In general, trees suffering from replant disease show slow and uneven growth within the first three years of planting (A). Both specific (e.g., apple after apple) and non-specific (e.g., stone fruit after vegetables) replant disorders are known. The disorder is characterized by reduced shoot growth, severe stunting, rosetted leaves, and reduced fruit production. The root systems of affected trees are fibrous, poorly developed and are often in a state of decay.
