The story
Robusta coffee grows wild in the forest understory from Guinea to Uganda and was domesticated in Central Africa. It is tougher and more caffeine-rich than arabica and now makes up much of the world's coffee.
Planting
Light shade under taller trees, deep, moist, slightly acid soil, warm and humid all year. Grow from seed or a nursery plant; it needs cross-pollination, so plant more than one.
Growing
Mulch with leaves, prune old stems every few years, and keep it under shade trees.
Harvest and use
Cherries ripen red in the dry season; pick, pulp, dry and roast the beans.
What to watch for
Frost kills it. Plant two or more for a good crop.
