Mother and child gardening with tools

It's time to start thinking of spring. We're here to help you prepare for fragrant breezes, warmer temperatures, and sprouts poking up out of the ground. Planting seeds indoors with grow lights means you'll be ready to transplant young veggie plants and spring annuals when the ground thaws and the frosts are through. You might even want to directly sow seeds into the earth.

Plant Hardiness Zones Explained
The first thing to know when planting vegetables, 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 growing 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. The plants that'll thrive in your area are in your zone, and all the zones numbered less than that. In other words, a Zone 5 garden can support plants listed as Zones 1–5. The timeframe to direct sow outdoors in your garden is often around a month later than the indoor start date. 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
In Zone 5, which includes parts of Pennsylvania as well as upstate New York, New Hampshire, Vermont, and southern Maine, your best bets for veggies will be root vegetables like beets and carrots, leafy greens including lettuce, and cruciferous veggies like broccoli and kale. You can try squash, but prepare for additional warming upkeep when late frost is forecast. Target planting dates are roughly mid-March through May 1st, depending on whether you're starting your seeds indoors or directly sowing them into your garden.

Much of West Virginia, Ohio, Pennsylvania, 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, cucumbers, peppers, 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
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. For best results, you'll want grow lights or a warming mat to go with your seed tray or planters. If you're planting a larger garden, use seed trays — like the ones you see sprouts in at your North Windham 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
When your seeds have sprouted but aren't ready to go outside yet, you can still prepare them for outdoor life. 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 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 fan on low to mimic the wind and strengthen their stems.

Harden Your Seedlings
Harden your seedlings for strong plants. 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. A cloudy day will also work well. Gradually add an extra hour or two each day, gently introducing your plants to the sun. 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
By now, your plants have 3 or 4 true 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. "Transplant" means that you put these small plants straight into the garden soil or into pots. 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 all off with compost and mulch. 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 plants that bear more fruit and flowers. Compost and mulch 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 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 fertilizer, soil, and seeds you need in the aisles of your North Windham 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 planting zone map, as planting zones have shifted slightly through 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 isn't cold and frozen, 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 sprouts and seedlings can't weather those conditions. You can also start your seeds indoors if you'd like. Consult your seed envelope for how and when to sow seeds.

How do I plant seeds?

Follow the advice on your seed packet. It'll tell you when to start them indoors and when to direct sow. Generally, you'll add several seeds per planting hole, then push them down with your finger. Mark where you planted them with a twig, wooden craft stick, or flag so you don't think they're weeds later.

Should I 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 and sun, rain, 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.

What do I do before planting transplants or seeds outside?

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