What is the best soil type for a Bigleaf Periwinkle?
The Bigleaf Periwinkle (Vinca major) prefers well-draining soil that is moist and rich in organic matter. It can grow in a wide range of soil types, including loam, sandy soil, and clay soil, but it does better in soils that are slightly acidic or neutral. Adequate water is essential for the proper growth of the plant, and it cannot survive in waterlogged or extremely dry soil conditions.

Bigleaf Periwinkles prefer moist soil, but they do not tolerate waterlogging well. Therefore, water the plant regularly, keeping the soil consistently moist but not waterlogged. Allow the top inch of soil to dry out slightly before watering again. In hot weather, they may require more frequent watering, so monitor the soil moisture level carefully. It is best to avoid wetting the foliage while watering, as it can make the plant more susceptible to diseases.
How should temperature and humidity be adjusted for a Bigleaf Periwinkle?
Bigleaf Periwinkles prefer temperatures between 60-75°F (15-24°C), and humidity levels of around 50-60%. Keep the soil of the plant moist, but not overly wet, and provide good air circulation to prevent any fungal growth or disease issues. A well-draining soil with plenty of organic matter is also important for healthy growth.
How should fertilization be used for a Bigleaf Periwinkle?
Bigleaf Periwinkles, also known as Vinca Major, do not require much fertilization. It is best to use a balanced fertilizer with equal amounts of nitrogen, phosphorus, and potassium. Apply the fertilizer in early spring after the last frost and before flowering. Avoid applying fertilizer during the growing season as it may cause excessive growth and reduce flowering. Always read and follow the instructions on the fertilizer label for specific application rates and methods. Over-fertilization can be harmful to the plant and the environment, so it is important to use fertilizers responsibly.
How can a Bigleaf Periwinkle be multiplied?
Bigleaf Periwinkle (Vinca major) can be multiplied through both division and stem cuttings. Division: Mature plants can be divided into smaller sections in early spring or fall. Separate the roots gently and plant each section in well-drained soil. Stem Cuttings: Take stem cuttings in early summer or fall. Cut several 4-6 inch long stems just below a leaf node. Remove the leaves from the bottom half of the cutting and dip the cut end into a rooting hormone powder. Plant the cutting in a well-draining potting mix and keep it moist until roots form. Transplant the new plant into a larger pot or into the garden.
What should be considered in the selection of a pot for a Bigleaf Periwinkle?
