Prune roots of non-woody plants before planting: freshwater wetlands
Overall effectiveness category No evidence found (no assessment)
Number of studies: 0
Background information and definitions
Plants can be stressed by the process of planting into a new site. Pruning before planting can encourage the growth of new, nutrient-assimilating feeder roots close to the plant: within the zone of roots that will be moved with the plant (Swackhamer & Sellmer 2007). It can also make planting process quicker and easier (Allen & Kennedy 1989).
To be summarized as evidence for this action, studies must have explicitly compared the performance of pruned and unpruned plants. Studies that simply report the performance of pruned plants are not summarized here. Studies do not have to be in flooded/saturated soils, as long as they involve wetland-characteristic species.
