Enter your preferred material, the square footage and mulch depth of the coverage space for accurate results.
We'll calculate the amount of fencing you should purchase based on your property needs.
What number planting zone am I in?
Check the USDA growing 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 ground isn't frozen solid and the soil isn't cold, 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 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 veggie seeds?
Read your seed envelope for the best info on how to grow fruits, veggies, and spring flowers — indoors or outdoors. Requirements vary with each seed type. Some seeds should only be sown indoors, and your seed envelope will tell you that, too. You'll be a pro at planting seeds in no time.
Should I harden off my seedlings before planting them outside?
Yes, for best results, if you raised plants indoors from seeds in your own plant nursery, harden them before you transplant them. Hardening is the process of getting them used to outdoor life, spring rains, 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.
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 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. 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. 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 cucumbers and eggplant, 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
On beautiful spring days, tidy the yard before everything blooms in earnest. Planning your garden lets you make the most of your time and space. Don't forget to sweep the gazebo and clean out the shed in preparation for spring, too. No matter which plants you need and what outdoor projects you choose to tackle, you'll find that The Home Depot Garden Center in Covington, WA is the local plant nursery to 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 by climate. Find your zone on the USDA planting 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. You'll have good results with plants that have your zone number or less. 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. Be sure to 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 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, 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 perennials or annuals, can also often get an indoor beginning.
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 reliability and spacing compared to indoor starts. However, if you like to go with the flow, follow the instructions on your seed packet and try it.
Prepare to deal with whatever hand nature deals you: Be ready for none of your seeds to sprout, all of them to come up, and anything in between. Your seedlings will need to survive wind, rain, and sudden cold temperatures, as well as critters and bugs that crave tender greens. 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 rain and sunlight. Keep your seeds warm 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
Place your transplants in the ground, then water them well. Surround them with mulch, marking where the plant is with a stick or tag so you can easily find it among the grass clippings, old leaves, or straw. Consider putting up chicken wire or other protective measures if deer or rodents visit your yard regularly, as your sprouts may otherwise become a snack.
Protect Your Garden With Mulch
Finish your flower bed with mulch and compost. Mulch controls weeds and keeps the soil moist. Compost enriches the soil so your garden can grow even better. It may help foster larger and stronger 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
Don't miss a minute of growing season. Prepare to fertilize your lawn, plan your garden and landscaping, 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 seeds, fertilizer, and soil you need in the aisles of your Covington, WA Garden Center, online, or on our mobile app. Let's get growing together.
