Mother and child gardening with tools

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. Remember to measure your garden so you can find fresh mulch near you as soon as it's available. No matter what outdoor projects you choose to tackle, The Home Depot Westheimer Garden Center can help you enjoy your spring activities to the fullest.

Plant Hardiness Zones Explained
The first thing you should know when planting veggies, 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 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 9 garden can support plants listed as Zones 1–9. The timeframe to direct sow outdoors in your garden is often around a month later than the indoor start date. Always read your seed packet for details. If you start them a little later than recommended, it's not ideal, but it will likely even out as time passes.

Gardening in Your Growing Zone
Growing season starts early and ends late in this part of the country. The weather and climate make it easy to get and keep a beautiful garden. A wide variety of plants, vegetables, and flowers thrive in the Gulf region. If you've got good soil drainage, you can even grow citrus trees. You'll have excellent results with peppers of all colors and heat levels, including bell peppers, jalapeños, and more. Cucumbers, zucchini, squash, and pumpkins, which are direct sow only, will flourish. Tomato plants will yield thriving fruit and leaves, as they're tropical in origin and love 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 basil, parsley, and oregano, 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
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 Westheimer 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. 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
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, 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
Place your transplants in the ground, then water them well. Surround them with mulch, marking where the plant is with a stick so you can easily find it among the grass clippings, old leaves, or straw. If your yard is regularly visited by deer or rodents, consider putting up chicken wire or other protective measures so your plants and veggies are less likely to get eaten before they thrive.

Protect Your Garden With Mulch
Finish your flower bed 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 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.

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. Prepare to fertilize your lawn, plan your garden and landscaping, and browse our garden center pages to find inspiration on what to plant when the weather warms. Shop for the fertilizer, seeds, and soil you need in the aisles of your Westheimer Garden Center, online, or on our mobile app. Let's get growing together.

Frequently Asked Questions About Gardening

How do I check my planting zone?

Check the USDA planting zone map, as planting zones have shifted over the years. Planting 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.

Can I plant seeds directly in the ground?

If the soil is warm and pliable, 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 packet for how and when to sow seeds.

How do I plant flower seeds?

Follow the advice on your seed package. It'll tell you when to start them indoors and when to plant them outside. Generally, you'll add three to five seeds per planting hole, then press them into the soil at the correct depth. Mark where you buried the seeds with a toothpick, twig, or flag so you don't mistake them for weeds later.

Should I harden off my seedlings before planting them outside?

Yes, for best results, if you raised plants indoors from seeds, harden them first before you transplant them. Hardening is the process of getting them used to outdoor life and the fluctuating spring weather. It slows their growth until they're strong and ready to take off during a spring warm front. Hardening also makes your plants more resilient to a sudden cold snap.

How do I strengthen my seedlings before planting them outdoors?

Get your sprouts used to storms and breezy spring days 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. This makes them stronger against wind gusts. 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 pellets or pots, 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 carrots and beets, as well as flowers that require an acidic pH. 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.
