Acca Sellowiana - Cultivation

Cultivation

Some grafted cultivars of feijoa are self-fertile. Most are not, and require a pollinator. Seedlings may or may not be of usable quality, and may or may not be self-fertile. Feijoas will mature into a sprawly shrub, but can be kept successfully as a large container plant, though accommodations will need to be made for the width of the plants, and the need to encourage new growth for fruit production. They can succeed in greenhouses in temperate parts of the United States, and have been grown in-ground as fruiting trees on the United States east coast in coastal Georgia and South Carolina as well as in California. Other regions of the United States: the Pacific Northwest, the southernmost Appalachian Mountains, and the immediate coastal region from North Carolina to Delaware all would warrant further investigation.

In California, robins, mockingbirds, hummingbirds, starlings, scrub jays, towhees, and grey squirrels feast on the petals and are presumed to be assisting with pollination. Honeybees also visit the flowers.

In the South Caucasus, feijoa was cultivated in the southern coastal region of Azerbaijan since 1928; cultivation in the neighboring Georgia has gradually increased to about 988 hectares in 1986.

In New Zealand, the pollinators of this plant are bees, bumblebees, and medium-sized birds. The silvereye is a pollinator in the cooler parts of the South Island; the blackbird and the Indian myna, which feeds on the sweet, fleshy flower petals, are pollinators further north.

In some areas where the species has been introduced, however, the trees have been unproductive due to lack of pollinators. The shrub has very few insect pests.
