Frequently Asked Questions About Gardening
Which planting zone am I in?
Check the USDA 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.
Is it ok to plant seeds outside?
If the soil isn't cold and frozen, consider planting your fruit, veggie, 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 sprouts and seedlings 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.
How do I plant veggie seeds?
The best source of info is the seed packet your garden-to-be came in. It's key to successfully growing spring flowers, fruits, and vegetables — indoors or outdoors. Requirements vary with each seed type. Some seeds should only be sown indoors, and your seed envelope will tell you that, too. You'll be a pro at planting seeds in no time.
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 first before you transplant them. Hardening allows your seedlings to adjust to the great outdoors and rain, sun, 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.
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 with a moat around it, 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 alike. 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 cucumbers and eggplant, 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.
The Home Depot Garden Center at Cottleville
Set Up For Springtime
On beautiful spring days, tidy the yard before everything blooms in earnest. Remember to measure your garden so you can find fresh mulch near you as soon as it's available. Don't forget to sweep the gazebo and clean out 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 Garden Center in Cottleville is your 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 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. You'll have good results with plants that have your zone number or less. In other words, a Zone 5 garden can support plants listed as Zones 1–5. 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 seeds 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, kale, and cabbage. 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 and gain the satisfaction of growing 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. 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 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 micro-seedlings are fragile — only an inch or so high, with the tiniest seedling leaf or two — but they're 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
Remember to harden off your seedlings once they're a few inches tall. This process of gradually introducing them to the outdoors makes 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
Place your transplants in the ground, then give them a generous drink of water — without drowning it. Surround them with mulch, marking where the plant is with a tag or stick so you can easily find it among the grass clippings, old leaves, or straw. If your yard is regularly visited by rabbits, squirrels, deer, or chipmunks, consider putting up chicken wire or other protective measures so your plants and veggies are less likely to get eaten before they thrive.
Protect Your Garden With Mulch
Finish your garden bed with compost and mulch. Compost enriches the soil so your garden can grow even better. It may help foster larger plants that bear more fruit and flowers. Mulch keeps your soil from drying out and controls weeds. 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 which spring flowers 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 Cottleville Garden Center, online, or on our mobile app. Let's get growing together.
