Water sprouts are similar to suckers, but they emerge from tree trunks and older branches, rather than from underground.
Water sprouts, also called gourmands, grow vigorously and often seem to appear overnight. They use large amounts of water and nutrients and provide no benefit. Like suckers, water sprouts are structurally unsound and highly prone to pests and disease.
Water sprouts may still produce fruit, but that fruit is generally of poor quality and reduced quantity. Water sprouts often emerge after pruning or other damage and they should be removed as soon as they are seen.
You can grow a surprising amount of food in your own yard. Ask me how!
