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.
Which planting zone am I in?
Check the USDA plant hardiness zone map, as planting zones have shifted over 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.
When can I plant seeds outside in the spring?
If the soil isn't cold and frozen, consider planting your veggie, fruit, 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 sprouts and seedlings can't weather those conditions. You can also start your seeds indoors if you'd like. Consult your seed packet for how and when to sow seeds.
How do I plant fruit seeds?
Check your seed packet for the best info on how to grow fruits, veggies, and spring flowers — indoors or outdoors. Requirements vary with each seed type. Certain 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 before you transplant them. Hardening is the process of getting them used to outdoor life, spring rains, 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.
Can 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. This makes them stronger against wind gusts. 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. 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.
Celebrate Springtime Gardening
It's time to start thinking of spring. Sweep the gazebo and clean out the shed to prepare for warmer temperatures, fragrant breezes, 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 flowers when the frosts are through and the ground thaws. You might even want to plant organic 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 know when planting veggies, 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. For best results, choose plants in your zone number or less. 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. Be sure to read your seed packet for details. If you start plants 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, 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 direct sowing or starting your seeds indoors.
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. Squash, tomatoes, onions, peppers, cucumbers, 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
You can save money and gain the satisfaction of growing 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 warming 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 White Marsh 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 inch-tall micro-seedlings are fragile but resilient. Seedlings certainly don't get all this pampering in nature when they volunteer and grow wherever, 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
By now, your plants have 3 or 4 true leaves — they'll look different from the miniature seedling leaves. When you're not expecting soaking rain, and the ground is warm, look into transplanting your big sprouts into their new outdoor home. "Transplant" means that you put these small plants straight into pots or garden soil. In cases where you direct sowed, you may still want to shuffle plants around for the best spacing and sun. That's also a transplant situation, as is repotting plants into larger pots.
Protect Your Garden With Mulch
Finish your garden bed with mulch and compost. Mulch controls weeds and keeps the soil moist. Compost enriches the soil so your garden can grow even better. It may help foster larger plants that bear more fruit and flowers. Compost and mulch 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 perfect 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 a pellet grill or artificial grass to your outdoor space. Shop for the soil, seeds, and fertilizer you need in the aisles of your White Marsh Garden Center, online, or on our mobile app. Let's get growing together.
