Croton Temperature: Prevent Cold Shock and Leaf Drop

Croton is a warm-growing woody shrub whose leaf color and retention respond strongly to light, moisture, temperature, and abrupt change. For temperature, compare the canopy, stems, root zone, and recent environment before acting.

• leaves remain firm in stable warm conditions
• leaf drop begins after cold transport or draft exposure
• water use slows as temperature and light decline

1. Measure temperature at canopy and pot height.
2. Move away from cold glass and draft paths.
3. Acclimate gradually after transport or seasonal relocation.
4. Recheck moisture use under the new conditions.

A grower records the complete canopy, stems, deeper moisture, drainage, light direction, and temperature. They verify leaves remain firm in stable warm conditions, contrast it with leaf drop begins after cold transport or draft exposure, and make one controlled change.

• placing against cold winter glass
• moving outdoors before nights are reliably warm
• watering automatically after cold damage

Use stable leaf retention, firm stems, healthy roots, and correctly patterned new foliage as the outcome. Old scorch, spots, and lost leaves will not reverse.
