How to Start Seeds Indoors for a Head Start on Gardening

Getting a jump start on the growing season is easy when you know how to start seeds indoors. With the right timing and supplies, you can cultivate robust seedlings ready for transplanting. Here is a step-by-step guide to starting your garden early.

When to Start

Consult your USDA Hardiness Zone and seed packets to determine ideal starting times. In general, start 6-8 weeks before your last expected frost date. Leafy greens and herbs can be started up to 10-12 weeks before transplanting outside. 

Supplies Needed

- Seed starting mix - Use a sterile, soilless mix to avoid disease

- Containers - Cell packs, trays, peat pots work. Make sure they have drainage holes

- Grow lights - Flourescent bulbs provide the right light intensity for seedlings

- Heat mat (optional) - Warms soil for better germination rates

- Plastic dome or wrap - Helps retain moisture while seeds germinate

Step-By-Step Process

1. Fill containers with moistened seed starting mix, firming gently. 

2. Sow seeds according to packet directions; cover lightly with mix.

3. Use plastic domes or wrap to retain moisture during germination.

4. Provide 14-16 hours of daily light once sprouted until transplanting. 

5. Keep soil moist but not soggy. Water from below to avoid damping off.

6. Remove any weak or diseased seedlings to avoid spreading issues.

7. Harden off plants before transplanting by gradually exposing them to outdoors.

8. Transplant on a calm, cloudy day, being careful of roots.

Be Patient! Seeds take time to emerge and grow. Provide consistent light, warmth, and moisture until it's time to transplant your sturdy seedlings outside.
