Highbush Blueberry + Clover

White clover works well as a living mulch in blueberry rows, suppressing annual weeds and fixing modest amounts of atmospheric nitrogen without sending deep roots into the same zone blueberries depend on. The pairing suits established plantings better than new ones: in the first two to three years after transplanting, even low-growing groundcovers can slow establishment by competing for water during dry spells.

One compatibility tension worth noting: highbush blueberry performs best at soil pH 4.5 to 5.5, while white clover prefers pH 6.0 and above. In a properly acidified blueberry bed, clover may thin out or yellow rather than thrive. The pairing works most reliably in the drive rows between blueberry hedgerows, where pH management is less strict, rather than directly beneath the canopy. Mow clover before it sets seed if unwanted spread into the planting bed is a concern.
