Grapefruit – Marsh

Citrus × paradisi ‘Marsh’
White Grapefruit | Classic pale-fleshed grapefruit with mild, refreshing flavour

The ‘Marsh’ Grapefruit is a time-honoured citrus cultivar known for its smooth, pale-yellow rind and translucent, nearly seedless white flesh. It offers a gentle sweetness balanced by a light tang — less acidic than most red varieties — making it perfect for fresh eating or juicing. A dependable and heavy-bearing tree, ‘Marsh’ performs beautifully in full-sun gardens and also adapts well to large containers.

Plant Care

Sun: Full sun — essential for vigorous growth, sweet flavour, and consistent fruiting.
Soil: Fertile, well-drained, and slightly acidic to neutral. Enrich sandy soils with compost and organic matter.
Water: Moderate — keep soil evenly moist, especially during flowering and fruit development; avoid waterlogging.
Fertiliser: Apply a balanced citrus fertiliser in early spring and again in midsummer. Supplement with trace elements (iron, magnesium, manganese) if foliage becomes pale.
Pruning: Light pruning after harvest to shape the canopy and improve airflow; remove dead, damaged, or crossing branches.
Top tip: Mulch generously around the base to retain soil moisture and suppress weeds. Protect from frost and cold winds, especially when young or in containers.
