Warm Weather Seed Starting

By Scout Nelson

Unusually warm weather and an above-average forecast are encouraging many gardeners to begin spring preparations early. One of the easiest and most rewarding ways to get ahead is to start seeds indoors. This method is affordable, simple, and helps long-season vegetables and annual flowers grow strong before outdoor planting begins.

Even if it still looks like winter outside, home can provide the perfect environment for early plant growth. With proper light, moisture, and care, seedlings can thrive indoors.

Why Start Seeds Indoors:

• Access to more seed varieties, including heirloom and unique types
• Budget-friendly option, as one packet produces many plants
• Fresh seeds often germinate better
• Ability to grow long-season crops successfully

Starting seeds indoors allows gardeners to control growing conditions and prepare healthy plants for transplanting.

Seed Starter Supply List:

• Seed packets
• Seed-starting tray with drainage
• Waterproof tray for bottom watering
• Sterile seed-starting mix
• Spray bottle
• 5000K LED or fluorescent grow lights
• Adjustable shelf or light stand
• Heat mat (optional)
• Plant labels and marker
• Small fan for gentle airflow
• Seed Starting Basics

Healthy seedlings require:

• Sterile and lightweight seed-starting mix
• Gentle watering using a spray bottle
• Steady warmth between 60 and 70 degrees Fahrenheit
• Optional heat mats for warmth-loving plants

Choose a stable indoor space instead of a windowsill. Windows can be drafty and inconsistent in temperature. A basement or spare room with stable warmth and electrical outlets for lights works best. Keep growing lights close to seedlings to prevent stretching.

After Sprouting

Once green shoots appear:

• Keep lights bright and just above the leaves
• Water lightly and regularly
• Keep soil moist but not soggy
• Harden off seedlings before moving outdoors

To harden off plants:

• Place seedlings outside in shade for a few hours
• Gradually increase sunlight and time outdoors over 7 to 10 days

Indoor seed starting is a simple way to bring spring closer and ensure strong, healthy plants for the growing season ahead.
