How to prune lonicera japonica

Early spring before new growth emerges; a second light tidy after the main June flush. Cut back the entire plant by one-third to one-half in spring using loppers or shears, removing the oldest, woodiest stems to the base. After flowering, shear lightly to remove spent growth and stimulate a second flush.

Annually (hard spring cut); additional shearing after flowering as needed. Lonicera japonica (Japanese honeysuckle) is a rampant semi-evergreen climber that can become invasive if unpruned. Prune hard each spring to remove the previous year's tangled growth and keep it within bounds. In many US regions it is considered invasive — check local regulations before planting.
