Mother and child gardening with tools

It's time to start thinking of spring. We're here to help you prepare for warmer temperatures, fragrant breezes, 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 flowers when the ground thaws and the frosts are through. You might even want to directly sow organic seeds into the earth.

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 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, and all the zones numbered less than that. In other words, a Zone 9 garden can support plants listed as Zones 1–9. You can plant seeds indoors roughly a month before you can plant them outside, or direct sow. Read your seed packet for details. If you start them 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, New Hampshire, Vermont, 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. Target planting dates are roughly mid-March through May 1st, depending on whether you're direct sowing or starting your seeds indoors.

Much of West Virginia, Ohio, Pennsylvania, Massachusetts, New Jersey, southern New York state, and Connecticut 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, cucumbers, peppers, squash, onions, and other classic garden crops will thrive in this region, and most of them can get an early start indoors before spring really moves in.

Plant Seeds Outside With Direct Sow
Planting seeds with the direct sow method, right into the soil, is another option. It doesn't give you as much organized planning in terms of reliability and spacing compared to indoor starts. However, if you like to go with the flow, follow the instructions on your seed pouch and try it out.

Your seeds might get washed away or struggle to grow, or bugs or critters might eat the sprouts. But if you're really fortunate, you might get a strong sprout from each place you sowed seeds, perfectly spaced and ready to grow all spring. The reality of your garden will usually be somewhere in between, and spreading out tiny sprouts throughout the soil isn't so bad. You know those sprouts are primed to survive and hardy, although there are no guarantees in the long term.

Start Seeds Indoors
If you'd like more control over your seedlings' journey or you're eager to get growing, start your seeds indoors instead. 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 warm 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
Carefully take your seedling out of the container. A good way to do this is to turn it upside-down or sideways and gently squeeze the plastic to break the seal. If your transplant grew in the garden, dig deeper than you think with your garden trowel and leave plenty of room around the stem. You don't want to damage the roots. Place it into the hole you dug for it, even with the surrounding soil.

Protect Your Garden With Mulch
Finish off your garden with compost and mulch. Compost enriches the soil so your garden can grow even better. It may help foster stronger and larger plants that bear more flowers and fruit. Mulch keeps your soil from drying out and controls weeds. Compost and mulch can be DIY creations, but you can also purchase them in-store. The next time you're looking for "mulch near me," stop by the Garden Center to get the perfect 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. Plan your garden and landscaping, prepare to fertilize your lawn, and browse our garden center pages to find inspiration on which spring flowers to plant when the weather warms. Shop for the soil, seeds, and fertilizer you need in the aisles of your Milltown Garden Center, online, or on our mobile app. Let's get growing together.

Frequently Asked Questions About Gardening

What's my planting zone?

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. Increase your odds of successful gardening by choosing plants that are meant for your zone.

When can I plant seeds outside?

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

How do I plant seeds?

Follow the directions on your seed package. It'll tell you when to start them indoors and when to plant them outside. Generally, you'll add three to five seeds per planting hole, then push them down with your finger. Mark where you buried the seeds with a flag, wooden craft stick, or twig so you don't mistake them for weeds later.

Should I harden off my seedlings before planting them outside?

Yes, for best results, if you raised plants indoors from seeds, harden them before you transplant them. Hardening allows your seedlings to adjust to the great outdoors and rain, sun, 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.

How do I plant a transplant or baby plant?

Squeeze the plastic around the plant to loosen the soil. Carefully coax the plug of dirt with the plant into your palm, then place it into the hole you dug for it. Make sure the top of your transplant's soil is even with the garden soil, and carefully press the earth into place. Avoid leaving the plant as an island with a moat around it, and don't pack the ground too tightly. Your plant baby needs to breathe.

What are seed tapes?

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