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 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 sow 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 into blocks by climate. Find your zone on the USDA planting 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. 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 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. Be sure to 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 climate and weather make it easy to get and keep a beautiful garden. A wide variety of flowers, plants, and veggies thrive in the Gulf region. If you've got good soil drainage, you can even grow citrus trees. You'll have excellent results with peppers of all colors and heat levels, 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 when the threat of frost is gone for the season.

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 pack and give it a try.

Your seeds might get washed away or struggle to grow, or rodents or insects might eat the sprouts. But if you're really fortunate, you might get strong sprouts, 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 sunlight and rain. Keep your seeds cozy with heating 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
Place your transplants in the ground, then water them well. Blanket the surrounding area with mulch, marking where the plant is with a stick or tag so you can easily find it among the grass clippings, old leaves, or straw. If your yard is regularly visited by rabbits, squirrels, deer, or chipmunks, consider putting up chicken wire or other protective measures so your plants and veggies are less likely to get eaten before they thrive.

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

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

Frequently Asked Questions About Gardening

How do I know what planting zone I'm in?

Check the USDA planting zone map, as planting zones have shifted over the years. Zones with higher numbers can plant earlier in the year. Increase your odds of successful gardening by choosing plants that are meant for your zone.

What's direct sow in gardening?

If the soil is pliable and warm, consider planting your fruit, veggie, or flower seeds directly into your garden. This is called the "direct sow" method. The time to plant will be after the threat of frost is gone for the season, as sprouts and seedlings can't weather those conditions. You can also start your seeds indoors if you'd like. Consult your seed packet for when and how to sow seeds.

Do you carry organic plants and seeds?

Yes, we've got a variety of organic options, including organic fruit seeds and veggie seeds, and organic flower and herb seeds which are subject to availability. We carry the organic soil to plant it in as well as the organic fertilizer to feed it.

Should I harden off my seedlings before planting them outside?

Yes, if you raised plants indoors from seeds, harden them before you transplant them. Hardening is the process of getting them used to outdoor life and the fluctuating spring weather. It slows their growth until they're strong and ready to take off during a spring warm front. Hardening also makes your plants more resilient to a sudden cold snap.

Can I strengthen my seedlings before planting them outdoors?

Get your sprouts used to breezy spring days and storms with a fan and keep fungus from growing in damp conditions. Set up an oscillating floor fan on low to mimic the wind. Just the gentlest breeze for several hours a day will do the trick. This makes them stronger against wind gusts. If you don't set up a fan, your seedlings may be more sensitive to strong winds. Try to plant between storms.

What are seed tapes?

If you're dealing with extremely tiny seeds or want more guidance in planting, consider seed tapes. They're biodegradable pieces of paper with tiny seeds affixed at regular intervals. Just bury the tape and water as directed. If all goes well, you'll have perfectly spaced sprouts pop up soon.
