Sweet Potato Vine (Ipomoea batatas) Crystal Deposits: Exudate, Not Disease

Diagnosis: Exudate (Plant “Sweat”)

Crystal-like deposits on leaves/stems when dry = dried guttation fluid (exudate). Not fungus, pest, or disease.

Solution

Simply avoid letting the plant get dry. Keep evenly moist. The crystals disappear and don’t recur.

No Treatment Needed

No fungicide. No pest control. Just consistent moisture.
