in nature when they volunteer and grow wherever they please, 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 off your seedlings once they're a few inches tall. This process of gradually introducing them to the outdoors makes 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
Place your transplants in the ground, then water them well. Surround them with mulch, marking where the plant is with a tag or stick so you can easily find it among the grass clippings, old leaves, or straw. Consider putting up chicken wire or other protective measures if deer or rodents visit your yard regularly, as your sprouts may otherwise become a snack.

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