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 planting zone?
Check the USDA growing zone map, as planting zones have shifted over the years. Zones with higher numbers can plant earlier in the year. Choose plants that are meant for your zone and increase your odds of successful gardening.
When can I plant seeds outside in the spring?
If the soil is pliable and warm, consider planting your fruit, flower, or vegetable 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 when and how to sow seeds.
Do you carry organic plants and seeds?
Yes, we've got a variety of organic options, including organic veggie seeds and fruit seeds, as well as organic flower and herb seeds that are subject to availability. We carry the organic soil to plant them in as well as the organic fertilizer to feed your plants.
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 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.
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'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, you'll have perfectly spaced sprouts pop up soon.
Set Up For Springtime
On beautiful spring days, tidy the yard before everything blooms in earnest. Lawn care is often a priority as well. Don't forget to sweep out the gazebo and clean the shed 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 Garden Center in Southtown can help you enjoy your spring activities to the fullest.
Plant Hardiness Zones Explained
The first thing you should know when planting spring flowers, vegetables, 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 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. You'll have good results with plants that have your zone number or less. In other words, a Zone 8 garden can support plants listed as Zones 1–8. You can plant seeds indoors roughly a month before you can plant them outside, known as direct sow. 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 broccoli, cabbage, 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.
Start Seeds Indoors
Save money when you grow 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 plant pots. If you're planting a larger garden, use seed trays — like the ones you see sprouts in at your Southtown 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 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 certainly don't get all this pampering in nature, 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
When you're hardening your sprouts and gradually introducing them to the outdoors, be flexible. Keep an eye on your baby plants. If they're looking rough, don't push them. It’s ok to roll back a step or two if need be: Bring them inside overnight or put them in shady places instead of direct sun. As always, make sure they're watered enough. Take wilted plants inside and give them a good drink, making sure they're healthy before setting them outdoors again.
Transplant Young Plants Into Their New Homes
You've raised your baby plants from seeds, watched them sprout, and carefully hardened them off to brave Mother Nature. By now, your plants have 3 or 4 real 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. These large seedlings that are ready to be planted can also be called "transplants" or "starts." 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 it off with compost and mulch. 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 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 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 artificial grass, an outdoor rug, or a pellet grill to your patio or balcony. Shop for the soil, seeds, and fertilizer you need in the aisles of your Southtown Garden Center, online, or on our mobile app. Let's get growing together.
