Scaevola is a genus of plants in the Gudenica family, native to Australia. Resistant to plant hardness zones 10-11 of the Ministry of Agriculture, Scaevols thrive in hot, sunny climates and prefer well-drained soils. Although scaevola plants can tolerate heat and drought, they can wilt due to insufficient care, disease, or invasion by sucking pests.
Excessive watering
While other plants can wilt in hot and dry conditions, lack of water is usually not the cause of wilting unless the soil is very dry. Most likely, the problem is excessive watering or the fact that the soil is constantly wet. Water the skaevola only when the soil is dry to the touch, and ensure sufficient air circulation around the plant to allow the soil and foliage to dry out.
Phosphorus
Scaevola is native to Australia, and like other Australian plants, they are sensitive to phosphorus because they have adapted to soils that do not contain large amounts of this element. Excess phosphorus in the soil can lead to discoloration and wilting of foliage. When fertilizing scaevola, use a balanced fertilizer with a low phosphorus content and a high nitrogen content. Never use bone meal as a soil additive for scavola plants, as it is a source of phosphorus.
Fungal infections
Scaevola plants are susceptible to Botrytis and Pythium diseases, especially if the soil is poorly drained. Wet roots contribute to the development of putrefactive fungi that can cause the plant to wilt. Symptoms of wilting also appear underground in the roots. Botrytis and Pythium diseases are best dealt with using proper cultural methods. Avoid watering from above and provide the plant with a space of 90 to 150 cm around it to ensure good air circulation and dry the soil and leaves. Clean the soil of dead plant material and remove dead stems and leaves from the plant. Fungicides containing mefenoxam can provide preventive control of Pythium infection. In the case of infected plants, foliar spraying with fungicides containing phocetil-al can provide control.
Sucking pests
If your scaevola plant is wilting, inspect the foliage and flowers for aphids and spider mites. Aphids are usually found on young shoots and leaves, although some species can be found on flowers. Although aphids rarely kill a plant, they can excrete large amounts of sap, which leads to decreased viability and slower growth. Aphids usually do not exceed 0.3 cm in length and are soft-bodied pear-shaped insects, whose color varies from green to yellow, black, gray or red.
Mites can also suck large amounts of sap from scaevola plants, but they are arachnids, not insects. Mites are difficult to see without magnification, but they cause spots on the leaves, which subsequently lead to yellowing and wilting of the foliage. You can also find leaves and branches covered with fine cobwebs. In most cases, strong spraying of water can remove aphids and mites from your scaevola plant. The water will also remove the honeydew left by the pests, which promotes the growth of sooty mold and attracts ants. In case of severe infection, the severely affected parts should be cut off and the soil cleared of plant debris. To combat a strong invasion of ticks, you can use oil spraying during the dormant period or repeated application of garden oil or insecticidal soap with an interval of seven to ten days.
