Frequently Asked Questions About Gardening
Which planting zone am I in?
Check the USDA planting zone map, as planting zones have changed slightly 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.
When can I plant seeds outside in the spring?
If the ground isn't frozen solid and the soil isn't cold, consider planting your flower, veggie, or fruit 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 packet for how and when to sow seeds.
Do you carry organic seeds and plants?
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.
Should I harden off my seedlings before planting them outside?
Yes, for best results, if you raised plants indoors from seeds in your own plant nursery, harden them before you transplant them. Hardening is the process of getting them used to the great outdoors. 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.
Should I use peat moss starters or coir starters?
Seed starters, full of nutrients in convenient pellets or pots, work for new and experienced gardeners. You don't have to use these starters if you're planting in soil, but you may want to. Starting seeds in peat pots works best for delicately rooted plants like carrots and beets, as well as flowers that need acidic soil. Some people prefer coir starters instead, as they have a neutral pH. Check what type of soil your plants need to help narrow it down, and chat with a garden center associate if you need more info.

Celebrate Springtime Gardening
It's time to start thinking of spring. Clean the shed and sweep out the gazebo to prepare for sprouts poking up, fragrant breezes, and warmer temperatures. Planting seeds indoors with grow lights means you'll be ready to transplant young veggie plants and spring flowers when the ground thaws and the frosts are through. You might even want to sow seeds directly into the earth. What better way to start than by exploring your favorite local plant nursery?
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 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. 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. You can plant seeds indoors roughly a month before you can plant them outside, known as direct sow. Be sure to read your seed packet for details. If you start them 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. Make sure you have a warm and sunny spot that gets at least 12 hours of light and a spray bottle of water, good soil, and patience. Then you have everything you need to try your hand at growing seeds. Early spring light isn't usually strong enough, so we recommend extra lighting to keep those seeds warm enough to germinate.
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 plant tag or toothpick. That way, you'll know where your seeds should pop up, and you can be sure they're not weeds. 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 inch-tall micro-seedlings are fragile but resilient. Seedlings 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 floor fan on low to mimic the wind and strengthen their stems.
Harden Your Seedlings
Make sure to harden your seedlings for best results when they're grown. On days that are warmer than 45–50 degrees, take your pots or trays 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 when a late-season frost sneaks back in.
Transplant Young Plants Into Their New Homes
By now, your plants have three or four true 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. "Transplant" means that you put these small plants straight into the garden soil or into pots. In cases where you directly planted into the ground, you may still want to shuffle plants around for the best sun and spacing. That's also a transplant situation, as is repotting plants into larger pots.
Protect Your Garden With Mulch
Finish it off with mulch and compost. Compost enriches the soil so your garden can grow even better. It may help foster stronger and larger plants that bear more flowers and fruit. Mulch controls weeds and keeps your soil from drying out. 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. 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 an outdoor rug, artificial grass, or a pellet grill to your patio or balcony. Shop for the soil, seeds, and fertilizer you need in the aisles of your St Charles County Garden Center, online, or on our mobile app. Let's get growing together.
