Frequently Asked Questions About Gardening

Which planting zone am I in?

Check the USDA plant hardiness 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.

What does direct sow mean?

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

How do I plant seeds?

Follow the advice on your seed package. It'll tell you when to start them indoors and when to direct sow. 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 toothpick so you don't accidentally confuse them with 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 first 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 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'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, you'll have perfectly spaced sprouts pop up soon.

Set Up For Springtime
It's time to start thinking of spring. Clean out the shed and sweep the gazebo to 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 spring annuals and young veggie plants when the frosts are through and the ground thaws. You might even want to sow seeds directly into the earth. What better way to start than by exploring your favorite local plant nursery?

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 into blocks 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. You'll have good results with plants that have your zone number or less. In other words, a Zone 7 garden can support plants listed as Zones 1–7. The timeframe to direct sow outdoors in your garden is often around a month later than the indoor start date. Read your seed packet for details. If you start seeds later than recommended, it's not ideal, but it will likely even out as time passes.

Gardening in Your Growing Zone
In the Pacific Northwest, Montana, and Idaho, there’s a wide range of climates and growing zones. Most of Oregon, Washington, and Idaho are Zones 6–9, with the higher peaks coming in as Zones 4–5. Montana is in Zone 5 on the western end, but the mountainous regions are mostly Zone 4, with the tallest mountains as Zone 3.

The differences in planting zones means your seed sowing times will vary. The coastal regions in Zones 8 and 9 can start many seeds indoors in mid-January. Colder regions in 6–8 should wait a little longer to plant, and all these zones need to wait an additional month before planting seeds outdoors rather than indoors. Mountainous regions in Zones 3 to 5 will have the shortest growing season, with seed starters going in later in the spring. Although the weather may vary, waiting until the frost has passed will give your seeds the best chance at a hearty and healthy life.

Popular veggies of all kinds, including cucumbers and tomatoes, are fine with an early spring or late winter start indoors under the grow lights. Your spring flower seed choices, whether they're perennials or annuals, can also often get an indoor beginning.

Plant Seeds Outside With Direct Sow
Planting seeds into your garden soil, or using the direct sow method, is an alternative option. There's less tending and planning than growing indoors. If you like to go with the flow, follow the instructions on your seed package and give it a try.

Your seeds might get washed away or struggle to grow, or critters or insects 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 hardy and primed to survive, 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 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 sunlight and rain. Keep your seeds cozy 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
When your plants have three or four real leaves — different from mini seedling leaves — 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 room with nutrient-rich topsoil. Apply fertilizer as directed. Only apply as much as recommended, as you could burn and kill the plant instead of helping it along.

Protect Your Garden With Mulch
Finish off your garden with compost and mulch. Mulch keeps your soil moist and controls weeds. Compost enriches the soil so your garden can grow even better. It may help foster larger plants that bear more flowers and fruit. 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 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 which spring flowers to plant when the weather warms. For those without lawns, consider adding an outdoor rug, artificial grass, or a pellet grill to your patio or balcony. Shop for the soil, fertilizer, and seeds you need in the aisles of your Southcenter Garden Center, online, or on our mobile app. Let's get growing together.
