Starting seeds indoors is a smart way to get a jump on the growing season, especially if you live in a climate with a short summer. With just a few tools and a little knowledge, you can grow strong, healthy seedlings ready to transplant into your garden when the weather warms.
Why Start Seeds Indoors?
- Extended growing season: Get a head start on crops like tomatoes and peppers.
- More variety: Access heirloom and specialty seeds not found at garden centers.
- Cost savings: One packet of seeds can yield dozens of plants.
- Stronger plants: Control conditions early for healthier starts.
What You Need to Get Started
- Seed trays or containers (with drainage)
- Seed-starting mix (light, sterile, and well-draining)
- Labels (trust us—don’t skip this!)
- Clear cover or humidity dome
- Grow lights (or a sunny window with 6–8 hours of light)
- Seeds (read packets carefully for timing and depth)
Steps to Start Seeds Indoors
- Fill containers with seed-starting mix
- Moisten the soil before planting
- Sow seeds at the correct depth
- Cover and keep warm (65–75°F is ideal)
- Remove the cover once seeds sprout
- Provide strong light for 12–16 hours/day
- Water from below to avoid disturbing seedlings
- Thin seedlings to avoid overcrowding
Transplanting Seedlings
Before transplanting outdoors:
- Harden off: Gradually expose seedlings to outdoor conditions over 7–10 days
- Water well before and after planting
- Plant on a cloudy day or in the evening to reduce transplant shock
Common Mistakes to Avoid
- Overwatering or underwatering
- Starting too early (check your zone!)
- Poor lighting = leggy, weak seedlings
- Skipping the hardening-off process
Final Thoughts
Starting seeds indoors can seem intimidating, but it's incredibly rewarding. With a little preparation and patience, you'll be on your way to growing strong, healthy plants before your neighbors even break out their trowels.
