Mother and child gardening with tools

On those beautiful days, clean up the yard before everything blooms in earnest. Lawn care is often a priority, 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 Garden Center in Middletown, DE can help you enjoy your spring activities to the fullest.

Plant Hardiness Zones Explained
The first thing to know when planting vegetables, 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 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. 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 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 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 directly sowing them into your garden 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 do well in this region, and most of them can get an early start indoors before spring really moves in.

Start Seeds Indoors
You can 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. Make sure you have a warm and sunny spot that gets at least 12 hours of light. Then you have everything you need to try growing seeds. Early spring light isn't usually strong enough, so we recommend extra lighting to keep those seeds warm enough to germinate.

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 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
Harden your seedlings for best results later. On days above 45 degrees, take your trays or pots of seedlings outside to slowly warm in the shade for a couple of hours, but bring them inside at night. They're not ready for direct sunlight yet or harsh nighttime temps. Gradually add more outside time each day, incorporating a little sun to get your plants used to it. After a week or more of this, you can leave them out overnight if the temps stay above 50 degrees. Cover your plants if they're in the ground and a late-season frost sneaks back in.

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, 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 system. 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. 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 perfect amount.

Greet the Spring
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 seeds, fertilizer, and soil you need in the aisles of your Middletown, DE 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 planting zone map, as planting zones have changed slightly over the years. 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. 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 package for how and when to sow seeds.

How do I plant fruit seeds?

The best source of info is the seed envelope your garden-to-be came in. It's key to successfully growing spring flowers, fruits, and vegetables — indoors or outdoors. Requirements vary with each seed type. Certain seeds should only be planted indoors, and your seed packet will tell you that, too. For more details, check out how to grow a garden from seeds.

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.

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 floor 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.

Should I use peat moss starters or coir starters?

Seed starters, full of nutrients in convenient pellets or 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 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.
