We combine fine peat, for efficient water management and nutrient retention, with control release fertiliser. Geraniums benefit from a pH of around 6.5, no lower than 5.5. Peat is naturally quite acidic so we add an element of magnesium lime to create the optimum pH for Geranium growth.
Best planted in areas where they will be exposed to at least 6 – 8 hours of sunlight per day, Geraniums favour moist, free draining soil. It is also best to mulch the plants to help retain water throughout the growing season.
