Description

• The dragon fruit tree is actually a type of cactus vine, which can reach up to 20 feet long or tall -- depending on support structure. The flowers of the dragon fruit bloom only at night, producing white or pink bell-shaped buds that can reach 14 inches long. The fruit itself is often red and features red or yellow scales on the exterior, giving the fruit its name. The interior of the fruit can be white, red or deep magenta. The vine also produces small, black seeds embedded in the pulp of the fruit, which can be used to propagate the plant.
  
  

Uses

• The dragon fruit itself is eaten in a variety of applications. It can be eaten directly from the vine for a fresh, fruity taste. The fruits are also often frozen and eaten cold, or used to make ice cream, frozen yogurt, jelly or jam, juice and candy. The pulp and juice are commonly used to flavor pastries and mixed drinks as well. Unopened flowers can be cooked and eaten like a vegetable; they are not generally eaten raw. The seeds are edible as well, but in large quantities have a laxative effect.
  
  

Climate

• Native to the tropical areas of the world, dragon fruits can tolerate temperatures up to 104 degrees Fahrenheit. Any more than a brief exposure to freezing temperatures (32 F or lower) will damage the plant, leading to stunted growth, dropped buds and fruit and potentially death. These vines grow best in four to five hours of full sunlight each day, with a trellis system that allows it to grow up out of the dirt. Dragon fruit thrives in soil that is enriched with organic material for better drainage and fertility.
  
  

Care

• As soon as the dragon fruits begin to grow blooms, fertilize with 1/4 lb. of balanced palm fertilizer, and repeat application every two weeks during the growing season to promote fruit production and repeated blooms -- sometimes up to six per season. The plant responds well to slightly dry conditions, since it is a cactus, and can need as little as 20 inches of rainfall per year. Water only if your area suffers from drought during the summer. Adding a 4- to 6-inch layer of organic mulch around the base of the plant will reduce the need for extra watering even more by insulating the soil to help it retain moisture.
