Troubleshooting
Cook Pine problems — and how to fix them
Cook Pine (Araucaria columnaris) is generally forgiving once you match its basics, but a few issues come up again and again. Here is what each one looks like, why it happens, and the fix.
Browning foliage tips
Dry air or erratic watering browns the scale-like foliage. Keep moisture even and humidity moderate, and keep the plant away from heat sources and cold drafts.
Sparse, leaning growth
Too little light exaggerates stretching and an uneven habit. Provide the brightest light possible and rotate the pot to balance growth.
Root rot
Overwatering and poor drainage rot the roots and yellow the foliage. Plant in free-draining soil and let the surface dry between waterings.
Outgrowing indoor space
Vigorous upward growth eventually makes it too tall for a room. Pot up gradually and plan to move large specimens outdoors in frost-free climates.
Prevent cook pine problems before they start
Most cook pine issues are care-mismatch, not bad luck. Dial in the basics:
