How to Transplant Periwinkle

Periwinkle, or vinca, grows over garden beds and provides an attractive, flowering groundcover. Each plant spreads over an area of two feet or more, quickly covering bare soil and providing a lush carpet of foliage. Periwinkle remains evergreen up to USDA hardiness zone 4, growing well in most areas of the United States. Transplanting it to the garden from nursery grown plants provides you with established young plants that are able to quickly root and begin spreading in your groundcover beds.

Soil test kit
Lime or sulfur
Trowel

Instructions

- 1
  Test the soil in a well-drained, full-sun bed with a soil test kit to determine the pH of the site. Adjust the pH with lime or sulfur, as recommended by the test, so the pH is between 6 and 6.5 before planting. Lime will make the soil more alkaline, while sulfur makes it more acid.
- 2
  Dig the planting hole with a trowel, making it the same depth as the periwinkle pot. Space the planting holes 8 to 12 inches apart so the plants don't crowd each other at maturity.
- 3
  Remove the pots from the root ball of the periwinkle plants. Set the periwinkles in the planting holes and adjust the hole depth so the plant sits in the bed at the same depth it was in the pot.
- 4
  Fill in around the plant's roots with soil. Firm it in place with your hands.
- 5
  Water the newly transplanted periwinkles at their base and avoid wetting the foliage. Add more soil to the planting holes if it settles after watering.
