These small trees or large spreading bushes are known for their tropical-looking foliage and pear-shaped edible fruits. In colder regions, they are grown as tub plants, taken inside, or protected during the winter. They grow in most soils and are drought-resistant once established. Plant where fruit drop will not cause a litter problem. In cooler areas, plant near or against a south wall that retains heat. Plant in wire baskets if gophers are a problem. Prune to almost any shape and size. Trees bear fruit twice a year without pollination. Fertilize and water regularly for best fruit production. Protect fruit from birds.
