Garden Center at Tustin #603

On those beautiful days, clean up the yard before everything blooms in earnest. Many people feel inspired to refresh their outdoor space for entertaining, as well. Planning your garden lets you make the most of your time and space. You can also add beauty and interest with hardscaping, stonework, and water features. No matter what outdoor projects you choose to tackle, The Home Depot Tustin Garden Center can help you enjoy your spring activities to the fullest.

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 into blocks by climate. Find your zone on the USDA plant hardiness 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. 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 6 garden can support plants listed as Zones 1–6. 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 plants later than recommended, it's not ideal, but it will likely even out as time passes.

Gardening in Your Growing Zone
The southernmost part of California is primarily in Zones 9 and 10, with small areas of 6–8 sprinkled in near Palm Springs and San Bernadino. A temperate Mediterranean climate on the coast means it’s usually lovely gardening weather and excellent for growing. Areas in the mountains and desert are more challenging to grow vegetables in, but indoor gardening is an excellent workaround.

For more temperate areas, find your planting zone and prepare to get planting. Growing season begins early and ends late in this part of the country. The climate and weather make it easy to get and keep a beautiful garden going. A wide variety of vegetables, flowers, and plants thrive in southern California. You can even grow citrus trees for fresh fruit when you plant somewhere with good soil drainage. You’ll have excellent results with peppers of all colors and heat levels, including bell peppers, jalapeños, and more. Zucchini, cucumbers, squash, and pumpkins, which are direct sow only, will flourish. Planting tomatoes will yield thriving leaves and fruit, as they’re tropical in origin and are happiest in the heat.

In the desert, native plants like cacti, succulents, and other hardy desert shrubs will easily grow outside. Other beloved garden vegetables love the heat. 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 are sensitive to that much heat and sun, so research to find which varieties can handle the weather before planting outdoors.

Start Seeds Indoors
You can save money and gain the satisfaction of growing your garden from seeds by starting them indoors. We've got all the seed starter supplies you'll need. For best results, you'll want warming lights or a warming mat to go with your seed tray or planter pots. If you're planting a larger garden, use seed trays — like the ones you see sprouts in at your Tustin Garden Center — to make it easy to stay organized and plant tiny soil plugs later. You can also use pots with potting soil and seed starter mix.

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. 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 certainly 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 floor fan on low to mimic the wind and strengthen their stems.

Harden Your Seedlings
Once your seedlings have sprouted and are a few inches tall, start hardening them off. This is a process of gradually introducing them to the outdoors, making them stronger in the long run. Hardening means you're less likely to lose your growing garden during a sudden cold snap.

Transplant Young Plants Into Their New Homes
When your plants have three or four real leaves — different from mini seedling leaves – it's time to transplant them. In quality soil, dig a hole that's 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 room with nutrient-rich topsoil. Apply any fertilizer as directed on the package, either on top of the soil after it's planted or in the hole. Only apply as much as recommended, as you could burn the plant and kill it instead of helping it.

Protect Your Garden With Mulch
Finish your flower bed with mulch and compost. 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 flowers and fruit. 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. Don't miss a minute of growing season. Plan your garden and landscaping, prepare to fertilize your lawn, and browse our garden center pages to find inspiration on which spring flowers to plant when the weather warms. Shop for the soil, seeds, and fertilizer you need in the aisles of your Tustin Garden Center, online, or on our mobile app. Let's get growing together.
