It's time to start thinking of spring. We're here to help you prepare for warmer temperatures, and sprouts poking up, and fragrant breezes. Planting seeds indoors near a sunny window means you'll be ready to transplant young veggie plants and spring annuals when the ground thaws and the frosts are through. You might even want to directly plant organic 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 into blocks by climate. Find your zone on the USDA 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. The plants that'll thrive in your area are in your zone, and all the zones numbered less than that. In other words, a Zone 5 garden can support plants listed as Zones 1–5. 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 them a little later than recommended, it's not ideal, but it will likely even out as time passes.

Gardening in Your Growing Zone
The diverse topography of this area means planting times vary widely. Desert areas are in Zones 7-10, depending on location, and areas with more elevation are in chillier Zones 4–6. Both deserts and mountains are susceptible to extreme conditions, so consider indoor gardening as a supplement to growing outdoors if possible.

In the desert, native plants like cacti, succulents, and other hardy desert shrubs will grow outside with ease. Other beloved garden vegetables love the heat, like nightshades. If you start them indoors and carefully introduce them outdoors in the shade, you can enjoy raising vegetables even in a dry climate. However, many flowers, both annuals and perennials, are sensitive to that much heat and sun, so research to find varieties that can handle the weather before planting outdoors.

Colder regions in Zones 6–8 should wait a little longer to plant, and all these zones need to wait an additional month before planting seeds outdoors rather than indoors. Mountainous regions in Zones 3 to 5 will have the shortest growing season, with seed starters going in later in the spring. Although the weather may vary, wait until the frost has passed to give your seeds the best chance at a healthy and hearty life.

Check out certain herbs and cruciferous veggies if you’re ready to get planting. This includes cabbage, broccoli, and kale. Greens like artichokes, spinach, and fragrant herbs, including oregano, basil, and parsley, also don't mind an early beginning. In Zones 4–6, traditional garden vegetables like peppers of all kinds, cucumbers, and tomatoes are fine with an early spring or late winter start indoors under the grow lights.

Plant Seeds Outside With Direct Sow
Planting seeds with the direct sow method, right into the soil, is another 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 give it a try.

Prepare to deal with whatever hand nature deals you: Be ready for all your seeds to sprout, none of them to come up, and anything in between. Your seedlings will need to survive rain, wind, rodents and bugs that crave tender greens, and sudden cold temperatures. 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 warm with heating mats and grow lights, water them carefully with a mister 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 give them a generous drink of water. Blanket the surrounding ground 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 off your garden with compost and mulch. 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 fruit and flowers. 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 right amount.
