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 with grow lights means you'll be ready to transplant spring flowers and young veggie plants when the frosts are through and the ground thaws. You might even want to directly sow seeds into the earth.

Plant Hardiness Zones Explained
The first thing to learn when planting veggies, spring flowers, 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 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. 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 them later than recommended, it's not ideal, but it should even out as time passes.

Gardening in Your Growing Zone
The Midwest is mostly Zones 6 and 7 throughout Indiana, Michigan, and Kentucky. You’ll find pockets of Zone 5 and stretches of Zone 4 in the Upper Peninsula. In Zones 5 and 6, the outdoor growing season doesn’t begin here until mid-March or even April, although you can plant some veggie seeds halfway through February. Warmer Zone 7 can start planting earlier, and Zone 4 much later on. Tomatoes, peppers, cucumbers, squash, and other classic garden crops will thrive in this region, and most of them can get an early jump on growing indoors before spring really moves in.

Also, check out certain herbs and cruciferous veggies if you're ready to get planting. This includes kale, cabbage, and broccoli. Greens like spinach, artichokes, and fragrant herbs, including parsley, basil, and oregano, also don't mind an early start. 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 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 Caledonia Twshp 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 toothpick or plant tag. 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 don't get all this pampering in nature when they volunteer and grow wherever, 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
Harden off your seedlings once they're a few inches tall. This process of gradually introducing them to the outdoors makes 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 miniature 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 great, dig a slightly bigger hole and fill the extra space with nutrient-rich topsoil. Apply any fertilizer as directed on the package, either in the hole or on top of the soil after it's planted. Only apply as much as recommended, as you could burn the plant and kill it instead of helping it.

Protect Your Garden With Mulch
Finish off your garden with compost and mulch. Compost enriches the soil so your garden can grow even better. It may help foster larger plants that bear more flowers and fruit. Mulch keeps your soil moist and controls weeds. 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
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, fertilizer, and seeds you need in the aisles of your Caledonia Twshp 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 plant hardiness 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.

When can I plant seeds outside?

If the soil isn't frozen or cold, 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 seedlings and sprouts 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.

How do I plant flower seeds?

The best source of info is the seed packet your garden-to-be came in. It's key to successfully growing fruits, veggies, and spring flowers — indoors or outdoors. Requirements vary with each seed type. Certain seeds should only be planted indoors, and your seed envelope will tell you that, too. For more details, check out how to start your garden with seeds.

Should I harden off my seedlings before planting them outside?

Yes, for best results, if you raised plants indoors from seeds, harden them first before you transplant them. Hardening allows your seedlings to adjust to outdoor life, spring rains, and temperature swings, 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.

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. They'll gain strength even though you shouldn't see them moving. 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 pellets or pots, work for new and experienced gardeners. 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 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.
