Frequently Asked Questions About Gardening

Which planting zone am I in?

Check the USDA zone map, as planting zones have shifted 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.

Can I plant seeds directly in the ground?

If the soil is pliable and warm, consider planting your flower, veggie, or fruit 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 seedlings and sprouts can't weather those conditions. You can also start your seeds indoors if you'd like. Consult your seed package for when and how to sow seeds.

How do I plant fruit 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 3 to 5 seeds per planting hole, then push them down with your finger. Mark where you planted them with a twig, wooden craft stick, or flag 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 in your own plant nursery, harden them before you transplant them. Hardening allows your seedlings to adjust to outdoor life, spring rains, 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 mounding a volcano of dirt around your plant, and don't tamp down the ground too tightly. Your plant baby needs to breathe.

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 require an acidic pH. 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.

Celebrate Springtime Gardening
It's time to start thinking of spring. Sweep the gazebo and clean out the shed to prepare for warmer temperatures, sprouts poking up, and fragrant breezes. Planting seeds indoors with grow lights means you'll be ready to transplant spring flowers and young veggie plants when the ground thaws and the frosts are through. You might even want to plant seeds directly into the earth. What better way to start than by exploring your favorite local plant nursery, The Garden Center in Waterloo?

Plant Hardiness Zones Explained
The first thing to learn when planting spring flowers, vegetables, 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 growing 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 — plus 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, known as direct sow. Read your seed packet for details. If you start seeds a little later than recommended, it's not ideal, but it should even out as time passes.

Gardening in Your Growing Zone
Much of the Great Plains and Upper Midwest is in Zones 3 through 5. 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, too. If you plant outside, prepare for additional warming upkeep when late frost is forecast. Planting dates are similar to Zone 4, that is to say, the target is mid-March through May 1st, depending on whether you're starting your seeds indoors or directly sowing them into your garden.

The state of Kansas and slightly north of the state line is in Zone 6, so planting can begin earlier there than farther north. The outdoor growing season doesn't kick off until mid-March or even April, although you can start some veggies by seed 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 jump on growing 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. There's less tending and planning than growing indoors. If you like to go with the flow, follow the instructions on your seed packet and try it out.

Prepare to deal with whatever hand nature deals you: You may have no germinating seeds. A critter may snack on the tender seedlings. All the seeds you plant in each hole may sprout, so you'll need to choose the most robust sprouts to survive in a process called thinning. Heavy rain might wash away the seeds. But if you're lucky, you'll get strong sprouts that are ready to grow all spring.

Start Seeds Indoors
If you'd like more control over your seedlings' journey or you're eager to get growing, start your seeds indoors in your own plant nursery. 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 sun. Keep your seeds cozy with warming 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
Carefully take your seedling out of the container. 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 ball. Place it into the hole you dug for it, even with the surrounding soil.

Protect Your Garden With Mulch
Finish your garden bed 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 controls weeds and keeps your soil from drying out. 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. Plan your garden and landscaping, prepare to fertilize your lawn, and browse The Home Depot nursery to find inspiration on what to plant when the weather warms. For those without lawns, consider adding artificial grass, a pellet grill, or an outdoor rug to your patio or balcony. Shop for the soil, fertilizer, and seeds you need in the aisles of your Waterloo Garden Center, online, or on our mobile app. Let's get growing together.
