YEL­LOW PERIL – GARDENIA ALERT

Hauraki Herald - - GARDENING -

Yel­low leaves sig­nal that acidlov­ing plants like gar­de­nias, daphnes and camel­lias need at­ten­tion. The soil may con­tain the nu­tri­ents plants need for healthy growth but the nu­tri­ents aren’t ac­ces­si­ble if the pH bal­ance isn’t right for the plant. Give yel­low-leafed gar­de­nias a fo­liar spray and wa­ter the root zone with Ep­som salts (mag­ne­sium sul­phate) – 1 tea­spoon to 4 litres wa­ter – and they’ll green up very quickly. Or use Se­que­strone which has ad­di­tional trace el­e­ments.
