Diagnosing Brown Spots on Lantana in a Container

Possible Causes (The “Too’s”)

• Too much / too little water
• Too much / too little sun
• Too much heat
• Too much / too little fertilizer
• Water on leaves + sun = leaf scorch

Immediate Actions

1. Remove all brown leaves.
2. Check soil: water thoroughly until it drains out, then let dry before next watering.
3. Place in bright but not scorching light (morning/late afternoon sun).
4. Inspect roots: if root‑bound, repot in fresh potting mix.

Cold Hardiness

Lantanas freeze below 40 °F. If your balcony gets that cold, bring it inside for winter.

By eliminating the stressed foliage and correcting the cultural “too’s,” the plant should push healthy new growth.
