ENVIRONMENTAL FACTORS

Found in wild marshes, bogs and along ditch edges. Easily invades older, established cranberry beds. If not restricted, bog rosemary can form large dense patches and compete with cranberry vines for sunlight and nutrients.

SCOUTING PROCEDURE/ET

While scouting a cranberry bed for disease and insect pests, identify weed populations as they arise. Note the specie(s) of weed present as well as the population level relative to field area. Example: 15% bog rosemary, 30% boneset and joe-pye weed mix.
