The Pepper Tree requires no watering once established. Generally, trees need supplemental irrigation to get established, especially if planted after the rainy season. During the first year, irrigate in the amount of 20 – 25 liters of water twice a week. During its second year, a tree needs to be irrigated in the amount of 40 liters once a week. Beginning with the third year, trees usually get established, and some, like the Pepper Tree, do not require any supplemental irrigation. Overwatering of the Pepper Tree leads to chlorosis (yellowing of leaves), and branch growth that is prone to breakage.
