📝 Growing Notes
Grapefruit trees are among the largest and most vigorous citrus, requiring more space than lemons or limes. Comfrey provides an excellent mulch source and deep nutrient cycling beneath the wide canopy. Like all citrus, grapefruits benefit from marigold companions that suppress nematodes in the root zone.
