Do not assume

Do not copy a care rule from another plant. Use this profile to adjust the general symptom framework before watering, repotting, fertilizing, or treating.

Plant-specific checks

Feel the cane base for softness before adding water.

Check whether lower yellow leaves are old leaves or a spreading pattern.

Keep it away from cold doorways and air conditioning.
