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. Plan your garden to make the most of your time and space. You can also add beauty and interest with hardscaping, stonework, and water features. No matter what outdoor projects you choose to tackle, The Home Depot Garden Center in Ellisville can help you enjoy your spring activities to the fullest.

Plant Hardiness Zones Explained
The first thing to know when planting veggies, 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 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 6 garden can support plants listed as Zones 1–6. 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 seeds a little later than recommended, it's not ideal, but it will even out as time passes.

Gardening in Your Growing Zone
This area is primarily in Zone 6, with Zone 5 starting in Central Illinois, slightly north of Peoria and Bloomington-Normal. The outdoor growing season doesn’t begin here until mid-March or even April, although you can plant some veggie seeds halfway through February. Tomatoes, peppers, cucumbers, squash, and other classic garden crops will do well in this region, and most of them can get an early start indoors before spring really moves in.

Also, check out cruciferous veggies and certain herbs if you’re ready to get planting. This includes broccoli, kale, and cabbage. Greens like spinach, artichokes, and fragrant herbs, including oregano, basil, and parsley, also don't mind an early beginning. The main concern is waiting until the frost has passed for the season, so planting seeds outdoors as direct sow is later here compared to farther south.

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 Ellisville 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. 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 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. Bring them inside or move them to a shady spot if they're looking rough. As always, make sure they're watered just enough, but not too much. Take 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 mini seedling leaves – 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 any fertilizer as directed on the package. Only apply as much as recommended, as you could burn and kill the plant instead of helping it along.

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

Greet the Spring
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 what to plant when the weather warms. Shop for the fertilizer, soil, and seeds you need in the aisles of your Ellisville Garden Center, online, or on our mobile app. Let's get growing together.

Frequently Asked Questions About Gardening

What number planting zone am I in?

Check the USDA 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.

Can I just put seeds in the ground?

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

Do you carry organic seeds and plants?

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, 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.

How do I prepare for planting seeds or transplants outside?

Before you plant, make sure that your plant will have the right amount of sun, it's warm enough outside, and the soil is healthy. Check your seed package to see if it likes shade, full sun, or partial sun, as well as what time of year it should be planted. Space your plants as described for best results so your plant babies have room to flourish.

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 carrots and beets, as well as flowers that require an acidic pH. 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.
