Tropical Growing Tips for Chives
Recommended Varieties
- Common chives
- Garlic chives (Allium tuberosum) - even more heat tolerant
Key Challenges
- Heat stress above 35C
- Rust in humid conditions
- May need rest period in wet season
Pro Tips
- Garlic chives outperform common chives in tropics
- Morning sun, afternoon shade

Harvesting Chives
When ready: Harvest when leaves are 15cm+ tall. Use scissors to cut to 2-3cm above soil level.
How to harvest: Cut entire clump to 2-3cm with sharp scissors. Leaves regrow in 2-3 weeks. Do not pick individual leaves - cutting the whole clump promotes even regrowth.
