Growing Conditions for Karambola
Karambola trees thrive in warm, tropical climates and require well-drained soil to flourish. They prefer full sun exposure and are sensitive to frost, making them unsuitable for colder regions. The trees can grow up to 30 feet tall and typically begin to bear fruit within three to four years of planting. Regular watering and fertilization are essential for optimal growth and fruit production.
