Frequently Asked Questions About Gardening
How do I check my planting zone?
Check the USDA 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.
When can I plant seeds outside?
If the soil is pliable and warm, consider planting your fruit, flower, or veggie 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 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?
We offer many organic gardening options, including organic veggie seeds and fruit seeds, as well as organic herb and flower seeds that are subject to availability. We carry the organic soil to plant them in as well as the organic fertilizer to feed your plants.
Do I have to harden off my seedlings before planting them outside?
Yes, if you raised plants indoors from seeds in your own plant nursery, 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.
What do I do before planting seeds or transplants outside?
Before you plant, make sure that your plant will have the right amount of sun, the soil is healthy, and it's warm enough outside. Check your seed envelope to see if it likes partial sun, shade, or full sun, as well as what time of year it should be planted. Space your plants as described 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 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.
The Home Depot Garden Center at Maryville
Set Up For Springtime
On beautiful spring days, tidy the yard before everything blooms in earnest. Lawn care is often a priority as well. Don't forget to clean out the shed and sweep the gazebo in preparation for spring, too. No matter what outdoor projects you choose to tackle and which plants you need, search for your local plant nursery and find that The Home Depot Garden Center in Maryville can help you enjoy your spring activities to the fullest.
Plant Hardiness Zones Explained
The first thing to know when planting spring flowers, vegetables, 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 plant bell pepper seedlings 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 7 garden can support plants listed as Zones 1–7. 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 seeds later than recommended, it's not ideal, but it will even out as time passes.
Gardening in Your Growing Zone
Kentucky, Tennessee, Virginia, and West Virginia are in Zones 6–8. Cruciferous veggies and certain herbs are ready to grow when you're ready to plant. This includes kale, cabbage, and broccoli. Greens like spinach and artichokes, early-blooming annuals like marigolds, and fragrant herbs, including oregano, basil, and parsley, also don't mind an early beginning. Even in the highest peaks of West Virginia in Zone 5b, traditional garden vegetables like peppers of all kinds, cucumbers, and tomatoes are fine with an early spring or late winter start indoors under the grow lights.
Look up the date of your last predicted frost, then count backward 6 to 8 weeks. That's when you should sow your seeds indoors. The idea is to have strong baby plants that are ready for transplant at the same time the ground is warm enough. Do your best and enjoy the process — watching your plants grow, bloom, and put out tiny veggies that'll grow to harvest size is part of the fun.
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.
Prepare to deal with whatever hand nature deals you: Be ready for none of your seeds to sprout, all of them to come up, and anything in between. Your seedlings will need to survive wind, rain, and sudden cold snaps, as well as insects and animals that crave tender greens. But if you're lucky, you'll get strong sprouts that are ready to grow all spring.
Start Seeds Indoors
If you're eager to get growing or would like more control in the care and feeding of seedlings, 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 cozy with heat mats and grow lights, water them carefully with a mister 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
Place your transplants in the ground, then give them a generous drink without overwatering. Surround them with mulch, marking where the plant is with a stick or tag so you can easily find it among the grass clippings, old leaves, or straw. If your yard is regularly visited by rodents or deer, 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 off your garden with mulch and compost. Mulch keeps your soil from drying out and controls weeds. Compost enriches the soil so your garden can grow even better. It may help foster larger plants that bear more fruit and flowers. Mulch and compost can be purchased in-store or created at home. 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 which spring flowers to plant when the weather warms. For those without lawns, consider adding artificial grass, a pellet grill, or an outdoor rug to your patio or balcony. Shop for the soil, seeds, and fertilizer you need in the aisles of your Maryville Garden Center, online, or on our mobile app. Let's get growing together.
