Garden Center at Tucson / Oracle #414

Set Up For Springtime
It's time to start thinking of spring. Clean the shed and sweep out the gazebo to prepare for fragrant breezes, warmer temperatures, and sprouts poking up out of the ground. 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 Tucson / Oracle?

Plant Hardiness Zones Explained
The first thing you should know when planting vegetables, 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 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 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. Be sure to read your seed packet for details. If you start plants later than recommended, it's not ideal, but it should 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 mountains and deserts can have extreme conditions, so consider indoor gardening as a 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. Heat-resistant spring flower seeds, whether they're perennials or annuals, 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, waiting until the frost has passed will 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 kale, broccoli, and cabbage. Greens like spinach, artichokes, 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.

Start Seeds Indoors
Grow your garden from seeds by starting them indoors in your own plant nursery. We've got all the seed starter supplies you'll need. For best results, you'll want grow lights or a warming mat to go with your seed tray or plant pots. If you're planting a larger garden, use seed trays — like the ones you see sprouts in at your Tucson / Oracle Garden Center — to stay organized and plant tiny soil plugs when the time comes. You can also use pots with seed starter mix and potting soil.

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 plant tag or toothpick. That way, you'll know where your seeds should pop up, and you can be sure they're not weeds. Otherwise, it'll be a surprise when the sprouts push out of the soil.

Sprouts
Prepare your seed sprouts for outdoor life while they're still indoors. These inch-tall micro-seedlings are fragile but resilient. Seedlings don't get all this pampering in nature when they volunteer and grow wherever, 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 fan on low to mimic the wind and strengthen their stems.

Harden Your Seedlings
When you're hardening your sprouts and gradually introducing them to the outdoors, be flexible. Keep an eye on your baby plants. If they're looking rough, don't push them. It’s ok to roll back a step or two if need be: Bring them inside overnight or put them in shady places instead of direct sun. As always, make sure they're watered enough. Whisk wilted plants inside and give them a good drink, making sure they're healthy before returning them outdoors.

Transplant Young Plants Into Their New Homes
When your plants have three or four true leaves — different from miniature seedling leaves — 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 great, 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 it all off with compost and mulch. Compost enriches the soil so your garden can grow even better. It may help foster larger and stronger plants that bear more fruit and flowers. Mulch controls weeds and keeps the soil moist. 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
Early spring is an exciting time in the world of gardening. Plan your garden and landscaping, prepare to fertilize your lawn, and browse The Home Depot nursery to find inspiration on what to plant when the weather warms. For those without lawns, consider adding an outdoor rug, artificial grass, or a pellet grill to your balcony or patio. Shop for the fertilizer, soil, and seeds you need in the aisles of your Tucson / Oracle Garden Center, online, or on our mobile app. Let's get growing together.
