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's my planting zone?
Check the USDA zone map, as planting zones have shifted over the years. Planting zones with higher numbers can plant earlier in the year. Choose plants that are meant for your zone and increase your odds of gardening success.
What's direct sow?
If the soil is pliable and warm, consider planting your flower, fruit, or veggie 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 package for how and when 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 flower and herb 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 plant a transplant or baby plant?
Squeeze the plastic around the plant to loosen the soil. Carefully coax the plug of dirt with the plant into your palm, then place it into the hole you dug for it. Make sure the top of your transplant's soil is even with the garden soil, and carefully press the earth into place. Avoid leaving the plant as an island in a puddle of water, and don't tamp down the ground too tightly. Your plant baby needs to breathe.
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, your perfectly spaced sprouts will pop up soon.
Set Up For Springtime
On beautiful spring days, tidy the yard before everything blooms in earnest. Plan your garden to make the most of your time and space. Don't forget to sweep out the gazebo and clean the shed in preparation for spring, too. No matter which plants you need and what outdoor projects you choose to tackle, you'll find that The Home Depot Arnold Garden Center is the local plant nursery to help you enjoy your spring activities to the fullest.
Plant Hardiness Zones Explained
The first thing to know 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 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 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 likely 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, kale, and cabbage. Greens like spinach, artichokes, and fragrant herbs, including basil, parsley, 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
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, check to see if yours needs nutrient balancing. Choose fertilizers that match what you're growing. It'll help give your plants everything they need to grow big and strong.
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. 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 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
When your plants have three or four real leaves — different from mini 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 fantastic, dig a slightly bigger hole and fill the extra space with nutrient-rich topsoil. Apply fertilizer as directed. Don't apply more than recommended, as you could burn the plant and kill it instead of helping it along.
Protect Your Garden With Mulch
Finish it all 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 stronger plants that bear more fruit and flowers. Compost and mulch 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 perfect 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 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 seeds, fertilizer, and soil you need in the aisles of your Arnold Garden Center, online, or on our mobile app. Let's get growing together.
