Frequently Asked Questions About Gardening

What's my planting zone?

Check the USDA planting zone map, as planting zones have shifted over the years. Planting 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's direct sow in gardening?

If the soil is pliable and warm, 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 flower seeds?

Follow the advice on your seed envelope. It'll tell you when to start them indoors and when to direct sow. Generally, you'll add 3 to 5 seeds per planting hole, then press them into the soil as directed. Mark where you planted them with a wooden craft stick, twig, or flag so you don't mistake them for weeds later.

Do I have to harden off my seedlings before planting them outside?

Yes, for best results, if you raised plants indoors from seeds, harden them first 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 mounding a volcano of dirt around your plant, and don't pack 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, you'll have perfectly spaced sprouts pop up soon.

It's time to start thinking of spring. We're here to help you prepare for fragrant breezes, sprouts poking up, and warmer temperatures. Planting seeds indoors means you'll be ready to transplant spring flowers and young veggie plants when the frosts are through and the ground thaws. You might even want to directly plant seeds into the earth.

Plant Hardiness Zones Explained
The first thing to 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 plant hardiness 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 9 garden can support plants listed as Zones 1–9. The timeframe to direct sow outdoors in your garden is often around a month later than the indoor start date. Always read your seed packet for details. If you start plants a little 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 thrive in this region, and most of them can get an early start indoors before spring really moves in.

Also, check out certain herbs and cruciferous veggies if you’re ready to get planting. This includes broccoli, cabbage, and kale. 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.

Plant Seeds Outside With Direct Sow
Planting seeds with the direct sow method, right into the soil, is another option. There's less tending and planning than growing indoors. If you like to go with the flow, follow the instructions on your seed package and give it a try.

Prepare to deal with whatever hand nature deals you: You might have no germinating seeds. A critter could eat the tender seedlings. All the seeds you plant in each hole may sprout, so you'll need to spread them out later or choose the most robust sprouts to survive in a process called thinning. Insects or garden pests might make a meal out of your seedlings before they take off. But if you're lucky, you'll get strong sprouts that are ready to grow all spring.

Start Seeds Indoors
If you'd like more control over your seedlings' journey or you're eager to get growing, start your seeds indoors instead. In general, you can plant seeds indoors about a month before you can do it outside. Like direct sow, you push the seeds into the soil as directed on the seed packet, but that's where the similarities end.

You're responsible for giving them quality substitutes for sunlight and rain. Keep your seeds cozy with warming mats and grow lights, water them carefully with a spray bottle or watering can, then thin them as they germinate in groups of three. Give them a boost with a gently blowing fan as they lengthen into sprouts if you'd like. Harden them off to get them used to outdoor conditions, then transplant them into your garden when they're big enough.

Transplant Young Plants Into Their New Homes
Place your transplants in the ground, then water them well. 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 deer or rodents, 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 flower bed with mulch and compost. Compost enriches the soil so your garden can grow even better. It may help foster stronger plants that bear more flowers and fruit. Mulch controls weeds and keeps your soil from drying out. Compost and mulch 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. 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 Collinsville, IL Garden Center, online, or on our mobile app. Let's get growing together.
