It's time to start thinking of spring. We're here to help you prepare for sprouts poking up, fragrant breezes, 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 to 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. You'll have good results with plants that have your zone number or less. 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. Always 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
This area is in growing Zones 8 or 9, but it’s desert, so utilize greenhouses to grow vegetables and herbs. Native plants like cacti, succulents, and other hardy desert shrubs will easily grow outside. Other beloved garden vegetables love the heat, like tomatoes, peppers, cucumbers, and squash. 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.

An indoor garden of greenery is also lovely, so create an oasis inside your home. A covered porch or sunroom is a great place to encourage plant growth, especially with pots and plant stands of all sizes. Your spring flower seed choices, whether they're perennials or annuals, can also often get an indoor start.

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

Sprouts
When your seeds have sprouted but aren't ready to go outside yet, you can still prepare them for outdoor life. These micro-seedlings are fragile — only an inch or so high, with the tiniest seedling leaf or two — but they're resilient. Seedlings certainly don't get all this pampering in nature, 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
Harden off your seedlings once they're a few inches tall. 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 true leaves — different from mini 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. Only apply as much as recommended, as you could burn and kill the plant instead of helping it along.

Protect Your Garden With Mulch
Finish off your garden 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 keeps your soil from drying out and controls weeds. Mulch and compost 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.
