Cashew Trees are extremely easy to grow, but that is where the straightforward nature of this unique tree ends. The Cashew, more than any other widely consumed nut, is far more than it appears. Most nuts are simply tree seeds, but Cashew Nuts are the seed and the fruit. The Cashew Apple, which appears above each Cashew Nut, is actually the swollen stem end of the branch where each nut grows. The bright red, juicy Cashew Apples are sweet and edible. With care you can also harvest your own Cashew Nuts from the Cashew Tree.
Cashew Trees can be grown in the ground in USDA Zones 9 to 11. You can also grow a Cashew Tree in a container if you are limited on space, or live in Zones 4 to 11. Mature Cashew Trees will reach a height of 12 feet, and a width of about 15 feet. They are self-fertile, prefer full to partial sun, and are fast growing.
Please Note: Cashews themselves aren’t toxic, but they are surrounded by a shell that consists of the toxic oil urushiol. Coming into contact with urushiol can cause itching, blisters, and skin rashes. Please handle with care.
