Mother and child gardening with tools

On those beautiful days, clean up the yard before everything blooms in earnest. Lawn care is often a priority, as well. Planning your garden lets you make the most of your time and space. You can also add beauty and interest with hardscaping, stonework, and water features. No matter what outdoor projects you choose to tackle, The Home Depot Mundelein Garden Center can help you enjoy your spring activities to the fullest.

Plant Hardiness Zones Explained
The first thing you should 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 planting 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 6 garden can support plants listed as Zones 1–6. You can plant seeds indoors roughly a month before you can plant them outside, or direct sow. Be sure to read your seed packet for details. If you start seeds a little 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 kale, cabbage, and broccoli. Greens like spinach, artichokes, and fragrant herbs, including oregano, basil, and parsley, 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. 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 pots or trays 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
Prepare your seed sprouts for outdoor life while they're still indoors. 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
Harden your seedlings for strong plants. On days that are warmer than 45–50 degrees, take your trays or pots of seedlings outside to slowly warm in the shade for two hours, but bring them inside at night. Cloudy days are fine, but no direct sunlight or harsh nighttime chills yet. After a week or more of this, you can leave them out overnight if the temps stay at 50 degrees or above at night. Cover your plants if they're in the ground and a late-season frost sneaks back in.

Transplant Young Plants Into Their New Homes
Place your transplants in the ground, then water them well. Blanket the surrounding area with mulch, marking where the plant is with a stick or tag so you can easily find it among the grass clippings, old leaves, or straw. Consider putting up chicken wire or other protective measures if rodents or deer visit your yard regularly, as your sprouts may otherwise become a snack.

Protect Your Garden With Mulch
Finish your garden bed with mulch and compost. 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 flowers and fruit. 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
Late winter into early spring is an exciting time in the world of gardening. Don't miss a minute of growing season. Prepare to fertilize your lawn, plan your garden and landscaping, and browse our garden center pages to find inspiration on what to plant when the weather warms. Shop for the fertilizer, soil, and seeds you need in the aisles of your Mundelein Garden Center, online, or on our mobile app. Let's get growing together.

Frequently Asked Questions About Gardening

What number planting zone am I in?

Check the USDA growing 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.

What does direct sow mean?

If the soil is warm and pliable, consider planting your veggie, fruit, 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 how and when to sow seeds.

How do I plant vegetable seeds?

Follow the instructions on your seed package. It'll tell you when to start them indoors and when to direct sow. Generally, you'll add several seeds per planting hole, then push them down with your finger. Mark where you buried the seeds with a toothpick, flag, or twig so you don't accidentally confuse them with weeds later.

Should I harden off my seedlings before planting them outside?

Yes, if you raised plants indoors from seeds, harden them before you transplant them. Hardening allows your seedlings to adjust to outdoor life, spring rains, and temperature swings, making them more resilient against cold snaps. It slows their growth until they're strong and ready to take off during a spring warm front.

What should I check before planting transplants or seeds outside?

Before you plant, make sure that your plant will have the right amount of sun, it's warm enough outside, and the soil is healthy. Check your seed envelope to see if it likes shade, full sun, or partial 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'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.
