How to Grow Periwinkle Plant Outdoors

Periwinkle, also known as Vinca minor, is a versatile and low-maintenance plant that can add a touch of beauty to any outdoor garden. With its vibrant blue or purple flowers and glossy green leaves, periwinkle is a popular choice for ground cover or container planting. Whether you are a beginner gardener or an experienced one, growing periwinkle outdoors is relatively easy. In this article, we will guide you through the steps of growing periwinkle plant outdoors.

Choosing the Right Location

The first step in growing periwinkle outdoors is choosing the right location. Periwinkle prefers partial shade to full shade, although it can tolerate some sun in cooler climates. It thrives in well-drained soil that is rich in organic matter. Before planting, prepare the soil by removing weeds and adding compost or well-rotted manure to improve its fertility.

Planting Periwinkle

Periwinkle can be grown from seeds, cuttings, or nursery-bought plants. If you are starting from seeds, sow them indoors 8-10 weeks before the last frost date. Fill a seed tray with seed compost and lightly press the seeds into the soil. Keep the soil moist and place the tray in a warm area until germination occurs.

If you prefer to start with cuttings or nursery-bought plants, choose healthy stems with several leaves attached. Dip the cut end of the stem into rooting hormone powder to promote root growth, then insert it into a pot filled with moist potting soil. Place the pot in a well-lit area but away from direct sunlight.

When planting periwinkle in your garden or containers, space them about 6-12 inches apart to allow for proper growth and spread. Gently loosen the roots before placing them in the planting hole and backfill with soil. Water thoroughly after planting to settle the soil and ensure good root establishment.

Watering and Care

Periwinkle plants are relatively drought-tolerant once established, but they still require regular watering during dry spells. Water deeply at the base of the plants, avoiding overhead watering that can promote fungal diseases. Check the soil moisture regularly by inserting your finger into the soil. If it feels dry to the touch, it’s time to water.

To conserve moisture and suppress weed growth, apply a layer of organic mulch around the base of the plants. This will also help to regulate soil temperature and prevent rapid evaporation.

Pruning and Maintenance

Periwinkle is a fast-growing plant that can become invasive if not properly maintained. Regular pruning helps to keep it in check and encourages bushier growth. Trim back any overgrown or leggy stems to promote more compact growth and encourage new shoots.

Deadheading faded flowers is also important to prevent self-seeding and promote continuous blooming. Pinch off the spent flowers just above a set of healthy leaves to encourage new buds to form.

Dealing with Pests and Diseases

Periwinkle is generally resistant to most pests and diseases, making it an ideal choice for low-maintenance gardening. However, like any plant, it can occasionally face some issues. Keep an eye out for common pests such as aphids or slugs, and take appropriate measures to control them, if necessary.

In terms of diseases, periwinkle can be susceptible to root rot if grown in poorly drained soil or overwatered. To prevent this, ensure proper drainage and avoid over-irrigation.

Winter Protection

Periwinkle is considered a hardy plant that can withstand cold temperatures, but extreme winter conditions can still damage it. In colder regions, apply a layer of mulch around the base of the plants in late fall to insulate them from freezing temperatures. This will help protect the roots and ensure their survival during winter.
