The berries are very small and have to be picked by hand and hand harvesting of highbush blueberries is labor intensive and requires as many as 1150 hours of labor per hectare.
To get the highest quality berries, harvest 4 to 6 days after the berry turns completely blue. If picked earlier, the berries will not be as large and the flavor will not fully developed.
Over the row, self-propelled vibrating machines have been developed for harvesting blueberries. The use of mechanical vibratos nearly triples worker productivity and reduced harvesting cost by 55%.
Even though the picking cost is lower for mechanically harvested fruit, more berries are picked per hectare by hand and they have a higher value.
Harvesting blueberries, low bush blueberries like there are in Maine, was accomplished using a tool called a rake. A rake is an odd shaped tool that has a handle. Low bush blueberries require the harvester to get drown to ground level.
Mixtures of soft ripe and hard ripe fruits should be avoided as the over-ripe ones can speed deterioration.
