Add lime to the soil after tree planting
A replicated, randomized, controlled study in 2004-2009 in temperate broadleaf forest in Pennsylvania, USA (Long, Brose & Horsley 2012) found no effect of lime addition on the growth of planted seedlings of northern red oak Quercus rubra. Seedling height (16-33 cm) and root-collar diameter (6.5-9.5 mm) were similar between treatments. Data were collected in 2009 in two plots (12.5 × 8.5 m) of each treatment: 0, 4.5, 9.0 and 13.5 x 103kg /ha lime application rates (applied in May 2004) at each of five sites. All plots were partially thinned (shelterwood harvest) within the past 12 years and were planted with northern red oak seedlings in April 2004.

Fence to prevent grazing after tree planting
A replicated, randomized, controlled study in 2004-2009 in temperate broadleaf forest in Pennsylvania, USA (Long, Brose & Horsley 2012) found that deer exclusion increased the size of planted northern red oak Quercus rubra seedlings. Seedling height (fenced: 33 cm; unfenced: 16 cm) and root-collar diameter (fenced: 9.5 mm; unfenced: 6.5) were higher in fenced plots. Data were collected in 2009 in four fenced (2.4 m tall wire to exclude deer in 2002-2004) and four unfenced plots (12.5 × 8.5 m) at each of five sites. All plots were partially thinned (shelterwood harvest) within the past 12 years and were planted with northern red oak seedlings in Apr 2004.
