It's time to start thinking of spring. We're here to help you prepare for sprouts poking up, fragrant breezes, and warmer temperatures. 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 seeds into the earth.

Plant Hardiness Zones Explained
The first thing to learn when planting spring flowers, vegetables, 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 plant hardiness 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. For best results, choose plants in 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. Be sure to read your seed packet for details. If you start seeds a little later than recommended, it's not ideal, but it should even out as time passes.

Gardening in Your Growing Zone
In Zone 5, which includes parts of Pennsylvania as well as upstate New York, Vermont, New Hampshire, and southern Maine, 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, but prepare for additional warming upkeep when late frost is forecast. Planting dates are roughly mid-March through May 1st, depending on whether you're starting your seeds indoors or direct sowing.

Much of Ohio, Pennsylvania, West Virginia, Massachusetts, New Jersey, southern New York state, and Connecticut are in Zone 6, so planting can begin earlier there than farther north. Parts of Virginia are even warmer, coming in at Zone 7. The outdoor growing season doesn't begin until mid-March or even April, although you can plant some veggie seeds halfway through February. Tomatoes, peppers, cucumbers, squash, onions, and other classic garden crops will thrive in this region, and most of them can get an early start indoors before spring really moves in.

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 planter pots. If you're planting a larger garden, use seed trays — like the ones you see sprouts in at your Glasgow 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 toothpick or plant tag. 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 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
Harden your seedlings for best results later. On days above 45 degrees, take your trays or pots of seedlings outside to slowly warm in the shade for two hours, but bring them inside at night. Cloudy days are fine, but no harsh nighttime chills or direct sunlight yet. After a week or more of this, you can leave them out overnight if the temps stay warmer than 50 degrees. Cover your plants if they're in the ground and a late-season frost sneaks back in.

Transplant Young Plants Into Their New Homes
When your plants have three or four true leaves — different from miniature seedling leaves – it's time to transplant them. In quality soil, dig a hole 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 fertilizer as directed. Don't apply more than recommended, as you could burn and kill the plant instead of helping it.

Protect Your Garden With Mulch
Finish your flower bed with mulch and compost. Compost enriches the soil so your garden can grow even better. It may help foster larger plants that bear more fruit and flowers. 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 right amount.

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