DescriptionAnnual and biennial fires applied around May 1 are more beneficial to the growth of young longleaf pines than March 1 fires. Four years of testing on a poorly drained silt loam soil in central Louisiana showed that more grass-stage seedlings survived. began height growth, and grew taller on plots burned in May than on March-burned plots. A biennial May burn was best for survival and initial height growth of grass-stage seedlings. Annual May fires favored growth of older seedlings and were more effective in the control of brown-spot needle blight.
