How to Feed Pineapple Plants

Overview

After eating a pineapple, don't throw away the top or toss it in the compost pile. Place the top of a pineapple on high-quality potting soil to grow a new pineapple. Pineapple plants are slow-growers, though, and typically not ready to harvest and eat for at least a year. Feed your pineapple plants properly to help the pineapple grow and develop.

Step 1

Wait until the pineapple top starts producing new leaves before feeding the plant. This usually takes approximately four weeks. During these four weeks, water the plant when the top 1 inch of soil feels dry to the touch.

Step 2

Mix a water-soluble fertilizer formulated for houseplants according to the manufacturer's directions.

Step 3

Pour the fertilizer mix over the leaves of the propagule (pineapple top) once a month for the first six months. According to Texas A&M University, it takes the propagule 6 months to develop a proper root system and the plant benefits from having the leaves directly fertilized.

Step 4

Pour the fertilizer mixture directly onto the soil instead of on the leaves after the plant's first 6 months. Continue fertilizing the plant monthly until it is time to harvest.

Step 5

Cut off the top of the pineapple before you eat the fruit, and start the process over again.
