Frequently Asked Questions About Gardening

What planting zone am I in?

Check the USDA plant hardiness zone map, as planting zones have shifted 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 sowing mean?

If the soil is pliable and warm, consider planting your flower, fruit, or veggie seeds directly into your garden. This is called the "direct sow" method. Plant after the threat of frost is gone for the season, as seedlings and sprouts can't weather those conditions. You can also start your seeds indoors if you'd like. Consult your seed package for how and when to sow seeds.

Do you carry organic seeds and plants?

Yes, we've got a variety of organic options, including organic fruit seeds and veggie seeds, and organic herb and flower seeds that 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, for best results, if you raised plants indoors from seeds, harden them first before you transplant them. Hardening allows your seedlings to adjust to outdoor life, spring rains, 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 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. The stems and leaves will get used to blowing in the breeze and not snap when a gust comes through. If you don't set up a fan, your seedlings may be more sensitive to strong winds. Try to plant between storms.

What are seed tapes?

If you want more guidance in planting or are dealing with extremely tiny seeds, consider seed tapes. They're biodegradable pieces of paper with tiny seeds affixed at regular intervals. Just bury the tape and water as directed. If all goes well, you'll have perfectly spaced sprouts pop up soon.

It's time to start thinking of spring. We're here to help you prepare for warmer temperatures, fragrant breezes, 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 directly plant organic seeds into the earth.

Plant Hardiness Zones Explained
The first thing to know when planting veggies, spring flowers, 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 growing 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 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 seeds 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 flowers, vegetables, and plants 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 heat levels and colors, 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 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
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. Make sure you have a warm and sunny spot that gets at least 12 hours of light and good soil, a spray bottle of water, and patience. Then you have everything you need to try growing seeds. Early spring light isn't usually strong enough, so we recommend extra lighting to keep those seeds warm enough to germinate.

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 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
Harden your seedlings for strong plants. On days above 45 degrees, take your trays or pots of seedlings outside to slowly warm in the shade for a couple of hours, but bring them inside at night. A cloudy day will also work well. Gradually add an extra hour or two each day, incorporating a little sun to get your plants used to it. After a week or more of this, you can leave them out overnight if the temps stay above 50 degrees. Cover your plants if they're in the ground and a late-season frost sneaks back in.

Transplant Young Plants Into Their New Homes
Place your transplants in the ground, then give them a generous drink without overwatering. Blanket the surrounding area with mulch, marking where the plant is with a tag or stick so you can easily find it among the grass clippings, old leaves, or straw. Consider putting up chicken wire or other protective measures if rabbits, squirrels, deer, or chipmunks visit your yard regularly, as your sprouts may otherwise become a snack.

Protect Your Garden With Mulch
Finish your garden bed with mulch and compost. 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. 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
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 which spring flowers to plant when the weather warms. Shop for the fertilizer, soil, and seeds you need in the aisles of your Tomball Garden Center, online, or on our mobile app. Let's get growing together.
