Guavas grow best in hot areas which do not get frost. They can, however, grow in most places where the winters are not too cold. If they are planted where there is a little frost, the young trees must be covered.
Guava is a fast growing evergreen shrub or small tree that can grow to a height of 3-10 m. It has a shallow root system. Guava produces low drooping branches from the base and suckers from the roots. The trunk is slender, 20 cm in diameter, covered with a smooth green to red brown bark that peels off in thin flakes.
