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 check my USDA planting zone?
Check the USDA planting zone map, as planting zones have changed slightly 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.
When can I plant seeds outside?
If the soil is warm and pliable, 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 packet for when and how to sow seeds.
How do I plant seeds?
Check your seed packet for the best info on how to grow fruits, veggies, and spring flowers — indoors or outdoors. Requirements vary from one type of plant to the next. Some seeds should only be planted indoors, and your seed package 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, 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.
What are seed tapes?
If you're dealing with extremely tiny seeds or want more guidance in planting, 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, your perfectly spaced sprouts will pop up soon.
Set Up For Springtime
On beautiful spring days, tidy the yard before everything blooms in earnest. Remember to measure your garden so you can find fresh mulch near you as soon as it's available. Don't forget to clean the shed and sweep out the gazebo in preparation for spring, too. No matter what outdoor projects you choose to tackle and which plants you need, search for your local plant nursery and find that The Home Depot Hamilton Garden Center can 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 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. You'll have good results with plants that have your zone number or less. In other words, a Zone 7 garden can support plants listed as Zones 1–7. The timeframe to direct sow outdoors in your garden is often around a month later than the indoor start date. Read your seed packet for details. If you start them a little later than recommended, it's not ideal, but it should 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. 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, Connecticut, Massachusetts, southern New York state, and New Jersey 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.
Plant Seeds Outside With Direct Sow
Planting seeds into your garden soil, or using the direct sow method, is an alternative option. It doesn't give you as much organized planning in terms of space and reliability as starting indoors. However, if you like to go with the flow, follow the instructions on your seed pack and give it a try.
Prepare to deal with whatever hand nature deals you: You might have no germinating seeds. A critter may snack on the tender seedlings. All the seeds you plant in each hole may sprout, so you'll need to thin them out by only leaving the most robust sprouts. Flooding rains might disturb the ground and wash away the seeds. But if you're lucky, you'll get strong sprouts that are ready to grow all spring.
Start Seeds Indoors
If you'd like more control over your seedlings' journey or you're eager to get growing, start your seeds indoors in your own plant nursery. In general, you can plant seeds indoors about a month before you can do it outside. Like direct sow, you push the seeds into the soil as directed on the seed packet, but that's where the similarities end.
You're responsible for giving them quality substitutes for sunlight and rain. Keep your seeds cozy with warming mats and grow lights, water them carefully with a spray bottle or watering can, then thin them as they germinate in groups of three. Give them a boost with a gently blowing fan as they lengthen into sprouts if you'd like. Harden them off to get them used to outdoor conditions, then transplant them into your garden when they're big enough.
Transplant Young Plants Into Their New Homes
When your plants have three or four real leaves — different from mini seedling leaves — transplant them. In quality soil, dig a hole that's 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 space with nutrient-rich topsoil. Apply fertilizer as directed, either on top of the soil after it's planted or in the hole. Only apply as much as recommended, as you could burn and kill the plant instead of helping it.
Protect Your Garden With Mulch
Finish off your garden with compost and mulch. Compost enriches the soil so your garden can grow even better. It may help foster larger plants that bear more fruit and flowers. Mulch keeps your soil moist and controls weeds. 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. Prepare to fertilize your lawn, plan your garden and landscaping, and browse The Home Depot nursery to find inspiration on which spring flowers to plant when the weather warms. For those without lawns, consider adding artificial grass or a pellet grill to your outdoor space. Shop for the seeds, soil, and fertilizer you need in the aisles of your Hamilton Garden Center, online, or on our mobile app. Let's get growing together.
