Mother and child gardening with tools

On those beautiful days, clean up the yard before everything blooms in earnest. Many people feel inspired to refresh their outdoor space for entertaining, as well. Planning your garden lets you make the most of your time and space. Remember to measure your garden so you can find fresh mulch near you as soon as it's available. No matter what outdoor projects you choose to tackle, The Home Depot Gretna Garden Center can help you enjoy your spring activities to the fullest.

Plant Hardiness Zones Explained
The first thing to know 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 planting 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. You can plant seeds indoors roughly a month before you can plant them outside, or direct sow. Always read your seed packet for details. If you start seeds a little later than recommended, it's not ideal, but it will likely 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 mountain, 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.

Start Seeds Indoors
Save money when you 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 grow lights or a warming mat to go with your seed tray or planters. If you're planting a larger garden, use seed trays — like the ones you see sprouts in at your Gretna Garden Center — to make it easy to stay organized and plant tiny soil plugs later. You can also use pots with seed starter mix and potting soil.

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 plant tag or toothpick. That way, you'll know where your seeds should pop up, and you'll know they're not weeds. Otherwise, it'll be a surprise when the sprouts push out of the soil.

Sprouts
When your seeds have sprouted but aren't ready to go outside yet, you can still prepare them for outdoor life. These inch-tall micro-seedlings are fragile but 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
When you're hardening your sprouts and gradually introducing them to the outdoors, be flexible. Keep an eye on your baby plants. If they're looking rough, don't push them. It’s ok to roll back a step or two if need be: Bring them inside overnight or put them in shady places instead of direct sun. As always, make sure they're watered just enough, but not too much. Whisk wilted plants inside and give them a good drink, making sure they're strong before returning them outdoors.

Transplant Young Plants Into Their New Homes
When your plants have three or four real leaves — different from miniature 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 room with nutrient-rich topsoil. Apply any fertilizer as directed on the package. Only apply as much as recommended, as you could burn the plant and kill it instead of helping it along.

Protect Your Garden With Mulch
Finish it off with compost and mulch. 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. Mulch keeps your soil from drying out 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 perfect 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. Plan your garden and landscaping, prepare to fertilize your lawn, and browse our garden center pages to find inspiration on which spring flowers to plant when the weather warms. Shop for the seeds, soil, and fertilizer you need in the aisles of your Gretna Garden Center, online, or on our mobile app. Let's get growing together.

Frequently Asked Questions About Gardening

Which planting zone am I in?

Check the USDA plant hardiness 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.

Is it ok to plant seeds outside?

If the soil isn't cold and frozen, consider planting your flower, fruit, or vegetable seeds directly into your garden. This is called the "direct sow" method. Plant 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.

Do you carry organic plants and seeds?

We offer many organic gardening options, including organic veggie seeds and fruit seeds, and organic herb and flower seeds which are subject to availability. We carry the organic soil to plant it in as well as the organic fertilizer to feed it.

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 is the process of getting them used to the great outdoors and rain, sun, and temperature swings. 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. Read your seed packets or speak to a garden center associate for more info on caring for your seedlings.

Can I strengthen my seedlings before planting them outdoors?

Get your sprouts used to storms and breezy spring days 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. 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 want more guidance in planting or are dealing with extremely tiny seeds, 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.
