How To Avoid Leggy Seedlings
Leggy seedlings happen when young plants grow tall, thin, and weak because they don’t get enough light or the right conditions. Here’s how to avoid that:
How to Avoid Leggy Seedlings
1. Provide Plenty of Light
- Use a bright south-facing window or grow lights for at least 12–16 hours a day.
- Keep seedlings close (2–3 inches) to the light source but not so close that they get burned.
2. Maintain Proper Temperature
- Keep temperatures between 65–75°F (18–24°C).
- Avoid overly warm rooms which encourage rapid, weak growth.
3. Avoid Overcrowding
- Thin seedlings early to prevent competition for light and nutrients.
4. Use Good Quality Seed Starting Mix
- A well-draining, nutrient-rich mix supports healthy root and stem development.
5. Water Properly
- Keep soil moist but not soggy.
- Overwatering can weaken seedlings.
6. Provide Air Circulation
- Use a gentle fan to strengthen stems by simulating a breeze.
- Good airflow reduces disease risk.
7. Harden Off Seedlings Before Transplanting
- Gradually expose seedlings to outdoor conditions to toughen them up.
