Frequently Asked Questions About Gardening

Which planting zone am I in?

Check the USDA growing zone map, as planting zones have shifted over the years. Zones with higher numbers can plant earlier in the year. Choose plants that are meant for your zone and increase your odds of gardening success.

What's direct sow?

If the ground isn't frozen solid and the soil isn't cold, consider planting your fruit, veggie, or flower 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 seeds?

Follow the directions on your seed envelope. It'll tell you when to start them indoors and when to direct sow. Generally, you'll add three to five seeds per planting hole, then press them into the soil as directed. Mark where you buried the seeds with a wooden craft stick, flag, or twig so you don't confuse them with weeds later.

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

Yes, for best results, if you raised plants indoors from seeds in your own plant nursery, harden them before you transplant them. Hardening is the process of getting them used to the great outdoors and rain, sun, and temperature swings. 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. Read your seed packets or speak to a garden center associate for more info on caring for your tender seedlings.

Can I strengthen my seedlings before planting them outdoors?

Get your sprouts used to breezy spring days and storms 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. 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 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 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.

Celebrate Springtime Gardening
It's time to start thinking of spring. Sweep out the gazebo and clean the shed to prepare for sprouts poking up, warmer temperatures, and fragrant breezes. Planting seeds indoors with grow lights means you'll be ready to transplant young veggie plants and spring flowers when the frosts are through and the ground thaws. You might even want to plant seeds directly into the earth. What better way to start than by exploring your favorite local plant nursery?

Plant Hardiness Zones Explained
The first thing to learn 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 plant hardiness 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 — plus 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 a little later than recommended, it's not ideal, but it will likely 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 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. Squash, tomatoes, onions, cucumbers, peppers, and other classic garden crops will do well 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 in your own seedling garden. 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. Then you have everything you need to try 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. That way, you'll know where your seeds should pop up, and you can be sure they're not weeds. 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 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
Be sure to harden off your seedlings once they're a few inches tall. This is a process of gradually introducing them to the outdoors, making 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
Place your transplants in the ground, then give them a generous drink without overwatering. Blanket the surrounding area with mulch, marking where the plant is with a tag or stick 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 your flower bed 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 stronger and larger plants that bear more fruit and flowers. Mulch and compost 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
Don't miss a minute of growing season. Plan your garden and landscaping, prepare to fertilize your lawn, and browse The Home Depot nursery to find inspiration on what to plant when the weather warms. For those without lawns, consider adding artificial grass, an outdoor rug, or a pellet grill to your patio or balcony. Shop for the seeds, soil, and fertilizer you need in the aisles of your Somersworth Garden Center, online, or on our mobile app. Let's get growing together.
