Many plants thrive wonderfully in a pitcher of water as opposed to a pot of soil, which can require too much maintenance for some inexperienced growers. Plants such as potatoes, onions, garlic and a variety of herbs grow well in pitchers as decorative and even culinary plants in a kitchen windowsill or other well-lighted location. Pitcher-growing in your home is a simple and brief process.
Fill the glass pitcher about three-quarters full with water.
Push a toothpick into each side of the potato.
Drop the potato into the glass pitcher. If the toothpicks are in the potato properly, they will hold the potato halfway in the water.
Keep only half of the potato submerged in the water. Eventually, vines will sprout from the eyes of the potato.
Place the pitcher in a sunny windowsill or on your dining room table as a decorative and green vine.
