Apricot and Tansy

Tansy (Tanacetum vulgare) planted beneath or near apricot trees can reduce aphid colonies and Japanese beetle activity through its aromatic compounds. The pairing works best when tansy is established along the drip line or within 3 to 6 feet of the trunk, close enough that volatile oils reach the canopy without tansy's aggressive spreading habit crowding the root zone.

Tansy spreads readily by rhizome and self-seed, so cutting it back before it sets seed each year keeps it from becoming a maintenance problem. It tolerates a wide range of soils but performs in the same well-drained, moderately fertile conditions apricots prefer. In heavier soils prone to wet winters, both plants may struggle.

This pairing is most useful during peak aphid pressure in late spring and early summer, and during Japanese beetle flight from late June through August. It is not a substitute for monitoring or intervention when pressure is heavy; consider it one element of a broader IPM approach rather than a standalone control.
