Frequently Asked Questions About Gardening
How do I check my planting zone?
Check the USDA plant hardiness zone map, as planting zones have changed slightly over the years. Planting zones with higher numbers can plant earlier in the year. Choose plants that are meant for your zone and increase your odds of successful gardening.
Can I plant seeds directly in the ground?
If the ground isn't frozen solid and the soil isn't cold, consider planting your veggie, flower, or fruit 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.
Do you carry organic plants and seeds?
We offer many organic gardening options, including organic fruit seeds and veggie seeds, as well as organic herb and flower seeds that are subject to availability. We also carry the organic fertilizer to feed your plants and the organic soil to plant them in.
Should I harden off my seedlings before planting them outside?
Yes, for best results, if you raised plants indoors from seeds in your own plant nursery, harden them before you transplant them. Hardening is the process of getting them used to outdoor life, spring rains, and temperature swings. 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. Read your seed packets or speak to a garden center associate for more information.
What do I do before planting transplants or seeds outside?
Before you plant, make sure that your plant will have the right amount of sun, it's warm enough outside, and the soil is healthy. Check your seed packet to see if it likes full sun, shade, or partial sun, as well as what time of year it should be planted. Space your plants as described on the seed package for best results so your plant babies have room to grow big and strong.
Should I use peat moss starters or coir starters?
Seed starters, full of nutrients in pellets or pots, work for new and experienced gardeners. 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.

Set Up For Springtime
It's time to start thinking of spring. Clean the shed and sweep out the gazebo to prepare for fragrant breezes, warmer temperatures, and sprouts poking up out of the ground. Planting seeds indoors means you'll be ready to transplant young veggie plants and spring annuals when the ground thaws and the frosts are through. You might even want to sow organic seeds directly into the earth. What better way to start than by exploring your favorite local plant nursery?
Plant Hardiness Zones Explained
The first thing to learn when planting vegetables, 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. The plants that'll thrive in your area are in your zone — plus all the zones numbered less than that. 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. 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 region ranges from 7–9, with higher elevations in Zones 5 and 6. You'll find fertile land in some places, but deserts and mountains with harsher conditions elsewhere. What you can grow and when will vary considerably depending on where you live. In Zones 5 and 6, the outdoor growing season doesn't begin here until mid-March or even April, although you can start some veggies by seed halfway through February. Warmer Zones 7–9 can plant earlier, but if you're in the desert, you'll likely want to investigate indoor gardening in a sunroom or porch.
Utilize greenhouses to grow herbs and vegetables. Native plants like succulents, cacti, and other hardy desert shrubs will grow outside with ease. Other beloved garden vegetables love the heat, like tomatoes, squash, peppers, and cucumbers. If you start them indoors and carefully introduce them outdoors in the shade, you can enjoy raising vegetables even in a dry climate. Heat-resistant spring flower seeds, whether they're perennials or annuals, can also often get an indoor start.
Plant Seeds Outside With Direct Sow
Planting seeds into your garden soil, or using the direct sow method, is an alternative option. There's less planning and tending than growing indoors. If you like to go with the flow, follow the instructions on your seed pack and try it.
Your seeds might get washed away or struggle to grow, or critters or bugs might eat the sprouts. But if you're really fortunate, you might get a strong sprout from each place you sowed seeds, perfectly spaced and ready to grow all spring. The reality of your garden will usually be somewhere in between, and spreading out tiny sprouts throughout the soil isn't so bad. You know those sprouts are hardy, although there are no guarantees.
Start Seeds Indoors
If you'd like more control over your seedlings' journey or you're eager to get growing, start your seeds indoors in your own plant nursery. In general, you can plant seeds indoors about a month before you can do it outside. Like direct sow, you push the seeds into the soil as directed on the seed packet, but that's where the similarities end.
You're responsible for giving them quality substitutes for rain and sunlight. Keep your seeds warm with warming mats and grow lights, water them carefully with a spray bottle or watering can, then thin them as they germinate in groups of three. Give them a boost with a gently blowing fan as they lengthen into sprouts if you'd like. Harden them off to get them used to outdoor conditions, then transplant them into your garden when they're big enough.
Transplant Young Plants Into Their New Homes
Carefully take your seedling out of the container. Turn it upside-down or sideways and gently squeeze the plastic to break the seal. If your transplant grew in the garden, leave plenty of room around the stem and dig deeper than you think with your garden trowel. You don't want to damage the roots. Put the plant in the new hole and ensure it's even with the surrounding soil.
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. 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
Don't miss a minute of growing season. Plan your garden and landscaping, prepare to fertilize your lawn, and browse The Home Depot nursery to find inspiration on what to plant when the weather warms. For those without lawns, consider adding artificial grass or an outdoor rug to your outdoor space. Shop for the seeds, soil, and fertilizer you need in the aisles of your 21St South Garden Center, online, or on our mobile app. Let's get growing together.
