Production Cycle Vaccinium angustifolium has a two year production cycle. The first year is known as the vegetative year and the second is known as the fruit-bearing year. In order to be productive each year, most farmers divide their land to have half their crop in the vegetative year while the other half is in the bruit-bearing year. Pruning Native Americans regularly burned away trees and shrubs in parts of eastern Maine to stimulate blueberry production. Modern farmers use various methods of burning or mowing to accomplish this. There are several methods growers use to stimulate blueberry production on their land, such as burning the land or using a flail mower, bush hog, lawnmower, etc. to cut the plants off as close to the ground as possible without scalping the land. These procedures are used to promote the spreading of rhizomes under the soil. Some growers use a sickle bar mower in the fall after the crop has been harvested to mow the plants off, leaving roughly 1 to 2 inches of stem so the growers can then burn the remainder of the plants in the spring, using less fuel for the fire. Farmers then treat their crops with pesticides to control weeds and insects. The fields are then left for new growth to emerge, develop, and flourish for the remainder of the year. Pollination During the harvest or fruit bearing year, blueberry growers rent honey bee hives to put in their fields for pollination. These hives are placed in the fields at a density range of anywhere from 1-8 hives per acre. The hives are placed in the fields at 10-20% bloom allowing the bees to have enough forage rather than going elsewhere to forage. Hives are left in blueberry fields for 2 weeks on average, allowing the bees to pollinate the variety of clones in the field, all of which bloom at different times during the two-week period. Some growers also use bumble bees as well in hopes of maximum pollination. Bumblebees will fly in colder
