FAQ - 💬
❓ Why is my vinca plant dying?
👉 Even though its native environment is along river beds, Vinca is still a plant that can die due to too much water. Whenever drainage is poor, water sits and roots can't breathe. Fungus start developing, and ultimately they spread to the whole plant which dies.
❓ What is killing my vincas?
👉 But in recent years, this bedding plant's luster has faded as it has increasingly been subject to a type of fungal blight that shrivels its leaves and can eventually kill off every vinca in a bed. Blame it on a type of phytophthora, a fungus that lives in the soil.
❓ Why do my vinca flowers have white spots?
👉 The fungi Alternaria alternata and Ulocladium species occasionally cause spots on foliage, stems, and petioles. Symptoms first appear on lower leaves and stems, and if left unchecked, move upward. Spots caused by both fungi are small, ranging from the size of a pinhead to 1/8 inch in diameter.
❓ What is eating my vinca flowers and leaves?
👉 Some of the more commonly seen pests on annual vinca plants include aphids, spider mites, scale, and whiteflies. Generally, most of these pests can be controlled with beneficial insects that feed on them or with the use of insecticidal soap or neem oil.
