Waterlogging of plants can occur if there is too much water in the growing medium, due to poor soil structure, compaction, insufficient drainage or overwatering. Plant roots become asphyxiated in waterlogged soil, causing leaves to turn yellow, plants to wilt, bark to peel off branches, roots to rot, and the eventual death of the plant. Waterlogging can also slow down the process of soil warming in spring and as a result, plants may be slow to make strong growth.

Control

Improve drainage by regularly digging in plenty of organic matter to improve the soil structure. Grow moisture-loving plants in sites particularly prone to waterlogging, or consider using raised beds. Make sure that container-grown plants have sufficient drainage holes, and that they do not become blocked with debris.
