In commercial blueberry fields containing both velvetleaf and late low blueberry, yields are often lower than in fields made up of only late low blueberry. Cross pollination apparently results in reduced fruit set. Seeds can germinate on mineral or organic soils when moisture and aeration are adequate. Seed dispersal by various birds and mammals. The American robin is a particularly effective dispersal agent.
Fruit typically ripens just as birds are preparing for seasonal migrations.
Seedling establishment typically slow wherever significant competition is present. Berry production fluctuates annually according to the genetics of the individual clone, weather conditions, and insect availability. However, fruit production is often good and nearly all berries contain some viable seed. Pollinators are required for good fruit set and dry, warm weather during flowering generally results in more active insect pollinators and better fruit set. Late spring frosts can greatly reduce fruit production.
