Citrus Container Size Management on indoor citrus
What's Happening
Citrus trees in containers become rootbound as they grow, eventually constricting the root ball and limiting nutrient uptake. However, moving to excessively large containers causes soil to stay wet too long, promoting root rot. The optimal container size balances adequate root space with proper drainage—typically upgrading only 2-4 inches in diameter at each repotting.
How to Fix It
- 1
Repot every 2-3 years or when roots circle pot
- 2
Increase pot size by maximum 2 inches diameter at each repot
- 3
Use containers with multiple drainage holes
- 4
Add 20-30% perlite to standard potting mix for drainage
- 5
Root prune every other year to maintain container size
How to Prevent It
Monitor root growth by sliding plant from pot annually; repot before severe root binding occurs; use unglazed terracotta to wick excess moisture
