It's time to start thinking of spring. We're here to help you prepare for sprouts poking up, warmer temperatures, and fragrant breezes. Planting seeds indoors means you'll be ready to transplant spring flowers and young veggie plants when the frosts are through and the ground thaws. You might even want to directly plant organic seeds into the earth.

Plant Hardiness Zones Explained
The first thing to know when planting spring flowers, veggies, 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 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 5 garden can support plants listed as Zones 1–5. 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 plants 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 broccoli 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 direct sowing.

Much of Ohio, Pennsylvania, West Virginia, 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.

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 space and reliability as starting indoors. However, if you like to go with the flow, follow the instructions on your seed pouch and try it.

Your seeds might struggle to grow or get washed away, or insects or animals might eat the sprouts. But if you're really lucky, you might get a strong sprout from each place you sowed seeds, perfectly spaced and ready to grow all spring. The reality of your sown seeds 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.

Start Seeds Indoors
If you're eager to get growing or would like more control in the care and feeding of seedlings, 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 cozy with heat mats and grow lights, water them carefully with a mister 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
When your plants have three or four real leaves — different from mini seedling leaves – it's time to transplant them. In quality soil, dig a hole the same size as the dirt plug where your transplant has been growing. If your ground soil isn't fantastic, dig a slightly bigger hole and fill the extra space with nutrient-rich topsoil. Apply any fertilizer as directed on the package. Only apply as much as recommended, as you could burn the plant and kill it instead of helping it along.

Protect Your Garden With Mulch
Finish your garden bed 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 and larger plants that bear more fruit and flowers. 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. Plan your garden and landscaping, prepare to fertilize your lawn, and browse our garden center pages to find inspiration on what to plant when the weather warms. Shop for the soil, fertilizer, and seeds you need in the aisles of your Downingtown Garden Center, online, or on our mobile app. Let's get growing together.

Frequently Asked Questions About Gardening

What number planting zone am I in?

Check the USDA growing zone map, as planting zones have changed slightly over 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 ground isn't frozen solid and the soil isn't cold, consider planting your veggie, fruit, 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 seedlings and sprouts can't weather those conditions. You can also start your seeds indoors if you'd like. Consult your seed envelope for when and how to sow seeds.

How do I plant vegetable seeds?

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

Do I have to harden off my seedlings before planting them outside?

Yes, if you raised plants indoors from seeds, harden them first before you transplant them. Hardening allows your seedlings to adjust to the great outdoors, 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.

What should I do before planting seeds or transplants outside?

Before you plant, make sure that the soil is healthy, it's warm enough outside, and your plant will have the right amount of sun. Check your seed envelope to see if it likes shade, full sun, 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.

Should I use peat moss starters or coir starters?

Seed starters, full of nutrients in pots or pellets, 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 need acidic soil. 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.
