Black Raspberry + Garlic

Black raspberries are unusually susceptible to mosaic virus and other aphid-vectored diseases, which makes aphid suppression a higher priority here than with red raspberries or blackberries. Garlic's sulfur compounds are thought to repel aphids and may reduce colonization pressure on nearby canes. Plant garlic cloves in fall, 6 to 8 inches from the drip line of established raspberry rows, so bulb development doesn't compete with spring cane growth. Both crops tolerate slightly acidic, well-drained soil (pH 6.0 to 6.5), so fertility management aligns reasonably well. The pairing is most useful in plantings with a history of aphid pressure or in regions where Raspberry mosaic virus is common. It is less relevant in new, clean plantings or where aphid populations are reliably low. Garlic harvest in early summer also leaves the ground open before black raspberry peak harvest, minimizing harvest interference.
