Mother and child gardening with tools

It's time to start thinking of spring. We're here to help you 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 young veggie plants and spring annuals when the frosts are through and the ground thaws. You might even want to directly sow seeds into the earth.

Plant Hardiness Zones Explained
The first thing to learn 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 plant hardiness 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. 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 a little 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 Washington, Oregon, 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 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 annuals or perennials, can also often get an indoor beginning.

Start Seeds Indoors
Grow 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 and a spray bottle of water, good soil, and patience. Then you have everything you need to try your hand at 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. That way, you'll know where your seeds should pop up. Otherwise, it'll be a surprise when the sprouts push out of the soil.

Sprouts
When your seeds have sprouted but aren't ready to go outside yet, you can still prepare them for outdoor life. 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 fan on low to mimic the wind and strengthen their stems.

Harden Your Seedlings
Harden your seedlings for strong plants. On days that are warmer than 45–50 degrees, take your pots or trays of seedlings outside to slowly warm in the shade for a couple of hours, but bring them inside at night. Cloudy days are fine, but no harsh nighttime chills or direct sunlight yet. 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, dig deeper than you think with your garden trowel and leave plenty of room around the stem. 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 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 plants that bear more fruit and flowers. 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 perfect amount.

Greet the Spring
Late winter into early spring is an exciting time in the world of gardening. Don't miss a minute of growing season. Plan your garden and landscaping, prepare to fertilize your lawn, and browse our garden center pages to find inspiration on what to plant when the weather warms. Shop for the soil, fertilizer, and seeds you need in the aisles of your E Portland Mall Garden Center, online, or on our mobile app. Let's get growing together.

Frequently Asked Questions About Gardening

What number planting zone am I in?

Check the USDA plant hardiness zone map, as planting zones have shifted slightly through 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.

When can I plant seeds in my garden?

If the soil is warm and pliable, 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 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 seeds?

The best source of info is the seed packet your garden-to-be came in. It's key to successfully growing spring flowers, fruits, and vegetables — indoors or outdoors. Requirements vary from one type of plant to the next. Certain seeds should only be sown indoors, and your seed packet will tell you that, too. For more details, check out how to plant flower 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 is the process of getting them used to the great outdoors. 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. Speak to a garden center associate or read your seed packets for more info on caring for your tender seedlings.

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 — 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 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.
