Soak non-woody plants before planting: brackish/saline wetlands
Overall effectiveness category No evidence found (no assessment)
Number of studies: 0
Background information and definitions
Soaking vegetation before planting might increase tissue water content, promote root growth and increase survival after planting (Pezeshki et al. 2005). An abundance of roots might help the planted vegetation to take up enough water during dry periods. Adventitious roots may grow from the stem, near the water line, and help with oxygen uptake if the site is flooded or saturated (Havens 1996). Studies do not have to be in flooded/saturated soils, as long as they involve wetland-characteristic species.
To be summarized as evidence for this action, studies must have explicitly compared the performance of soaked and unsoaked 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.
