Mother and child gardening with tools

It's time to start thinking of spring. We're here to help you prepare for sprouts poking up, fragrant breezes, and warmer temperatures. 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 directly sow organic seeds into the earth.

Plant Hardiness Zones Explained
The first thing you should 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 plant hardiness 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. Be sure to read your seed packet for details. If you start them a little later than recommended, it's not ideal, but it will likely 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 direct sowing or starting your seeds indoors.

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

Start Seeds Indoors
Grow 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 grow lights or a warming mat to go with your seed tray or planter pots. If you're planting a larger garden, use seed trays — like the ones you see sprouts in at your Newton Garden Center — to make it easy to stay organized and plant tiny soil plugs later. 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 toothpick or plant tag. That way, you'll know where your seeds should pop up, and you'll know they're not weeds. 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 micro-seedlings are fragile — only an inch or so high, with the tiniest seedling leaf or two — but they're resilient. Seedlings certainly 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 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 just enough, but not too much. Whisk wilted plants inside and give them a good drink, making sure they're healthy before setting them outdoors again.

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 make sure it's even with the surrounding soil.

Protect Your Garden With Mulch
Finish it 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 flowers and fruit. Mulch and compost 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 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 which spring flowers to plant when the weather warms. Shop for the soil, fertilizer, and seeds you need in the aisles of your Newton Garden Center, online, or on our mobile app. Let's get growing together.

Frequently Asked Questions About Gardening

How do I check my USDA 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.

What's direct sow in gardening?

If the soil is warm and pliable, consider planting your fruit, veggie, or flower seeds directly into your garden. This is called the "direct sow" method. Plant 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 how and when to sow seeds.

How do I plant seeds?

Read your seed packet for the best info on how to grow fruits, veggies, and spring flowers — indoors or outdoors. Requirements vary with each seed type. Some seeds should only be sown indoors, and your seed envelope will tell you that, too. For more details, check out how to plant flower seeds.

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 is the process of getting them used to the great outdoors and sun, rain, and temperature swings. 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 strengthen my seedlings before planting them outdoors?

Get your sprouts used to breezy spring days and storms with a fan and keep fungus from growing in damp conditions. Set up an oscillating fan on low to mimic the wind. Just the gentlest breeze for several hours a day will do the trick — no need to prep them for a hurricane. The stems and leaves will get used to blowing in the breeze and not snap when a gust comes through. If you don't set up a fan, your seedlings may be more sensitive to strong winds. Try to plant between storms.

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.
