The cashew plant (Anacardium occidentale) is a tropical evergreen tree native to Brazil but now cultivated in many parts of the world, including India, Vietnam, Nigeria, and the Philippines. Known for producing the beloved cashew nut, the cashew plant also yields the cashew apple, a juicy, pear-shaped fruit.
Understanding how the cashew plant grows and its wide range of uses can help both home gardeners and agricultural investors capitalize on this versatile crop.
How the Cashew Plant Grows
The cashew plant thrives in tropical climates, requiring well-drained, sandy soil and plenty of sunlight. Here are key growth requirements:
Climate: Warm temperatures (24–28°C)
Soil: Sandy or loamy, with a pH of 5–6.5
Water: Drought-tolerant but benefits from moderate irrigation during dry spells
Harvest Time: 3–5 years after planting for initial yield, with peak production at 7–10 years
The tree can grow up to 14 meters (46 feet) but is often pruned to a manageable height in commercial farms.
Cashew Nut vs. Cashew Apple
The cashew nut grows outside the fruit, enclosed in a hard shell containing toxic oils. The cashew apple, on the other hand, is bright red or yellow and rich in vitamin C. While the nut is widely consumed globally, the cashew apple is used locally for juices, jams, and even alcoholic beverages.
