Frequently Asked Questions About Gardening

How do I check my USDA 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. 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 warm and pliable, 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 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?

We offer many organic gardening options, including organic fruit seeds and veggie seeds, as well as organic flower and herb 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 the great outdoors, 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 it's warm enough outside, your plant will have the right amount of sun, and the soil is healthy. Check your seed package 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 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 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.

Celebrate Springtime Gardening
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 with grow lights 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 you should 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 planting 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 5 garden can support plants listed as Zones 1–5. 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 them later than recommended, it's not ideal, but it will 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 porch or sunroom.

Utilize greenhouses to grow herbs and vegetables. Native plants like cacti, succulents, and other hardy desert shrubs will grow outside with ease. Other beloved garden vegetables love the heat, like squash, tomatoes, 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. However, many spring flowers are sensitive to that much sun and heat, so research to find varieties that can handle the weather before planting outdoors.

Plant Seeds Outside With Direct Sow
Planting seeds into your garden soil, or using the direct sow method, is an alternative option. It doesn't give you as much organized planning in terms of space and reliability as starting indoors. However, 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: You could have no seeds that germinate. A critter may snack on the seedlings. All the seeds you plant in each hole may sprout, so you'll need to choose the most robust sprouts to survive in a process called thinning. Heavy rain might wash away the seeds. 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 sun. Keep your seeds cozy with heat 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
Place your transplants in the ground, then water them well. 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 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 planting by following it with compost and mulch. 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 the soil moist. Compost and mulch 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 what 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, fertilizer, and seeds you need in the aisles of your The Home Depot Pro Garden Center, online, or on our mobile app. Let's get growing together.
