Very good for edges and mounds. Grows 4â-6â per year. Zone 4-9 Buxus Sempervirens 'Rotundifolia' Fastest growing boxwood, 9-12 per year. Extremely nice for hedges and topiary.
Never fertilize a boxwood in late summer, however, as this can encourage late growth that can be damaged by frost. You can fertilize newly planted boxwood in late fall, if necessary, to promote root growth. Boxwood requires specific soil pH -- between 6.5 an 7.2 -- to properly utilize fertilizer. To increase soil pH below this level, add dolomitic lime, which should keep the pH at the correct level for four to seven years.
