A tree's fruit increases in quality by one star per year of tree age after reaching maturity. Fruit trees will produce silver star fruit after one year, gold after two years, and iridium after three. Once the tree is fully grown, the surrounding area does not need to be kept clear for the tree's fruit to increase in quality. | A tree's fruit increases in quality by one star per year of tree age after reaching maturity.
