Chlorosis of gardenia

Disease Information

Chlorosis

Symptoms and damage

Pale green leaves with dark green veins; yellowing of foliage.

A lack of normal green pigmentation in foliage, generally due to deficiency of one or more micronutrients (usually iron), root rot, or root-knot nematodes; some leaf yellowing on older leaves is normal

Control

Acidify the soil with aluminum sulfate, iron sulfate, or wettable sulfur. Iron chelate may be used on the soil or foliage. An acidulating houseplant fertilizer can be used to lower soil pH. Allow the soil to remain evenly moist but not saturated.
