Sudden Leaf Drop on Dracaena marginata: Troubleshooting Light, Temperature, and Water

Three Main Causes

1. Light: Must be directly in front of an uncovered window. A few feet away = too dark.
2. Temperature: Below 60°F or cold drafts cause instant leaf drop.
3. Watering: "Sparingly" is vague. Water thoroughly when top ½ inch of soil is dry. Both over- and under-watering cause leaf drop.

Conservatory Caution

Conservatories can overheat by day and freeze at night. Monitor min/max temps.

Action

• Move to the brightest indoor window.
• Keep above 60°F always.
• Water on the "top half-inch dry" schedule.

New leaves will emerge if the roots are alive and conditions improve.
