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.
What planting zone am I in?
Check the USDA 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.
Is it ok to plant seeds outside in the spring?
If the soil isn't frozen or cold, consider planting your veggie, fruit, 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 sprouts and seedlings can't weather those conditions. You can also start your seeds indoors if you'd like. Consult your seed envelope for how and when to sow seeds.
How do I plant flower seeds?
Follow the instructions on your seed package. It'll tell you when to start them indoors and when to plant them outside. Generally, you'll add several seeds per planting hole, then press them into the soil at the correct depth. Mark where you buried the seeds with a flag, toothpick, or twig so you don't think they're 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. 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 tender seedlings.
What should I do before planting transplants or seeds outside?
Before you plant, make sure that the soil is healthy, it's warm enough outside, and your plant will have the right amount of sun. Check your seed envelope to see if it likes full sun, shade, or partial sun, as well as what time of year it should be planted. Space your plants as described for best results so your plant babies have room to flourish.
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 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.
Celebrate Springtime Gardening
It's time to start thinking of spring. Clean the shed and sweep out the gazebo to prepare for sprouts poking up, warmer temperatures, and fragrant breezes. Planting seeds indoors near a sunny window means you'll be ready to transplant young veggie plants and spring annuals when the ground thaws and the frosts are through. You might even want to sow seeds directly into the earth. What better way to start than by exploring your favorite local plant nursery, The Home Depot Garden Center in West Mifflin?
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 into blocks 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 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 them 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 cabbage 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 direct sowing 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. Tomatoes, peppers, cucumbers, squash, onions, 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. Veteran planters and new gardeners alike should disinfect seed trays with a watered-down bleach solution before reusing them each year. When your trays or pots are prepared, plant your seeds. As for the soil, test the mineral levels and pH to find if it needs amendments or additives. Soil pH differs among regions, and what your plants need depends on what you're growing. Most veggie plants prefer a pH of 5.5–7.5. Soil amendments can tip the balance of your soil in a direction that'll help your plants.
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 toothpick or plant tag. That way, you'll know where your seeds should pop up. 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 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 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 pots or trays 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, incorporating a little sun to get your plants used to it. 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
When your plants have three or four real leaves — different from miniature seedling leaves — transplant them. In quality soil, dig a hole the same size as the dirt plug where your transplant has been growing. If your ground soil isn't great, dig a slightly bigger hole and fill the extra room with nutrient-rich topsoil. Apply any fertilizer as directed on the package, either on top of the soil after it's planted or in the hole. Only apply as much as recommended, as you could burn the plant and kill it instead of helping it.
Protect Your Garden With Mulch
Finish your planting by following it with compost and mulch. Compost enriches the soil so your garden can grow even better. It may help foster larger plants that bear more flowers and fruit. Mulch controls weeds and keeps your soil from drying out. 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
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, fertilizer, and soil you need in the aisles of your West Mifflin Garden Center, online, or on our mobile app. Let's get growing together.
