Mother and child gardening with tools

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 annuals and young veggie plants when the frosts are through and the ground thaws. You might even want to directly plant seeds into the earth.

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 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. You'll have good results with plants that have your zone number or less. In other words, a Zone 9 garden can support plants listed as Zones 1–9. 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 later than recommended, it's not ideal, but it should even out as time passes.

Gardening in Your Growing Zone
Much of the Great Plains and Upper Midwest is in Zones 3 through 5. Your best bets for veggies will be root vegetables like beets and carrots, leafy greens including lettuce, and cruciferous veggies like cabbage and kale. You can try squash, too. If you plant outside, prepare for additional warming upkeep when late frost is forecast. Planting dates are similar to Zone 4, that is to say, the target is mid-March through May 1st, depending on whether you’re starting your seeds indoors or directly sowing them into your garden.

The state of Kansas and slightly north of the state line is in Zone 6, so planting can begin earlier there than farther north. The outdoor growing season doesn’t kick off until mid-March or even April, although you can start some veggies by seed halfway through February. Tomatoes, peppers, cucumbers, squash, onions, and other classic garden crops will do well in this region, and most of them can get an early jump on growing indoors before spring really moves in.

Start Seeds Indoors
You can 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. Make sure you have a warm and sunny spot that gets at least 12 hours of light and good soil, a spray bottle of water, and patience. Then you have everything you need to try your hand at growing seeds. Early spring light isn't usually strong enough, so we recommend extra lighting to keep those seeds warm enough to germinate.

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 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 enough. Take wilted plants inside and give them a good drink, making sure they're healthy before returning them outdoors.

Transplant Young Plants Into Their New Homes
Place your transplants in the ground, then water them well. Surround them with mulch, marking where the plant is with a stick or tag so you can easily find it among the grass clippings, old leaves, or straw. Consider putting up chicken wire or other protective measures if rabbits, squirrels, deer, or chipmunks visit your yard regularly, as your sprouts may otherwise become a snack.

Protect Your Garden With Mulch
Finish it off with mulch and compost. Mulch controls weeds and keeps your soil from drying out. Compost enriches the soil so your garden can grow even better. It may help foster stronger and larger plants that bear more flowers and fruit. Compost and mulch 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. 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 soil, seeds, and fertilizer you need in the aisles of your Sioux Falls 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 zone map, as planting zones have shifted slightly through 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.

When can I plant seeds outside?

If the soil is warm and pliable, 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 packet for when and how to sow seeds.

How do I plant seeds?

Read your seed package for info on proper depth, spacing, and how many seeds to sow per hole when planting spring flowers, fruits, and vegetables — indoors or outdoors. Requirements vary from one type of flower, fruit, or veggie plant to the next. Certain seeds should only be sown indoors, and your seed envelope will tell you that, too. For more details, check out how to grow a garden from seeds.

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

Yes, if you raised plants indoors from seeds, harden them first before you transplant them. Hardening is the process of getting them used to the great outdoors. 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.

How do I plant a transplant or baby plant?

Squeeze the plastic around the plant to loosen the soil. Gently coax your transplant and the surrounding clod of dirt out into the palm of your hand, then place it into the hole you dug for it. Make sure the top of your transplant's soil is even with the garden soil, and carefully press the earth into place. Avoid mounding a volcano of dirt around your plant, and don't tamp down the ground too tightly. Your plant baby needs to breathe.

Should I use peat moss starters or coir starters?

Seed starters, full of nutrients in convenient 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 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.
