Some plant patches produce berries with median diameters of one centimeter or better.
Fruit set can be so heavy that the ground seems pink.
Starting in 1996, Roundup in water has been used in experiments aimed at such techniques. Blueberry was destroyed on all sites with the 10x10-foot areas reduced to small forests of leafless brush. Established Patches Several lingonberry patches have been observed and mowed for some time. Competing vegetation in Spruce, Orchard and Highway1 patches was mowed for several years with the result that each patch became many times larger. Highway2 received similar treatment beginning in 1995.
