| You can plant perennial groundcovers in the fall months. In fact, it's easier for new plants to adjust to their new surroundings when the weather is cooler and they get natural rainfall. Don't expect much top growth until spring, even though the roots will continue to grow during the cool weather. Be sure to prepare the planting area well before installing your new groundcover. Spread several inches of organic matter, such as compost or aged manure, over the top of the soil and dig it in to a depth of about six inches. Then plant your periwinkle and water each plant well. By spring time the roots will be established and the plants will spread and flower for you. |
