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 means you'll be ready to transplant spring flowers and young veggie plants when the ground thaws and the frosts are through. 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 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. You'll have good results with plants that have your zone number or less. In other words, a Zone 5 garden can support plants listed as Zones 1–5. The timeframe to direct sow outdoors in your garden is often around a month later than the indoor start date. Be sure to read your seed packet for details. If you start plants a little 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 valley, lake, or wetland, 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 parsley, basil, 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 after the last frost.

Plant Seeds Outside With Direct Sow
Planting seeds into your garden soil, or using the direct sow method, is an alternative option. There's less tending and planning than growing indoors. If you like to go with the flow, follow the instructions on your seed pouch and give it a try.

Prepare to deal with whatever hand nature deals you: Be ready for none of your seeds to sprout, all of them to come up, and anything in between. Your seedlings will need to survive wind, rain, critters and bugs that crave tender greens, and sudden cold temperatures. But if you're lucky, you'll get strong sprouts that are ready to grow all spring.

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 sun and rain. 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
When your plants have three or four true leaves — different from mini seedling leaves – it's time to transplant them. In quality soil, dig a hole the same size as the dirt plug where your transplant has been growing. If your ground soil isn't fantastic, dig a slightly bigger hole and fill the extra space with nutrient-rich topsoil. Apply any fertilizer as directed on the package, either in the hole or on top of the soil after it's planted. Don't apply more than recommended, as you could burn the plant and kill it instead of helping it along.

Protect Your Garden With Mulch
Finish your garden bed with mulch and compost. Mulch keeps your soil moist and controls weeds. 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. Compost and mulch 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 which spring flowers to plant when the weather warms. Shop for the soil, seeds, and fertilizer you need in the aisles of your Alpharetta Garden Center, online, or on our mobile app. Let's get growing together.

Frequently Asked Questions About Gardening

What planting zone am I in?

Check the USDA planting zone map, as planting zones have shifted over the years. Planting 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.

Can I just put seeds in the ground?

If the soil is pliable and warm, consider planting your veggie, fruit, 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 seedlings and sprouts can't weather those conditions. You can also start your seeds indoors if you'd like. Consult your seed package for how and when to sow seeds.

How do I plant veggie seeds?

Follow the instructions on your seed envelope. It'll tell you when to start them indoors and when to plant them outside. Generally, you'll add three to five seeds per planting hole, then press them into the soil as directed. Mark where you buried the seeds with a twig, wooden craft stick, or flag so you don't mistake them for weeds later.

Do I have to harden off my seedlings before planting them outside?

Yes, for best results, if you raised plants indoors from seeds, harden them before you transplant them. Hardening allows your seedlings to adjust to the great outdoors, making them more resilient against cold snaps. It slows their growth until they're strong and ready to take off during a spring warm front.

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 — no need to prep them for a hurricane. They'll gain strength even though you shouldn't see them moving. If you don't set up a fan, your seedlings may be more sensitive to strong winds. Try to plant between storms.

Should I use peat moss starters or coir starters?

Seed starters, full of nutrients in pellets or pots, work for new and experienced gardeners alike. You don't have to use these starters if you're planting in soil, but you may want to. Starting seeds in peat pots works best for delicately rooted plants like carrots and beets, as well as flowers that need acidic soil. Some people prefer coir starters instead, as they have a neutral pH. Check what type of soil your plants need to help narrow it down, and chat with a garden center associate if you need more info.
