Mother and child gardening with tools

On those beautiful days, clean up the yard before everything blooms in earnest. Lawn care is often a priority, as well. Plan your garden to 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 Garden Center in Killeen can help you enjoy your spring activities to the fullest.

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 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. 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. 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
Growing season starts 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, plants, and flowers thrive in the Gulf region. 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 jalapeños, bell peppers, and more. Zucchini, cucumbers, squash, and pumpkins, which are direct sow only, will flourish. Tomato plants will yield thriving leaves and fruit, as they're tropical in origin and are happiest in the heat.

In balmy Zones 9 and 10, you can begin planning and planting indoors in January if you’d like. Zone 8 generally has a slightly later recommendation for indoor starts. Cruciferous veggies and garden favorites, like peppers, do well when started inside your home. Greens like spinach, artichokes, and fragrant herbs, including oregano, basil, and parsley, also don't mind an early beginning.

You can sow spring flower seeds and watch them mature under the grow lights, too. In this part of the country, your garden might still be growing if there's no reason to put it to bed — especially if it's close to the house or in a greenhouse. In that case, tend it as usual. Whatever you choose to grow, transplant them when the threat of frost is gone for the season.

Start Seeds Indoors
Save money when you 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 grow lights or a warming mat to go with your seed tray or planters. If you're planting a larger garden, use seed trays — like the ones you see sprouts in at your Killeen 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. 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 don't get all this pampering in nature when they volunteer and grow wherever they please, 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. Bring them inside or move them to a shady spot if they're looking rough. As always, make sure they're watered enough but not drowning. Whisk wilted plants inside and give them a good drink, making sure they're strong before setting them outdoors again.

Transplant Young Plants Into Their New Homes
You've raised your baby plants from seeds, watched them sprout, and carefully hardened them off to brave Mother Nature. By now, your plants have three or four true leaves — they'll look different from the miniature seedling leaves. When you're not expecting soaking rain, and the ground is warm, look into transplanting your small plants into their new outdoor home. "Transplant" means that you put these small plants straight into pots or garden soil. In cases where you direct sowed, 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 it all off with mulch and compost. Compost enriches the soil so your garden can grow even better. It may help foster larger plants that bear more fruit and flowers. Mulch controls weeds and keeps your soil from drying out. 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. 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 fertilizer, seeds, and soil you need in the aisles of your Killeen Garden Center, online, or on our mobile app. Let's get growing together.

Frequently Asked Questions About Gardening

What's my planting zone?

Check the USDA growing zone map, as planting zones have changed slightly over the years. Zones with higher numbers can plant earlier in the year. Increase your odds of successful gardening by choosing plants that are meant for your zone.

What does direct sow mean?

If the ground isn't frozen solid and the soil isn't cold, consider planting your fruit, veggie, or flower seeds directly into your garden. This is called the "direct sow" method. The time to plant will be after the threat of frost is gone for the season, as sprouts and seedlings can't weather those conditions. You can also start your seeds indoors if you'd like. Consult your seed envelope for when and how to sow seeds.

Do you carry organic plants and seeds?

Yes, we've got a variety of organic options, including organic fruit seeds and veggie seeds, and organic herb and flower seeds which are subject to availability. We carry the organic soil to plant it in as well as the organic fertilizer to feed it.

Do I have to harden off my seedlings before planting them outside?

Yes, if you raised plants indoors from seeds, harden them before you transplant them. Hardening allows your seedlings to adjust to the great outdoors and sun, rain, and temperature swings, making them more resilient against cold snaps. It slows their growth until they're strong and ready to take off during a spring warm front.

Can I strengthen my seedlings before planting them outdoors?

Get your sprouts used to breezy spring days and storms with a fan and keep fungus from growing in damp conditions. Set up an oscillating floor fan on low to mimic the wind. Just the gentlest breeze for several hours a day will do the trick. They'll gain strength even though you shouldn't see them moving. If you don't set up a fan, your seedlings may be more sensitive to strong winds. Try to plant between storms.

Should I use peat moss starters or coir starters?

Seed starters, full of nutrients in convenient pots or pellets, work for new and experienced gardeners alike. You don't have to use these starters if you're planting in soil, but you may want to. Starting seeds in peat pots works best for delicately rooted plants like cucumbers and eggplant, as well as flowers that need acidic soil. Some people prefer coir starters instead, as they have a neutral pH. Check what type of soil your plants need to help narrow it down, and chat with a garden center associate if you need more info.
