Pear and Clover

Clover planted beneath pear trees serves two practical functions: it fixes atmospheric nitrogen through root nodule bacteria, reducing the need for supplemental fertilizer, and it sustains pollinator populations through bloom periods when pear flowers need consistent bee activity for fruit set.

White clover (Trifolium repens) is the most common choice for orchard understories. It tolerates mowing, stays low enough to avoid competing with tree trunks for light, and reseeds reliably. Red clover grows taller and can become weedy if not managed. Either type should be kept back from the trunk drip line to reduce moisture retention against the bark.

This pairing works best in established orchards where trees are not competing intensely for resources. In young plantings (first two to three years), clover can compete with shallow feeder roots during dry stretches. Mow or suppress clover within 18 inches of young trunks until the root system is well established.
