Harvest
Long used by native peoples, wild Camu camu fruit is harvested directly into canoes. The fruit has only recently come into large-scale cultivation and sale to the world market with Japan being the major buyer. It is relatively easy to cultivate. It survives best in hot, damp tropical climates but will grow in the subtropics, surviving temperatures down to just above freezing. It requires copious water. Fair trade is present in low-land production from the Association of Camu Camu Producers of the Peruvian Amazon.
The tree occurs in locally dense populations (1000/ha) or even monospecific stands in Amazonian flood plains and riparian vegetation. The plant is extremely tolerant of flooding, withstanding 4 to 5 months with the roots and even much of the aerial parts submerged in water. The species propagates through seeds. In cultivation, the tree begins bearing fruits after attaining 2 cm in stem girth (three years after emergence of the seedling). Plants flower at the end of the dry season and fruit at the peak of the rainy season. Observations with both wild and cultivated plants suggest that trees can remain productive for several decades.
Wild trees have been found to yield 12 kg of fruit on average. At suggested planting densities of 600–1100 trees/ha, about 12 t fruit can be derived in cultivation from one hectare. However, with improved horticultural techniques, such as the use of clonal elite material, pruning and fertilization, much higher yields could be achieved.

Famous quotes containing the word harvest:
“The harvest is plentiful, but the laborers are few...”
—Bible: New Testament, Matthew 9:37.
“They may bring their fattest cattle and richest fruits to the fair, but they are all eclipsed by the show of men. These are stirring autumn days, when men sweep by in crowds, amid the rustle of leaves like migrating finches; this is the true harvest of the year, when the air is but the breath of men, and the rustling of leaves is as the trampling of the crowd.”
—Henry David Thoreau (1817–1862)
“It is in these acts called trivialities that the seeds of joy are forever wasted, until men and women look round with haggard faces at the devastation their own waste has made, and say, the earth bears no harvest of sweetness—calling their denial knowledge.”
—George Eliot [Mary Ann (or Marian)
