Strategy

First 14 to 16 months: Concentrate on growing a vigorous, healthy pineapple plant for the first 14 to 16 months. Fertilize in small amounts frequently (every 6 to 8 weeks) and water during dry periods.

After 16 months, induce flowering or allow winter cool period to induce flowering; reduce nitrogen fertilizer rate. Once flowering occurs, continue to fertilize and water plants to enhance fruit growth and quality.
