Diagnosing Problems with Horse's Teeth

SymptomLikely causeConfirming signAction
Leaves wilting or scorching at tips in dry weather Drought stress Soil dry 5+ cm deep; leaf tips brown and crisp, not soft Water Horse's Teeth deeply at the base once weekly in dry spells. Mulch around the root zone to retain moisture.
Sudden wilting on one branch while rest of plant looks healthy Root rot from poor drainage in one spot Affected branch has dark, mushy roots when gently uncovered Cut back affected branch to healthy wood. Improve drainage in that area before the next growing season.
