Set Up For Springtime
It's time to start thinking of spring. Clean the shed and sweep out the gazebo to prepare for sprouts poking up, warmer temperatures, and fragrant breezes. Planting seeds indoors means you'll be ready to transplant young veggie plants and spring flowers when the frosts are through and the ground thaws. You might even want to plant seeds directly into the earth. What better way to start than by exploring your favorite local plant nursery, The Home Depot Keller Garden Center?

Plant Hardiness Zones Explained
The first thing you should 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 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. The plants that'll thrive in your area are in your zone — plus all the zones numbered less than that. 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 plants later than recommended, it's not ideal, but it will likely even out as time passes.

Gardening in Your Growing Zone
If you're in Zone 6–8, check out cruciferous veggies and certain herbs if you're ready to get planting. This includes broccoli, kale, and cabbage. Greens like spinach, artichokes, early-blooming annuals like marigolds, and fragrant herbs, including basil, parsley, and oregano, also don't mind an early beginning. Traditional garden vegetables like peppers of all kinds, cucumbers, and tomatoes are fine with an early spring or late winter planting indoors under the grow lights.

Look up the date of your last predicted frost, then count backward 6 to 8 weeks. That's when you should start your seeds indoors. The idea is to have strong baby plants that are ready for transplant at the same time the ground is warm enough. Do your best and enjoy the process — watching your plants grow, bloom, and put out tiny veggies that'll grow to harvest size is part of the fun.

Start Seeds Indoors
Grow your garden from seeds by starting them indoors in your own seedling garden. 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 plant pots. If you're planting a larger garden, use seed trays — like the ones you see sprouts in at your Keller Garden Center — to stay organized and plant tiny soil plugs when the time comes. 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 micro-seedlings are fragile — only an inch or so high, with the tiniest seedling leaf or two — but they're resilient. Seedlings certainly don't get all this pampering in nature, 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 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 healthy before setting them outdoors again.

Transplant Young Plants Into Their New Homes
You've raised your baby plants from seeds, watched them sprout, and carefully hardened them off to brave Mother Nature. By now, your plants have three or four real leaves — they'll look different from the miniature seedling leaves. When the ground is warm, and you're not expecting soaking rain, look into transplanting your small plants into their new outdoor home. These large seedlings that are ready to be planted can also be called "transplants" or "starts." In cases where you direct sowed, you may still want to shuffle plants around for the best sun and spacing. That's also a transplant situation, as is repotting plants into larger pots.

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 flowers and fruit. Mulch controls weeds and keeps your soil from drying out. 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
Don't miss a minute of growing season. Plan your garden and landscaping, prepare to fertilize your lawn, and browse The Home Depot nursery to find inspiration on what to plant when the weather warms. For those without lawns, consider adding an outdoor rug, artificial grass, or a pellet grill to your patio or balcony. Shop for the fertilizer, soil, and seeds you need in the aisles of your Keller Garden Center, online, or on our mobile app. Let's get growing together.
