My Seedlings Have Sprouted But Haven't Grown in Two Weeks: What to Do?
When seedlings fail to develop after germination, several factors may be at play. Here's how to troubleshoot:
Check Soil Moisture: Ensure the soil is consistently moist but not waterlogged. Overwatering can lead to root rot, while underwatering stunts growth.
Provide Adequate Sunlight: Seedlings require ample sunlight for photosynthesis. Place them in a bright, sunny location or under artificial grow lights.
Adjust Temperature: Most seedlings thrive in temperatures between 65-75°F (18-24°C). Avoid exposing them to extreme temperatures.
Fertilize Sparingly: Fertilizing too soon or with too much nitrogen can burn seedlings. Wait until the second set of true leaves appears and then apply a balanced fertilizer.
Inspect for Pests and Diseases: Insects and pathogens can damage seedlings and inhibit growth. Check for signs of pests or disease and treat accordingly.
Additional Tips:
Is it possible the seedlings are not getting enough nutrients?
- As mentioned earlier, fertilizing too soon or with too much nitrogen can burn seedlings. Wait until the second set of true leaves appears and then apply a balanced fertilizer.
Should I repot the seedlings?
- Yes, seedlings should be repotted when they outgrow their current containers. Look for roots growing out of the drainage holes or circling the inside of the pot.
How often should I water the seedlings?
- Water the seedlings when the soil feels dry to the touch. Avoid overwatering, as this can lead to root rot.
What is the best temperature for growing seedlings?
- Most seedlings thrive in temperatures between 65-75°F (18-24°C). Avoid exposing them to extreme temperatures.
What are some common pests and diseases that can affect seedlings?
- Common pests include aphids, spider mites, and whiteflies. Common diseases include damping-off, powdery mildew, and botrytis.
