Periwinkle is a popular ground cover that can add a beautiful touch to any garden or landscape. With its lush green foliage and delicate flowers, it’s no wonder why so many people choose to plant periwinkle in their yards.
But when it comes to planting this ground cover, many people are left wondering how far apart they should space the plants. In this article, we’ll explore the different factors to consider when planting periwinkle and provide you with some helpful tips on how to space your plants for optimal growth and coverage.
So, whether you’re a seasoned gardener or just starting out, read on to learn more about how to plant periwinkle ground cover.
How Far Apart To Plant Periwinkle Ground Cover
When it comes to spacing periwinkle ground cover, there are a few things to consider. First, it’s important to determine the size of the area you want to cover. This will help you determine how many plants you need and how far apart to space them.
In general, periwinkle should be spaced between 12 and 18 inches apart. This allows enough room for the plants to grow and spread, while still providing adequate coverage. However, if you want faster coverage, you can space the plants closer together at 6 inches apart. Keep in mind that this will require more pruning in the future to prevent overcrowding.
Another factor to consider is the amount of sunlight the area receives. Periwinkle prefers partial shade but can also grow well in full sun. If planting in full sun, it’s recommended to space the plants a bit further apart to prevent them from drying out or becoming too crowded.
It’s also important to ensure that the soil is well-drained and moist. Periwinkle prefers soil that is rich in organic matter, so adding compost or peat moss before planting can help improve soil quality and drainage.
When planting periwinkle, be sure to water the soil deeply after planting and keep it evenly moist during the first 6-10 weeks while the roots become established. Fertilize with a complete fertilizer such as 10-10-10 in the spring at a rate of 6-8 pounds per 1,000 square feet.
Understanding Periwinkle Ground Cover
Periwinkle ground cover is a popular choice for gardeners looking to add an evergreen, low-maintenance plant to their landscape. Periwinkle, also known as Vinca minor or Vinca major, is a herbaceous perennial that produces dainty blue-lavender flowers against a backdrop of dark green foliage in spring and early summer, with intermittent blooms throughout the year.
Periwinkle is an excellent ground cover that can prevent weed growth and cover awkward spots in your garden. It grows quickly and aggressively, sending out long trailing and rooting shoots that can make new plants. However, it’s important to note that periwinkle can also become invasive if not kept in check.

Ideal Spacing For Periwinkle Plants
The ideal spacing for periwinkle plants depends on the size of the area you want to cover and how quickly you want the plants to fill in. For smaller areas, it’s recommended to space the plants 8 inches apart for quick coverage. For larger areas, space them between 12 and 18 inches apart to allow room for growth and prevent overcrowding.
If you want faster coverage, you can space the plants closer together at 6 inches apart. However, keep in mind that this may require more pruning in the future to prevent overcrowding.
It’s also important to consider the amount of sunlight the area receives. Periwinkle can tolerate both partial shade and full sun, but if planting in full sun, it’s recommended to space the plants a bit further apart to prevent them from drying out or becoming too crowded.
In addition to spacing, it’s important to ensure that the soil is well-drained and moist. Adding compost or peat moss before planting can help improve soil quality and drainage.
Tips For Planting Periwinkle Ground Cover
Here are some additional tips to keep in mind when planting periwinkle ground cover:
1. Use divisions or nursery transplants: Periwinkle can be grown from seed, but it grows slowly. It’s better to use divisions or nursery transplants for quicker results. Just a few plants will spread to fill in a large area.
2. Enrich the soil: Before planting, enrich the soil with compost, manure, and peat moss to improve drainage and provide more nutrients for the plants.
3. Plant in either sun or shade: Periwinkle can grow in either sun or shade, but it’s important to protect it from wind and water it when the temperature is above freezing in cold, harsh climates to prevent winter burn.
4. Space plants properly: Space periwinkle plants at least 12 to 18 inches apart to allow enough room for growth and prevent overcrowding.
5. Plant in spring or early fall: The best time to plant periwinkle is in spring or early fall when the weather is mild and the soil is moist.
6. Water deeply after planting: Water the soil deeply after planting and keep it evenly moist during the first 6-10 weeks while the roots become established.
7. Fertilize in spring: Fertilize periwinkle in spring with a complete fertilizer such as 10-10-10 at a rate of 6-8 pounds per 1,000 square feet.
8. Mulch dry soils: Mulch dry soils to conserve moisture and provide more nutrients for the plants.
9. Contain the spread of periwinkle: Dig out and throw away any plants growing out of bounds to contain periwinkle, especially if your soil is moist and rich.
By following these tips, you can successfully plant periwinkle ground cover and enjoy its beautiful blooms and foliage for years to come.
Maintenance And Care For Periwinkle Plants
Once your periwinkle ground cover is established, it’s important to maintain and care for it properly to ensure its continued growth and health. Here are some tips for maintaining and caring for periwinkle plants:
Weeding and mulching: Weeding and mulching are required on a regular basis until the groundcover fills in the planted area. This will help prevent weeds from overtaking the periwinkle and keep the soil moist.
Pruning: Occasionally shear plants close to the ground to encourage new growth. You can even mow periwinkle in spring if it begins to look straggly. Set the mower blade to its highest setting. Pruning will help keep the plants from becoming too dense and overcrowded.
Watering: Periwinkle prefers moist, well-drained soil, so be sure to water it regularly, especially during hot, dry weather. However, be careful not to overwater, as this can lead to root rot.
Fertilizing: Fertilize only when necessary, preferably in the spring with a complete fertilizer such as 10-10-10 at a rate of 6 to 8 pounds per 1,000 square feet. Too much fertilizer can cause excessive growth and make the plants more susceptible to disease.
Propagation: Propagate by taking tip cuttings of non-flowering stems in late spring or divide throughout the season. This will help you expand your periwinkle ground cover and keep it looking healthy and full.
By following these maintenance and care tips, you can ensure that your periwinkle ground cover remains healthy and vibrant for years to come.
Troubleshooting Common Periwinkle Issues
While periwinkle is a hardy plant, it can still be susceptible to various issues. Here are some common problems and how to troubleshoot them:
1. Vinca Wilt: This disease is caused by Spiroplasma citri and can cause mosaic, yellowing, stunting, and wilting of periwinkle plants. It is spread by the beet leafhopper, which is known for carrying plant viruses. To prevent this disease, it’s important to control the population of leafhoppers in your garden. Remove and discard infected plants and do not replant periwinkle in the same area.
2. Rhizoctonia: This fungus disease can cause the wilting death of periwinkles by rotting the stems at ground surface. It is common in local flower beds all year round, and periwinkle is highly susceptible. To prevent this disease, ensure that the soil is well-drained and moist. Avoid overwatering and remove and discard infected plants.
3. Thielaviopsis basicola: This fungus lives in the soil and attacks the roots through a wound or nematode damage. Ideal conditions for this disease include cold, damp soils with a pH near neutral. To prevent this disease, provide excellent drainage by adding organic materials such as composted pine bark to the soil before planting. Remove and discard infected plants.
4. Scale Insects: Three types of scale insects commonly attack periwinkle, including greedy scale, oystershell scale, and black scale. Aphids are also vectors of numerous plant viruses which they can spread to susceptible plants. To prevent these insects from damaging your plants, monitor them regularly and use insecticidal soap or horticultural oil to control their populations.
5. Fungal Diseases: Phytophthora blight and leaf spot are fungal diseases that can infect periwinkle plants, especially during rainy seasons or when planted in less than ideal conditions. Infected plants first demonstrate signs of infection in the form of yellow to dark brown spots on leaves. As the disease progresses, the plant and roots may begin to rot. To prevent these diseases, ensure that the soil is well-drained and moist. Avoid overwatering and remove and discard infected plants.
By following these troubleshooting tips, you can keep your periwinkle ground cover healthy and thriving for years to come.
