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 with grow lights 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 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 by climate. Find your zone on the USDA planting 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. Be sure to read your seed packet for details. If you start them later than recommended, it's not ideal, but it should 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 certain herbs and cruciferous veggies if you’re ready to get planting. This includes kale, cabbage, and broccoli. 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.

Plant Seeds Outside With Direct Sow
Planting seeds into your garden soil, or using the direct sow method, is an alternative option. It doesn't give you as much organized planning in terms of space and reliability as starting indoors. However, if you like to go with the flow, follow the instructions on your seed packet and try it out.

Prepare to deal with whatever hand nature deals you: You might have no seeds that germinate. A critter could snack on the seedlings. All the seeds you plant in each hole may sprout, so you'll need to thin them out by only leaving the most robust sprouts. Garden pests or insects 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're eager to get growing or would like more control in the care and feeding of seedlings, 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 rain and sunlight. 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
When your plants have three or four true leaves — different from mini seedling leaves – it's time to 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 and kill the plant instead of helping it along.

Protect Your Garden With Mulch
Finish off your garden with mulch and compost. Compost enriches the soil so your garden can grow even better. It may help foster stronger plants that bear more fruit and flowers. 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 right amount.
