🌱 Hardening Off Cilantro Starts
If you're starting with greenhouse-grown plants, proper hardening off is key to avoiding transplant shock.
🌤️ Step-by-Step Hardening Off
1. Start Slow (7–10 Days Before Planting)
Place plants outside in a shaded, protected area for a few hours
Bring back inside after exposure
2. Gradually Increase Exposure

3. Protect from Stress
Avoid strong wind and cold nights (below ~45°F)
Keep soil evenly moist

Water well after planting
Cilantro has a delicate root system, so minimizing disturbance helps plants establish quickly.
