Frequently Asked Questions About Gardening

Are there Spring Black Friday savings in the Garden Center?

The Home Depot Spring Black Friday Sale is a great time to save on lawn and garden, patio furniture, and outdoor power equipment. You can also get a jump on spring cleaning and DIY projects by snapping up low-priced tools. This spring sale for gardening only runs from April 9th through 22nd, so shop fast.

What's my planting zone?

Check the USDA zone map, as planting zones have changed slightly through the years. Zones with bigger numbers can plant earlier in the year. Up your chances of successful gardening by planting veggies, flowers, and trees that grow well in your zone.

Can I "direct sow" seeds in my garden?

If the ground isn't frozen, consider planting your fruit, flower, or veggie seeds right into your garden bed. This is called "direct sow." The time to plant will be after the possibility of frost is gone for the season, as seedlings and sprouts won't survive a frost. You can also start your seeds indoors if you'd like. Consult your seed package for how and when to sow your seeds.

How do I plant seeds?

The top source of information is the seed envelope each seed type arrived in. It's key to successfully growing fruit, vegetables, and spring flowers — outdoors or indoors. Requirements vary from one plant type to the next. Learn how to start seeds indoors if they require that. Your seed packet can tell you that, too. You'll be a pro at planting seeds in no time.

Do you carry organic herb plants?

We've got a variety of organic options, including organic fruit seeds and veggie seeds, as well as organic flower and organic herb seeds that are subject to availability. Check out our young organic plants, too. We carry the organic fertilizer to feed them and the organic soil to plant them in.

Should I harden off my seedlings before planting them outside?

Yes, for optimal results, if you raised seedlings indoors in your own plant nursery, harden them first before you transplant them. Hardening gets young plants used to the great outdoors and rain, sun, and temperature swings. It slows their growth until they're strong enough and ready for a growth spurt during a spring warm front. Hardening also makes your plants more resilient to a cold snap. Read your seed pouches or speak to a garden center associate for more info.

How do I prep for planting seeds or transplants outside?

Before you put your transplants in the ground, make sure that they will have the right amount of sunlight, warmth, and healthy soil. Check your seed envelope to see if they need shade, partial sun, or full sun, as well as when they should be planted. Space your plants as described on the seed packet for best results. You want your plant babies to have room to grow up big and strong.

Should I use peat moss starters or coir starters?

Seed starters, full of nutrients in convenient 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.

Celebrate Springtime Gardening
It's time to start thinking of spring. Sweep the gazebo and clean out the shed to prepare for warmer temperatures, sprouts poking up out of the ground, and fragrant breezes. Planting seeds indoors with grow lights means you'll be ready to transplant spring annuals and young veggie plants when the ground thaws and the frosts are through. You might even want to plant 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 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 zone map and learn when to plant flower bulbs and 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 6 garden can support plants listed as Zones 1–6. The timeframe to direct sow outdoors in your garden is often around a month later than the indoor start date. Always read your seed packet for details. If you start your seeds later than recommended, it's not ideal, but it will likely even out as time passes.

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

Much of West Virginia, Connecticut, New Jersey, southern New York state, Massachusetts, Ohio, and Pennsylvania 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, 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.

Plant Seeds In Your Garden With Direct Sow
Direct sow, or planting seeds directly into outdoor garden soil, is another way of gardening. If you prefer to go with the flow, follow the instructions on your seed package. Direct sow timeframes are later than indoor planting because the soil must be warm enough.

There's more variation with seed survival with direct sow. Your seedlings need to survive storms and hungry rodents, weather too much rain or sun, and obtain proper nutrition. Prepare to deal with whatever nature gives you. If you're lucky, you'll get strong sprouts that grow all spring.

Start Seeds Indoors
You can save money and gain the satisfaction of growing your garden from seeds by starting them indoors in your own plant nursery. We've got all the seed starter supplies you'll need. For best results, you'll want grow lights and heat mats to go with your nursery pots. If you're planting a larger garden, use seed trays — like the ones you see sprouts in at your nearest garden center — to plant tiny soil plugs with seedlings. You can also use pots with potting soil and seed starter mix.

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 plant tag or toothpick. 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.

Strengthen Your Sprouts
When your sprouts aren't ready to go outside, you can still prepare them for outdoor life. These micro-seedlings are fragile — only an inch or so high, with the tiniest seedling leaf or two — but they're 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 The Seedlings
Once your seedlings measure a few inches tall, start hardening them off. Gradually introducing them to the outdoors, making them stronger in the long run. Hardening means your sprouts may survive during a sudden cold snap.

Transplant Young Plants Into Their New Homes
In quality soil, dig a hole that's bigger than or the same size as your plant's dirt plug. Carefully remove your transplant without pulling on it, keeping it inside its clump of dirt. Place your transplant in the ground, and fill any extra space with nutrient-rich fertilizer and topsoil, then be sure to water it. Never apply more fertilizer than recommended, as adding more could burn the plant. Consider putting up garden fencing or other protective measures if squirrels, rabbits, deer, or chipmunks visit your yard regularly, as your sprouts may otherwise get eaten.

Enrich Your Garden With Mulch and Compost
Finish it all off with mulch and compost. Mulch controls weeds and keeps your soil from drying out. Compost enriches the soil so your garden can grow even better. It may help foster stronger plants that bear more fruit and flowers. Mulch and compost can be purchased in-store, or you can learn how to compost DIY-style. The next time you're looking for "mulch near me," stop by the Garden Center to get the correct amount.

Greet the Spring
Don't miss a minute of growing season. Plan your garden and landscaping, prepare to fertilize your lawn, and browse your nearest nursery to find inspiration on which spring flowers to plant when the weather warms. For those without lawns, consider adding an outdoor rug, a pellet grill, or artificial grass to your patio or balcony. Shop for the seeds, soil, and fertilizer you need in the aisles of your Union - Rt 22 Garden Center, online, or on our mobile app. Let's get growing together.
