Frequently Asked Questions About Gardening
What planting zone am I in?
Check the USDA plant hardiness 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.
Can I just put seeds in the ground?
If the soil is pliable and warm, consider planting your fruit, flower, 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 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 3 to 5 seeds per planting hole, then press them into the soil as directed. Mark where you buried the seeds with a flag, toothpick, or twig so you don't think they're 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 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.
Can I strengthen my seedlings before planting them outdoors?
Get your sprouts used to storms and breezy spring days 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. They'll gain strength even though you shouldn't see them moving. 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 alike. 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. Clean the shed and sweep out the gazebo to prepare for warmer temperatures, fragrant breezes, and sprouts poking up out of the ground. Planting seeds indoors means you'll be ready to transplant young veggie plants and spring flowers when the ground thaws and the frosts are through. You might even want to sow organic seeds directly into the earth. What better way to start than by exploring your favorite local plant nursery, The Home Depot E Kennewick Garden Center?
Plant Hardiness Zones Explained
The first thing to learn when planting veggies, 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. For best results, choose plants in your zone number or less. In other words, a Zone 6 garden can support plants listed as Zones 1–6. You can plant seeds indoors roughly a month before you can plant them outside, known as direct sow. Be sure to read your seed packet for details. If you start plants a little later than recommended, it's not ideal, but it will even out as time passes.
Gardening in Your Growing Zone
In the Pacific Northwest, Idaho, and Montana, there’s a wide range of climates and growing zones. Most of Idaho, Oregon, and Washington 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, wait until the frost has passed to give your seeds the best chance at a 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 annuals or perennials, 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 pouch and try it.
Prepare to deal with whatever hand nature deals you: You may have no seeds that germinate. A critter may snack on the tender seedlings. All the seeds you plant in each hole may sprout, so you'll need to thin them out by only leaving the most robust sprouts. Garden pests or insects might make a meal out of your seedlings before they take off. But if you're lucky, you'll get strong sprouts that are ready to grow all spring.
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 in your own seedling garden. 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 warm with warming 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 true 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 great, dig a slightly bigger hole and fill the extra space with nutrient-rich topsoil. Apply fertilizer as directed. Only apply as much as recommended, as you could burn the plant and kill it instead of helping it.
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. 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
Don't miss a minute of growing season. 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 balcony or patio. Shop for the seeds, fertilizer, and soil you need in the aisles of your E Kennewick Garden Center, online, or on our mobile app. Let's get growing together.
