Effects of Root-Coating With the Polymer Waterlock on Survival and Growth of Drought-Stressed Bareroot Seedlings of White Spruce (Picea glauca (Moench) Voss) and Red Pine (Pinus resinosa Ait.)

Root coating with a superabsorbent polymer is a recommendable precautionary measure against drought-induced mortality in areas with frequent dry spells during the planting season. Root-coated white spruce (Picea glauca (Moench) Voss) exposed to no more then 2 weeks of post-planting drought showed a significant improvement of 24 percent in survival as compared to untreated seedlings. Root coating had not significant effect beyond 2 weeks of drought.
