Frequently Asked Questions About Gardening

What planting zone am I in?

Check the USDA zone map, as planting zones have shifted slightly through 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 gardening success.

When can I plant seeds outside in the spring?

If the soil isn't frozen or cold, consider planting your flower, veggie, 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 package for how and when to sow seeds.

Do you carry organic plants and seeds?

Yes, we've got a variety of organic options, including organic fruit seeds and veggie seeds, as well as organic flower and herb 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, 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 the great outdoors. 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 info on caring for your seedlings.

How do I prep for planting seeds or transplants outside?

Before you plant, make sure that it's warm enough outside, the soil is healthy, and your plant will have the right amount of sun. Check your seed package 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 for best results so your plant babies have room to grow big and strong.

What are seed tapes?

If you're dealing with extremely tiny seeds or want more guidance in planting, 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.

Celebrate Springtime Gardening
It's time to start thinking of spring. Sweep the gazebo and clean out the shed to prepare for fragrant breezes, sprouts poking up, and warmer temperatures. 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 plant organic seeds directly into the earth. What better way to start than by exploring your favorite local plant nursery, The Garden Center in Thompson?

Plant Hardiness Zones Explained
The first thing to know 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. For best results, choose plants in your zone number or less. In other words, a Zone 7 garden can support plants listed as Zones 1–7. You can plant seeds indoors roughly a month before you can plant them outside, known as direct sow. Always read your seed packet for details. If you start seeds a little later than recommended, it's not ideal, but it will even out as time passes.

Gardening in Your Growing Zone
In Zone 5, which includes parts of Pennsylvania as well as upstate New York, Vermont, New Hampshire, and southern Maine, your best bets for veggies will be root vegetables like beets and carrots, leafy greens including lettuce, and cruciferous veggies like broccoli and kale. You can try squash, but prepare for additional warming upkeep when late frost is forecast. Target planting dates are roughly mid-March through May 1st, depending on whether you're directly sowing them into your garden or starting your seeds indoors.

Much of Ohio, Pennsylvania, West Virginia, New Jersey, Connecticut, southern New York state, and Massachusetts are in Zone 6, so planting can begin earlier there than farther north. Parts of Virginia are even warmer, coming in at Zone 7. The outdoor growing season doesn't begin until mid-March or even April, although you can plant some veggie seeds halfway through February. Tomatoes, peppers, cucumbers, squash, onions, and other classic garden crops will do well in this region, and most of them can get an early start indoors before spring really moves in.

Start Seeds Indoors
Grow your garden from seeds by starting them indoors in your own seedling garden. We've got all the seed starter supplies you'll need. Veteran planters and new gardeners alike should disinfect seed trays with a watered-down bleach solution before reusing them each year. When your trays or pots are prepared, plant your seeds. As for the soil, check to see if yours needs nutrient balancing. Choose fertilizers that match what you're growing. It'll help give your plants everything they need to grow big and strong.

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. That way, you'll know where your seeds should pop up. 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 fan on low to mimic the wind and strengthen their stems.

Harden Your Seedlings
Make sure to harden your seedlings for best results when they're grown. On days above 45 degrees, take your pots or trays of seedlings outside to slowly warm in the shade for two hours, but bring them inside at night. Cloudy days are fine, but no direct sunlight or harsh nighttime chills yet. After a week or more of this, you can leave them out overnight if the temps stay at 50 degrees or above at night. Cover your plants if they're in the ground when a late-season frost sneaks back in.

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 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 deer or rodents visit your yard regularly, as your sprouts may otherwise become a snack.

Protect Your Garden With Mulch
Finish off your garden with compost and mulch. Mulch controls weeds and keeps the soil moist. Compost enriches the soil so your garden can grow even better. It may help foster stronger and larger plants that bear more fruit and flowers. 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
Late winter into early spring is an exciting time in the world of gardening. Prepare to fertilize your lawn, plan your garden and landscaping, 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 Thompson Garden Center, online, or on our mobile app. Let's get growing together.
