Diagnosing Problems with Miniature Lupine

Symptom	Likely cause	Confirming sign	Action
Leaves wilting or scorching at tips in dry weather	Drought stress	Soil dry 5+ cm deep; leaf tips brown and crisp, not soft	Water Miniature Lupine 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.
