How to prune madagascar periwinkle (vinca)

Tip-pinch at planting out in late spring; light mid-season trim if leggy. Pinch out the growing tip of each stem to just above a leaf node at planting time to encourage branching. If the plant becomes leggy mid-season, cut back by one-quarter to one-third to a leafy node — new growth and fresh blooms follow within 3–4 weeks.

Tip-pinch once at establishment; mid-season trim as needed. Madagascar Periwinkle benefits from light tip-pinching when young to encourage bushy growth and better bloom coverage. Deadheading is optional — the plant is largely self-cleaning. A modest trim mid-season can rejuvenate a leggy plant. It is typically grown as an annual, so hard pruning for longevity is rarely necessary.
