Frequently Asked Questions About Gardening

What number planting zone am I in?

Check the USDA planting 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 does direct sow mean?

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

Do you carry organic seeds and plants?

Yes, we've got a variety of organic options, including organic fruit seeds and veggie seeds, as well as organic flower and herb seeds that are subject to availability. We also carry the organic fertilizer to feed your plants and the organic soil to plant them in.

Should I 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 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 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 — no need to prep them for a hurricane. The stems and leaves will get used to blowing in the breeze and not snap when a gust comes through. 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 alike. 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.

The Home Depot Garden Center at Johnston

Celebrate Springtime Gardening
On beautiful spring days, tidy the yard before everything blooms in earnest. Plan your garden to make the most of your time and space. Don't forget to clean out the shed and sweep the gazebo in preparation for spring, too. No matter what outdoor projects you choose to tackle and which plants you need, you'll find that The Home Depot Garden Center in Johnston is the local plant nursery to help you enjoy your spring activities to the fullest.

Plant Hardiness Zones Explained
The first thing to learn when planting spring flowers, veggies, 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 6 garden can support plants listed as Zones 1–6. 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 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 directly sowing them into your garden or starting your seeds indoors.

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. 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 plant nursery. 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 plant pots. If you're planting a larger garden, use seed trays — like the ones you see sprouts in at your Johnston Garden Center — to stay organized and plant tiny soil plugs when the time comes. 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 plant tag or toothpick. 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 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
Be sure to harden your seedlings for best results when they're grown. On days above 45 degrees, take your trays or pots 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 harsh nighttime chills or direct sunlight yet. After a week or more of this, you can leave them out overnight if the temps stay at 50 degrees or above at night. Cover your plants if they're in the ground when 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. If your yard is regularly visited by rabbits, squirrels, deer, or chipmunks, consider putting up chicken wire or other protective measures so your plants and veggies are less likely to get eaten before they thrive.

Protect Your Garden With Mulch
Finish it off with mulch and compost. Mulch keeps your soil moist and controls weeds. Compost enriches the soil so your garden can grow even better. It may help foster stronger and larger plants that bear more flowers and fruit. 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
Late winter into early spring is an exciting time in the world of gardening. 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 balcony or patio. Shop for the fertilizer, seeds, and soil you need in the aisles of your Johnston Garden Center, online, or on our mobile app. Let's get growing together.
