Care Guide
Watering
Water regularly during the first year to establish a deep root system. Once established, periwinkle is moderately drought-tolerant but performs best with weekly watering during dry spells.
Sunlight
Prefers partial to full shade. While it can tolerate full sun in cooler climates, intense afternoon sun can scorch the leaves.
Soil and Fertilizer
Grows best in moist, well-draining soil rich in organic matter. Apply a balanced slow-release fertilizer in early spring if growth is sluggish.
Pruning
Prune back in early spring before new growth starts to control spread and encourage bushier foliage and more blooms.
Propagation Methods
Cutting
Take stem cuttings in summer, dip in rooting hormone, and plant in moist propagating mix.
Division
Divide established clumps in spring or autumn and replant immediately.
