Jasmine Tree Leaf Drop: Cold Snap, Water, or Insects?

An 8-month-old jasmine (likely lakeview or orange jasmine) in Port St. Lucie dropping 85% of leaves after a 40°F night may be reacting to cold shock, underwatering, or insects.

Checklist

Cold: Jasmines in Sarasota survived similar temps. Possible but not certain.
Water: Winter watering still needed. Fertilizer without water dehydrates roots.
Insects: Check leaf undersides for black dots (chewing/sucking pests). Use magnifier.

Action

Resume regular watering.
If bugs found: spray 100% neem oil—it’s fungicide, miticide, and insecticide, and doesn’t wash off.
Fertilize lightly only if watering is consistent.
