Make money from tree tomatoes
... Tree tomato is a small, half woody plant with shallow roots. It grows to an average height of 3.5 - 5.0 m depending on the variety. It produces an egg-shaped oval fruit. The fruit tree prefers welldrained soils and grows best in climates with long hours of sunlight. In hot and dry climates, the tree ...
