What number planting zone am I in?
Check the USDA plant hardiness zone map, as planting zones have shifted slightly over time. Zones with bigger numbers can begin planting earlier in the year. Increase your odds of successful gardening by planting veggies, flowers, and trees that are meant for your zone.
Can I "direct sow" seeds outside?
If the soil is starting to warm, consider planting your fruit, veggie, or flower seeds directly into your garden bed. This is called "direct sow." Plant after the possibility of frost has passed for the season, as seedlings and sprouts can't survive those conditions. You can also start your seeds indoors if you'd like. Read your seed packet to learn when and how to plant your seeds.
How do I plant flower seeds?
Follow the instructions on your seed packet to learn how to plant a flower garden from seed. It'll tell you when to start them indoors and when to direct sow. Generally, you'll press 3–5 seeds into the soil as directed. Use a craft stick, twig, or flag to mark the seeds, so you don't think they're weeds and pull them up.
Do you have organic vegetable plants and seeds?
We've got a variety of organic options, including organic veggie seeds and fruit seeds, as well as organic herb and flower seeds that are subject to availability. We carry the organic soil to plant them in as well as the organic fertilizer to feed your plants.
How can I strengthen my seedlings before planting them outdoors?
Get your sprouts used to breezy days and storms with a fan. It'll also help keep fungi 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. This makes them more resilient against wind gusts. If you don't set up a fan, your seedlings may be more sensitive to strong winds. Try to plant between storms.
Should I put my transplants in full sun?
Before you put your seedlings in the ground, ensure that they will have the right amount of sun, it's warm enough outside, and the soil is healthy. Check your seed envelope to see if they like full sun, shade, or partial sun, as well as what time of year they should be planted. Space your plants as described on the seed package for best results. That way, your plant babies have enough space to flourish.
Should I use peat moss or coir seed 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 eggplant and cucumbers, 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 out the shed and sweep the gazebo to prepare for fragrant breezes, warmer temperatures, and sprouts poking up out of the ground. Planting seeds indoors with grow lights means you're ready to transplant young veggie plants and spring annuals when the ground thaws and the frosts are through. You might even want to plant 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 learn when planting spring flowers, veggies, and other seeds is your planting zone. Every location in the United States and its territories is sorted into blocks by climate. Find your zone on the USDA growing zone map and learn when to plant flower bulbs and 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 6 garden can support plants listed as Zones 1–6. The timeframe to direct sow outdoors in your garden is often around a month later than the indoor start date. Always read your seed envelope for details. If you start your seeds later, it's not ideal, but it will likely even out as time passes.
Gardening in the Great Plains and Upper Midwest
Much of the Upper Midwest and Great Plains is in Zones 3, 4, and 5. Your best bets for veggies will be root vegetables like beets and carrots, leafy greens including lettuce, and cruciferous veggies like cabbage and kale. You can try squash, too. If you plant outside, prepare to cover outdoor seedlings when frost is in the forecast. Planting dates are similar to Zone 4, that is to say, the target is mid-March through May 1st, depending on whether you're directly sowing them into our garden or starting your seeds indoors.
The state of Kansas and slightly north of the state line is in Zone 6, so planting can begin earlier there than farther north. The outdoor growing season doesn't begin until mid-March or even April, although you can start some veggies by seed halfway through February. Peppers, cucumbers, tomatoes, onions, and other classic garden crops will thrive in this region, and most of them can get an early jump on growing indoors before spring arrives.
Plant Seeds In Your Garden With Direct Sow
Direct sow, or planting seeds directly into outdoor garden soil, is another way of gardening. If you prefer to go with the flow, follow the instructions on your seed packet. Direct sow timeframes are later than indoor planting because the soil must be warm enough.
There's more variation with seed survival with direct sow. Your seedlings need to survive hungry rodents and storms, weather too much rain or sun, and obtain proper nutrition. Prepare to deal with whatever nature gives you. If you're lucky, you'll get strong sprouts that are ready to grow all spring.
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 a month before you can do it outside. Like direct sow, you push the seeds into the soil as directed on the seed package, but that's where the similarities end. Seed trays make it easier to transplant later.
You're responsible for giving them quality substitutes for rain and sunlight. Keep your seeds warm with grow lights and heating mats, 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
In quality soil, dig a hole that's bigger than or the same size as your plant's dirt plug. Place your transplant in the ground, and fill any extra space with nutrient-rich topsoil. Apply fertilizer if desired inside the plant hole or on top of the dirt, then water them well without overdoing it. Never apply more fertilizer than recommended, as too much could harm the plant. Consider putting up chicken wire or other protective measures if deer, squirrels, or chipmunks visit your yard regularly, as your sprouts may otherwise become a snack.
Enrich Your Garden With Mulch
Nourish your garden bed with compost and mulch. Compost enriches the soil so your garden can grow even better. Mulch keeps your soil from drying out and controls weeds. It may help foster larger plants that bear more flowers and fruit. Mulch and compost can be DIY creations, but you can also purchase them in-store. The next time you're searching for "mulch near me," stop by the Garden Center to get the correct amount.
Greet the Spring
Don't miss a minute of growing season. Prepare to fertilize your lawn, plan your garden and landscaping, and browse your nearest plant nursery to find inspiration on which spring flowers to plant when the weather warms. If you don't have a lawn, consider adding artificial grass, an outdoor rug, or a pellet grill to your balcony. Shop for the soil, seeds, and fertilizer you need in the aisles of your Mukwonago Garden Center, online, or on our mobile app. Let's get growing together.
