Frequently Asked Questions About Gardening

What number planting zone am I 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 does direct sow mean?

If the soil is warm and pliable, consider planting your flower, veggie, or fruit 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.

How do I plant flower seeds?

Follow the directions on your seed package. It'll tell you when to start them indoors and when to direct sow. Generally, you'll add 3 to 5 seeds per planting hole, then press them into the soil as directed. Mark where you buried the seeds with a wooden craft stick, twig, or flag so you don't think they're weeds later.

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 allows your seedlings to adjust to outdoor life and the fluctuating spring weather, 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.

How do 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.

Should I use peat moss starters or coir starters?

Seed starters, full of nutrients in pots or pellets, 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 cucumbers and eggplant, 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.

Mother and child gardening with tools

It's time to start thinking of spring. We're here to help you prepare for fragrant breezes, warmer temperatures, and sprouts poking up out of the ground. Planting seeds indoors with grow lights means you'll be ready to transplant young veggie plants and spring flowers 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 you should know when planting spring flowers, veggies, 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 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 9 garden can support plants listed as Zones 1–9. 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 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 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 basil, parsley, 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 and gain the satisfaction of growing 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 planter pots. If you're planting a larger garden, use seed trays — like the ones you see sprouts in at your Merchant's Walk 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 plant tag or toothpick. That way, you'll know where your seeds should pop up. 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 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
Once your seedlings have sprouted and are a few inches tall, start hardening them off. This is a process of gradually introducing them to the outdoors, making 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
When your plants have three or four real leaves — different from mini seedling leaves – it's time to transplant them. In quality soil, dig a hole that's 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 fertilizer as directed. Only apply as much as recommended, as you could burn and kill the plant instead of helping it.

Protect Your Garden With Mulch
Finish it all off 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 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. 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 Merchant's Walk Garden Center, online, or on our mobile app. Let's get growing together.
