Mother and child gardening with tools

On those beautiful days, clean up the yard before everything blooms in earnest. Many people feel inspired to refresh their outdoor space for entertaining, as well. Plan your garden to make the most of your time and space. Remember to measure your garden so you can find fresh mulch near you as soon as it's available. No matter what outdoor projects you choose to tackle, The Home Depot Garden Center in Riverhead can help you enjoy your spring activities to the fullest.

Plant Hardiness Zones Explained
The first thing to learn when planting veggies, spring flowers, 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 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, and all the zones numbered less than that. In other words, a Zone 6 garden can support plants listed as Zones 1–6. You can plant seeds indoors roughly a month before you can plant them outside, or direct sow. Always read your seed packet for details. If you start seeds later than recommended, it's not ideal, but it should 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 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 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
Save money and gain the satisfaction of growing your garden from seeds by starting them indoors. We've got all the seed starter supplies you'll need. For best results, you'll want warming lights or a warming mat to go with your seed tray or planters. If you're planting a larger garden, use seed trays — like the ones you see sprouts in at your Riverhead Garden Center — to make it easy to stay organized and plant tiny soil plugs later. You can also use pots with seed starter mix and potting soil.

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. 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 certainly don't get all this pampering in nature when they volunteer and grow wherever they please, 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 floor fan on low to mimic the wind and strengthen their stems.

Harden Your Seedlings
When you're hardening your sprouts and gradually introducing them to the outdoors, be flexible. Keep an eye on your baby plants. If they're looking rough, don't push them. It’s ok to roll back a step or two if need be: Bring them inside overnight or put them in shady places instead of direct sun. As always, make sure they're watered enough but not drowning. Whisk wilted plants inside and give them a good drink, making sure they're healthy before returning them outdoors.

Transplant Young Plants Into Their New Homes
Carefully take your seedling out of the container. Turn it sideways or upside-down 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 root ball. Put the plant in the hole and ensure it's even with the surrounding soil.

Protect Your Garden With Mulch
Finish your planting by following it with mulch and compost. Compost enriches the soil so your garden can grow even better. It may help foster stronger plants that bear more fruit and flowers. Mulch keeps your soil from drying out and controls weeds. 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. Don't miss a minute of growing season. Prepare to fertilize your lawn, plan your garden and landscaping, and browse our garden center pages to find inspiration on what to plant when the weather warms. Shop for the fertilizer, soil, and seeds you need in the aisles of your Riverhead Garden Center, online, or on our mobile app. Let's get growing together.

Frequently Asked Questions About Gardening

Which planting zone am I in?

Check the USDA plant hardiness zone map, as planting zones have shifted slightly through the years. Planting zones with higher numbers can plant earlier in the year. Increase your odds of successful gardening by choosing plants that are meant for your zone.

What's direct sow?

If the soil isn't frozen or cold, consider planting your flower, fruit, or vegetable 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.

How do I plant veggie seeds?

Follow the directions on your seed packet. It'll tell you when to start them indoors and when to plant them outside. Generally, you'll add 3 to 5 seeds per planting hole, then press them into the soil at the correct depth. Mark where you planted them with a wooden craft stick, flag, or twig so you don't mistake them for weeds later.

Should I harden off my seedlings before planting them outside?

Yes, if you raised plants indoors from seeds, harden them before you transplant them. Hardening is the process of getting them used to outdoor life and the fluctuating spring weather. 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.

How do I prepare for 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 package to see if it likes full sun, partial sun, or shade, 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 flourish.

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, your perfectly spaced sprouts will pop up soon.
