Invasive potential *

Mites, scales, and mealy-bugs can be serious pest problems; no diseases are of major
Raccoons, squirrels, and opposums will sometimes feed on maturing pineapple fruit
The spines along leaf margins and the stiff point at the leaf apex can cause mechanical injury 3
When unripe, the pineapple is not only inedible but poisonous, irritating the throat and acting as a drastic purgative. Excessive consumption of pineapple cores has caused the formation of fiber balls (bezoars) in the digestive tract. 4

Pineapple has apparently been cultivated by indigenous people of the tropical Americas and the Caribbean Region for thousands of years. New World explorers then distributed pineapple during the 1500s to 1700s to new areas including Europe, Africa, and Asia. The commercial export trade began during early 19th century from the West Indies. This led to further commercial development of in the Caribbean during the mid-19th century. However, with the improvement in refrigerated sea transportation by the end of the 19th century, production shifted to Hawaii, Asia, and Africa. In the U.S., Puerto Rico and Hawaii have moderately large and important industries. Pineapples are not grown commercially in Florida but are common dooryard yard plants in warm locations throughout the state. The first recorded introduction of pineapple into Florida was in 1860. 1
The pineapple is a herbaceous perennial with long sword-like leaves arranged in a spiral around a central stem and a terminal inflorescence. Leaves may or may not bear marginal spines depending upon variety and cultural practices. Adult plants may be 3 to 6 feet (0.9-1.8 m) high and wide. 1
The leaves are sessile and whorled around a central stem. They increase in size toward the top of the plant. Individual leaves range in length from 2 to 8 inches long (5-20 cm) for new plants and up to slightly more than 5 feet long (1.5 m) on mature, healthy plants. Leaves taper progressively toward the tip and end in a sharp point. Leaves may or may not have spines along their edges depending upon variety and growing conditions. The leaves are semi-rigid and allow the plant to collect water at the base of the leaves, where aerial roots may absorb water and nutrients. Once the plant has produced between 70 and 80 leaves it is ready to flower. 1
The fruit peduncle (stem) and inflorescence develop from the apical growing point. The emergence of the inflorescence is called the red heart stage due to the reddish peduncle bracts at the base of the inflorescence. The inflorescence consists of from 50 to over 200 individual flowers and is capped by a crown of numerous short leaves (up to 150).
The individual flowers are hermaphroditic with three sepals and petals, six stamens and one pistil. The flower petals are white at their bases to violet-blue at their tips. Each flower is surrounded by a hairy bract.
Generally the first flowers open 50 or so days after flower induction and flowering continues for 20 to 40 days. Usually one to 10 flowers open daily beginning around midnight and close the following evening
Pineapple plants are self-incompatible, meaning pollen from the same variety will not result in seed production and seedy fruit. However, growing several varieties next to each other and flowering simultaneously may result in seedy fruit. To prevent seed formation, either grow only one variety or induce flowering at different times. 1
Forcing a Pineapple to Flower
The fruit of pineapple is a seedless syncarp. A syncarp is a fruit derived from the fusion of many individual flowers into one fruit (Fig. 3. The fruit consists of the fused ovaries, bases of sepals and bracts, and cortex of the central core. When fruit are mature (ready to pick), the individual fruitlets flatten and the peel color begins to change from green to yellow progressively from the base to the top of the fruit. Fruit may weigh up to 5 lbs (2.3 kg) or more. Ripe fruit have a yellow peel and pleasant aroma. The pulp is yellow to golden yellow, sweet, and juicy. 1
The time from planting to harvest depends upon the cultivar, cultural practices, and temperature; it ranges from 18 to 24 months. 1
Pineapple plants grow best in moderately fertile, sandy loam soils of neutral to mildly acid pH. Plants will grow satisfactorily in sandy and calcareous soils with attention to watering and fertilizer. Pineapple should be grown in well-drained soils and areas of the landscape that do not flood. 1
How to Grow a Pinneaple
Dry fertilizer mixtures containing 6 to 10% nitrogen (N), 6 to 10% available phosphoric acid (P), 6 to 10% potash (K), and 4 to 6% magnesium (Mg) give satisfactory results with pineapple plants. Pineapple plants may also be fertilized foliarly with mild solutions of nutrient mixes that include NPK and Mg. Foliar sprays containing micronutrients such as zinc and manganese (iron is also sometimes a component) should be applied 2 to 3 times a year during the warm season. 1
Fertilizer Recommendations from the University of Florida
Pineapple plants should be watered during extended dry periods for best plant growth and fruit production. 1
Pineapple may be used fresh, juiced, dried, made into candies, and incorporated into cooked dishes and desserts. 1
The pineapple does not lend itself well to freezing, as it tends to develop off flavors. 4

Folk Medicinal Uses **
Pineapple juice is taken as a diuretic and to expedite labor, also as a gargle in cases of sore throat and as an antidote for seasickness. The flesh of very young (toxic) fruits is deliberately ingested to achieve abortion (a little with honey on 3 successive mornings); also to expel intestinal worms; and as a drastic treatment for venereal diseases. In Africa the dried, powdered root is a remedy for edema. The crushed rind is applied on fractures and the rind decoction with rosemary is applied on hemorrhoids. Indians in Panama use the leaf juice as a purgative, emmenagogue and vermifuge. 4
The pineapple fruit with crown intact is often used as a decoration and there are variegated forms of the plant universally grown for their showiness indoors or out. Since 1963, thousands of potted, ethylene treated pineapple plants with fruits have been shipped annually from southern Florida to northern cities as indoor ornamentals. 4
Pineapple juice has been employed for cleaning machete and knife blades and, with sand, for scrubbing boat decks. 4
