Why do redwoods grow so tall?
The trees grow tall for the following reasons: large amounts of rain (60-140 inches per year), mostly from February–May; summer fog which reduces evapotranspiration; temperate climate, average temperatures between 45 degrees and 61 degrees Fahrenheit; rich soil in river bottom flats; few natural enemies; burl sprouts (see following question), which promote growth after injury by fire or toppling; wind protection by other redwoods.
