The pineapple plant is an interesting, if not strange plant to have around the house. The long, sword-shaped leaves grow in a spiral out from the center. After three to five years, a tiny pineapple emerges from the center of the plant. It balances on a long stalk until it reaches maturity. Planting pineapples from seed is a long and often difficult process. The seeds do not germinate easily and it takes the plant a particularly long time to reach maturity. Seeing your pineapple plant thrive makes all the hard work worth it.
Fill a 6-inch pot with rich seed-starting potting soil. Moisten the soil until it is evenly damp.
Nick the seed using a sharp razor knife. You want to just barely break the surface so that moisture can penetrate and start germination.
Make a 1/4-inch deep hole in the center of the potting soil. Lay one seed into the hole and cover it.
Drive a 8- to 12-inch bamboo stake into the side of the pot. Place a clear plastic bag upside down over the pot and secure the opening around the rim of the pot.
Put the pot in a sunny windowsill or humid bathroom. The temperature must remain above 75 degrees F for the seed to germinate.
Water the soil every three to four days to keep it moist. Germination takes four to six months. Transplant to a larger pot when the seedling is 2-inches tall.
