When you're ready to seed your lawn, our calculator helps you estimate the amount of grass seed you'll need to get the job done.
Enter your preferred material, the square footage and mulch depth of the coverage space for accurate results.
We'll calculate the amount of fencing you should purchase based on your property needs.
How do I know what planting zone I'm in?
Check the USDA growing zone map, as planting zones have shifted over 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 just put seeds in the ground?
If the soil is warm and pliable, consider planting your veggie, flower, or fruit 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 sprouts and seedlings 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 seeds?
The best source of information is the seed packet your garden-to-be came in. It's key to successfully growing fruits, veggies, and spring flowers — indoors or outdoors. Requirements vary with each seed type. Some seeds should only be sown indoors, and your seed envelope will tell you that, too. You'll be a pro at planting seeds in no time.
Should I harden off my seedlings before planting them outside?
Yes, if you raised plants indoors from seeds in your own plant nursery, harden them first before you transplant them. Hardening is the process of getting them used to outdoor life and the fluctuating spring weather. 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. Speak to a garden center associate or read your seed packets for more info on caring for your 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 — 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.
What are seed tapes?
If you want more guidance in planting or are dealing with extremely tiny seeds, consider seed tapes. They're biodegradable pieces of paper with tiny seeds affixed at regular intervals. Just bury the tape and water as directed. If all goes well, you'll have perfectly spaced sprouts pop up soon.
Set Up For Springtime
It's time to start thinking of spring. Sweep the gazebo and clean out the shed to prepare for fragrant breezes, warmer temperatures, and sprouts poking up out of the ground. Planting seeds indoors near a sunny window means you'll be ready to transplant spring annuals and young veggie plants when the ground thaws and the frosts are through. You might even want to plant seeds directly into the earth. What better way to start than by exploring your favorite local plant nursery, The Home Depot Riverhead Garden Center?
Plant Hardiness Zones Explained
The first thing you should 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. For best results, choose plants in your zone number or less. 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. Always read your seed packet for details. If you start them 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. 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 in your own seedling garden. 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 Riverhead 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. 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
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
Make sure to harden your seedlings for best results when they're grown. On days that are warmer than 45–50 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 when a late-season frost sneaks back in.
Transplant Young Plants Into Their New Homes
Place your transplants in the ground, then water them well. Surround them with mulch, marking where the plant is with a 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 your planting by following it 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 controls weeds and keeps the soil moist. 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
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 a pellet grill or artificial grass to your outdoor space. Shop for the seeds, soil, and fertilizer you need in the aisles of your Riverhead Garden Center, online, or on our mobile app. Let's get growing together.
