It's time to start thinking of spring. We're here to help you prepare for sprouts poking up, warmer temperatures, and fragrant breezes. 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 directly plant seeds into the earth.

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 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. For best results, choose plants in 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, or direct sow. Be sure to read your seed packet for details. If you start seeds later than recommended, it's not ideal, but it will even out as time passes.

Gardening in Your Growing Zone
Alaska has a range of growing zones, ranging from Zones 1 and 2 in the coldest regions, to slightly warmer Zones 3 and 4, to the areas on the coast that go all the way up to Zone 8. You’re not going to grow many veggies outside for very long and will need to resort to growing tables, grow lights, and greenhouses to supplement for the cold temperatures and low-angle or lack of sunlight. For the warmer coastal regions in Zones 5–8, consider starting your plants indoors between the middle of January and March. The heart of growing season is from May 15th through the middle of September, so get your indoor starts going on time. When you hit the ground running as soon as the weather warms, you can get the most out of those five sunny months.

If you’re planting outdoors, Zone 3 options include root vegetables, greens, and cruciferous veggies. Greenhouses let you expand your range to popular vegetables that need more sun and warmer temperatures, like bell peppers, green beans, tomatoes, cucumbers, and other veggies that usually require a Zone 4 or more. If possible, plant where you can get as much sun as possible on the southern side. Root vegetables and cole crops can go on the opposite side or northwest. There are many tricks to get the best yield and results from your garden, but they vary according to where you live in this vast state. Remember to check out spring flowers, too. For full details, look into specific tips tailored to your region, whether it’s plastic mulch or sun-warmed mound gardens.

Start Seeds Indoors
Save money when you grow your garden from seeds by starting them indoors. We've got all the seed starter supplies you'll need. Veteran planters and new gardeners alike should disinfect seed trays with a watered-down bleach solution before reusing them each year. When your trays or pots are prepared, plant your seeds. As for the soil, test the mineral levels and pH to find if it needs amendments or additives. Soil pH differs among regions, and what your plants need depends on what you're growing. Most veggie plants prefer a pH of 5.5–7.5. Soil amendments can tip the balance of your soil in a direction that'll help your plants.

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 plant tag or toothpick. That way, you'll know where your seeds should pop up, and you'll know they're not weeds. Otherwise, it'll be a surprise when the sprouts push out of the soil.

Sprouts
Prepare your seed sprouts for outdoor life while they're still indoors. These inch-tall micro-seedlings are fragile but 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 floor fan on low to mimic the wind and strengthen their stems.

Harden Your Seedlings
Harden your seedlings for strong plants. On days above 45 degrees, take your trays or pots of seedlings outside to slowly warm in the shade for two hours, but bring them inside at night. A cloudy day will also work well. Gradually add an extra hour or two each day, gently introducing your plants to the sun. After a week or more of this, you can leave them out overnight if the temps stay at 50 degrees or above at night. Cover your plants if they're in the ground and a late-season frost sneaks back in.

Transplant Young Plants Into Their New Homes
When your plants have three or four true leaves — different from mini seedling leaves – it's time to 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 any fertilizer as directed on the package, either in the hole or on top of the soil after it's planted. 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 flower bed with mulch and compost. Compost enriches the soil so your garden can grow even better. It may help foster stronger plants that bear more flowers and fruit. Mulch controls weeds and keeps the soil moist. Mulch and compost 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.
