Celebrate Springtime Gardening
It's time to start thinking of spring. Sweep the gazebo and clean out the shed 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 annuals when the frosts are through and the ground thaws. You might even want to sow seeds directly into the earth. What better way to start than by exploring your favorite local plant nursery, The Garden Center in N Thornton?

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 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 7 garden can support plants listed as Zones 1–7. 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 a little later than recommended, it's not ideal, but it will 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 can have extreme conditions, so consider indoor gardening as a strong supplement to growing outdoors if possible.

In the desert, native plants like succulents, cacti, and other hardy desert shrubs will easily grow outside. 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. Compatible spring flower seeds, whether they're annuals or perennials, can also often get an indoor start.

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 life.

Check out cruciferous veggies and certain herbs if you're ready to get planting. This includes broccoli, kale, and cabbage. Greens like artichokes, spinach, and fragrant herbs, including basil, parsley, and oregano, 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 into your garden soil, or using the direct sow method, is an alternative option. There's less tending and planning than growing indoors. If you like to go with the flow, follow the instructions on your seed pack and try it out.

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 wind, rain, and sudden cold temperatures, as well as critters and bugs that crave tender greens. 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 in your own plant nursery. 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 warm with heat 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
By now, your plants have three or four true leaves — they'll look different from the miniature seedling leaves. When the ground is warm, and you're not expecting soaking rain, 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 off your garden with compost and mulch. Mulch keeps your soil from drying out and controls weeds. Compost enriches the soil so your garden can grow even better. It may help foster stronger and larger 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.

Greet the Spring
Late winter into early spring is an exciting time in the world of gardening. Prepare to fertilize your lawn, plan your garden and landscaping, and browse The Home Depot nursery to find inspiration on what to plant when the weather warms. For those without lawns, consider adding artificial grass or a pellet grill to your outdoor space. Shop for the seeds, fertilizer, and soil you need in the aisles of your N Thornton Garden Center, online, or on our mobile app. Let's get growing together.
