Increased fine root damage was followed by increased compensatory root growth. Short and long root production and longevity decreased, and mortality increased by soil Fr, while there were no significant effects of WL. The starch content of leaves was temporarily higher in Fr than NoFr in the latter part of the growing season.

Physiological activation (dark-acclimated chlorophyll fluorescence and chlorophyll content index) and growth of leaves and shoot elongation and stem diameter growth started earlier in Fr than NoFr (soil not frozen). Using a whole-tree approach, we studied the responses of silver birch ( Betula pendula Roth.) saplings, growing in mineral soil, to 6-week Fr and WL in factorial combinations during dormancy, with accompanying changes in soil gas concentrations. This may expose tree roots to waterlogging (WL) and soil freezing (Fr) more than in the current climate and therefore affect tree growth and survival. ItвЂ™s best not to prune a paper birch unless absolutely necessary because it attracts insects and the tree bleeds copious amounts of sap when cut.Winter precipitation and soil freezeвЂ“thaw events have been predicted to increase in boreal regions with climate change. You can also help the tree resist birch borers by fertilizing annually in spring and using organic mulch. If you live in an area where these insects are a problem, try planting a resistant cultivar such as вЂSnowy.вЂ™ Paper birches are susceptible to a number of insects, including the destructive bronze birch borers. It prefers long winters and mild summers. The trees adapt to most types of soil as long as it is cool in summer.

Plant them in a location with full sun and moist but well-drained soil. Paper birches transplant easily with little shock. Although the roots are shallow, they donвЂ™t usually rise above the surface of the soil, so you can use them as lawn or roadside trees.Use paper birches to transition gradually from woods to open ground.Their thin canopy lets you grow other plants beneath them. Grow them in groups in moist beds and borders.Here are a few uses of paper birch in the landscape: They also attract a number of birds, including yellow bellied sap suckers, black-capped chickadees, tree sparrows and pine siskins. Paper birch trees are a larval host for luna moth caterpillars. Most specimens have bright-colored fall foliage. In spring, it produces hanging clusters of catkins that are very attractive when in bloom. The treeвЂ™s most striking feature is its peeling white bark, which is highlighted with streaks of pink and black. Paper birch trees grow as much as 60 feet (18 m.) tall and 35 feet (11 m.) wide, adding as much as 2 feet (61 cm.) per year in USDAВ plant hardiness zones 2 to 6 or 7 where winters are cold.

Growing paper birch trees means youвЂ™ll always have something interesting to look at in the landscape. The lowest branches are just a few feet (91 cm.) off the ground, and in fall the foliage turns a blazing shade of yellow. They have a single trunk, but nurseries like to grow them in clumps of three and call them вЂњclumping birches.вЂќ Paper birch trees ( Betula papyriferia), also called canoe birches, are native to moist stream banks and lakesides in Northeastern United States and Canada. Despite these drawbacks, they are well worth growing for their beautiful bark that shines against a dark background. Although they love cool climates, the branches break easily on windy days, especially when weighted down with snow and ice. Unfortunately, paper birches donвЂ™t fare well in the city where they struggle to survive in the face of pollution, heat and dry conditions. Their narrow canopy produces dappled shade that makes it possible to grow these trees in a sea of groundcover plants such as wintergreen and barberry, and you can even grow grass under them. Native to northern climates, paper birch trees are lovely additions to rural landscapes.
