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 planting 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?
If the soil isn't cold and frozen, consider planting your fruit, flower, or veggie 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 plants and seeds?
We offer many organic gardening options, including organic fruit seeds and veggie seeds, as well as organic herb and flower seeds that are subject to availability. We also carry the organic fertilizer to feed your plants and the organic soil to plant them in.
Do I have to 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 the great outdoors and rain, sun, 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.
How do I prep for planting transplants or seeds outside?
Before you plant, make sure that it's warm enough outside, your plant will have the right amount of sun, and the soil is healthy. Check your seed envelope to see if it likes shade, partial sun, or full sun, as well as what time of year it should be planted. Space your plants as described on the seed packet for best results so your plant babies have room to flourish.
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.
Celebrate Springtime Gardening
On beautiful spring days, tidy the yard before everything blooms in earnest. Lawn care is often a priority as well. 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, you'll find that The Home Depot Garden Center in Sunset Hills is the local plant nursery to help you enjoy your spring activities to the fullest.
Plant Hardiness Zones Explained
The first thing you should know when planting veggies, 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 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. 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
This area is primarily in Zone 6, with Zone 5 starting in Central Illinois, slightly north of Peoria and Bloomington-Normal. The outdoor growing season doesn't begin here until mid-March or even April, although you can plant some veggie seeds halfway through February. Tomatoes, peppers, cucumbers, squash, 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.
Also, check out cruciferous veggies and certain herbs if you're ready to get planting. This includes cabbage, broccoli, and kale. Greens like spinach, artichokes, and fragrant herbs, including parsley, basil, and oregano, also don't mind an early beginning. The main concern is waiting until the frost has passed for the season, so planting seeds outdoors as direct sow is later here compared to farther south.
Plant Seeds Outside With Direct Sow
Planting seeds into your garden soil, or using the direct sow method, is an alternative option. There's less planning and tending than growing indoors. If you like to go with the flow, follow the instructions on your seed package and try it out.
Your seeds might struggle to grow or get washed away, or bugs or critters might eat the sprouts. But if you're really lucky, you might get strong sprouts, perfectly spaced and ready to grow all spring. The reality of your sown seeds will usually be somewhere in between, and spreading out tiny sprouts throughout the soil isn't so bad. You know those sprouts are primed to survive and hardy, although there are no guarantees.
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 rain and sun. Keep your seeds cozy with heating 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
Carefully take your seedling out of the container. Turn it upside-down or sideways and gently squeeze the plastic to break the seal. If your transplant grew in the garden, leave plenty of room around the stem and dig deeper than you think with your garden trowel. You don't want to damage the roots. Place it into the hole you dug for it, even with the surrounding soil.
Protect Your Garden With Mulch
Finish it off with compost and mulch. Mulch keeps your soil moist and controls weeds. Compost enriches the soil so your garden can grow even better. It may help foster larger and stronger plants that bear more fruit and flowers. Mulch and compost 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. Prepare to fertilize your lawn, plan your garden and landscaping, 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, a pellet grill, or an outdoor rug to your balcony or patio. Shop for the seeds, soil, and fertilizer you need in the aisles of your Sunset Hills Garden Center, online, or on our mobile app. Let's get growing together.
