Frequently Asked Questions About Gardening

What number planting zone am I in?

Check the USDA growing 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.

Can I plant seeds directly in the ground?

If the soil is pliable and warm, consider planting your veggie, flower, or fruit 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 package for when and how to sow seeds.

How do I plant vegetable seeds?

The best source of information is the seed package your garden-to-be came in. It's key to successfully growing spring flowers, fruits, and vegetables — indoors or outdoors. Requirements vary from one type of plant to the next. Certain seeds should only be planted indoors, and your seed packet will tell you that, too. For more details, check out how to plant flower seeds.

Do I have to 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 outdoor life and the fluctuating spring weather, 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.

How do 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 pots or pellets, 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 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.

The Home Depot Garden Center at Roosevelt

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

Plant Hardiness Zones Explained
The first thing you should know when planting spring flowers, veggies, 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 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, and all the zones numbered less than that. In other words, a Zone 9 garden can support plants listed as Zones 1–9. The timeframe to direct sow outdoors in your garden is often around a month later than the indoor start date. 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. 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, New Jersey, Connecticut, southern New York state, and Massachusetts 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 plant pots. If you're planting a larger garden, use seed trays — like the ones you see sprouts in at your Roosevelt 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.

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 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 best results later. On days above 45 degrees, take your pots or trays of seedlings outside to slowly warm in the shade for a couple of hours, but bring them inside at night. Cloudy days are fine, but no direct sunlight or harsh nighttime chills yet. After a week or more of this, you can leave them out overnight if the temps stay above 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
Place your transplants in the ground, then give them a generous drink of water — without drowning it. 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 rodents or deer visit your yard regularly, as your sprouts may otherwise become a snack.

Protect Your Garden With Mulch
Finish it off with compost and mulch. Mulch controls weeds and keeps the soil moist. Compost enriches the soil so your garden can grow even better. It may help foster larger and stronger plants that bear more fruit and flowers. Mulch and compost 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 what to plant when the weather warms. Shop for the fertilizer, seeds, and soil you need in the aisles of your Roosevelt Garden Center, online, or on our mobile app. Let's get growing together.
