Guava

Guava is a true tropical that won't survive the lightest frost, which makes a productive guava tree one of the more improbable things a Growing Dome makes possible. The dome's thermal mass and steady warmth give the tree the heat and humidity it needs to flower and fruit, even in places like Colorado, Maine, or Alaska where the plant has no business surviving. Owners are pulling fresh guavas off shrubs and trees that should have died their first winter, getting a fragrant, vitamin-C-loaded harvest most of North America has to import. Explore placement near the dome's pond and thermal mass, the multi-year timeline from young tree to first fruit, pruning to shrub or tree form, managing scale and aphids, and stories from owners on dome guava trees and the fruit they've produced.
