Water: Water your groove-leaf sugarbush every couple of weeks during dry spells, or weekly if newly planted. For container-grown groove-leaf sugarbush, allow the soil to dry slightly between waterings to prevent root rot.

Pruning: Groove-leaf sugarbush requires early spring pruning to maintain shape and health. Remove dead branches and thin overcrowded areas for air circulation. Avoid cutting old wood to ensure flowering. Regular pruning promotes vigorous growth and enhances the plant's aesthetic appeal.

Propagation: Propagate groove-leaf sugarbush using cuttings instead of seeds. Take cuttings from last year's side branches in spring or fall. Remove the bottom 2/3 leaves, dip in rooting hormone, and plant in a half sand, half peat moss mix. Keep moist and shaded; rooting takes up to 6 weeks.
