The most refreshing citrus you can grow, and one that performs reliably in Perth's warm climate. Grapefruit trees are large, handsome, and productive - the fruit is best eaten fresh in segments or juiced, and that first cold glass of freshly squeezed grapefruit on a Perth morning is reason enough to plant one. Full sun, well-drained soil. Deep watering through summer is important for fruit quality and size. Feed with citrus fertiliser in spring and autumn. Trees can get large - allow room or manage with annual pruning after harvest.
