Habitat & Ecology

Himalayan Blackberry is found along disturbed roadsides and are prevalent in ditches. It can adapt to a wide range of moisture and soil regimes but thrives in moist areas with full sunlight.


This plant spreads aggressively and can take over large areas of riparian areas and outcompete native vegetation. Dead stems and leaf litter build-up does not allow other plants to grow. Birds and animals eat the berries and spread the seed kilometers away. One


Mechanical control like pulling canes, digging and mowing will need to occur a number of times. Mechanical control can often leave root buds and roots behind and will re-sprout. Prevention is best for this plant. Choose a native blackberry for your garden. Contact LRISS for all other treatment questions.
