The Essential Guide to Seed Starting in Wisconsin
Starting seeds indoors is a rewarding way to get a head start on your garden, especially in Wisconsin, where the growing season is shorter. By starting your plants indoors, you ensure a stronger, more productive garden when the warmer weather arrives. Here’s what you need to know to successfully start seeds and set your garden up for success!
Equipment and Environment Needed
To give your seeds the best start, you’ll need the right equipment and growing conditions:
Seed Trays and Containers – Choose trays with drainage holes to prevent overwatering.
Seed-Starting Mix – Use a lightweight, well-draining mix designed for seed germination.
Grow Lights – Wisconsin’s winter sunlight isn’t always strong enough, so consider investing in LED or fluorescent grow lights for 12-16 hours of daily light.
Heat Mats (optional) – Many seeds, such as tomatoes and peppers, need bottom heat to germinate effectively.
Humidity Dome or Plastic Wrap (optional)– Helps retain moisture until seeds sprout.
Gentle Watering System – A spray bottle or watering can with a fine spout prevents soil disturbance.

Things to Consider
Before you start planting, think about these key factors:
Timing Matters – Check your seed packets for recommended start times. Some seeds need 6-8 weeks before the last frost, while others need less time. In Wisconsin, our rule of thumb is that after May 15th we are typically safe from frost. Decide when you want to plant your seedlings outside and work the dates backwards to when you should start your seeds.
Space Planning – Make sure you have enough room for all your seedlings as they grow.
Temperature Control – Keep the room warm (65-75°F) to encourage germination.
Hardening Off – Before transplanting outdoors, gradually expose seedlings to outdoor conditions to prevent shock.
Why You Should Start Seeds Early
There are several benefits to starting seeds indoors before spring arrives:
Stronger, Healthier Plants – Giving seeds a controlled start indoors results in more robust plants when they move outside.
Extended Growing Season – Wisconsin’s climate can be unpredictable, so starting early allows for earlier harvests and blooms.
Greater Variety Options – Many unique or heirloom varieties aren’t available as transplants in stores, but you can grow them from seed.
Cost Savings – Growing from seed is more affordable than purchasing mature plants.
What Seeds Should You Start Early?
Some plants thrive when started indoors and then transplanted after the last frost. Consider starting these seeds indoors:
Vegetables: Tomatoes, peppers, eggplants, onions, and brassicas (broccoli, cauliflower, cabbage).
Herbs: Basil, parsley, thyme, and oregano.
Flowers: Petunias, marigolds, impatiens, and snapdragons.
