Why does your Senecio macroglossus have sudden leaf drop? Diagnose the cause and fix it with our step-by-step guide.
As a tropical species, Senecio macroglossus is highly sensitive to sudden changes in environment. A rapid drop in temperature or moving the plant from shade to direct harsh sunlight can trigger an immediate defense mechanism resulting in leaf abscission.
Excessive moisture causes the roots of this succulent-like vine to suffocate from lack of oxygen, leading to root rot. As the root system fails to transport water, the plant sheds leaves rapidly to reduce transpiration.
While they prefer some moisture, letting the soil dry out completely for too long causes the fleshy leaves of the Sweetheart Vine to lose turgor pressure. The plant drops leaves to conserve internal water reserves during drought.
Small sap-sucking insects can drain the vitality of the vine's stems, causing systemic stress. Severe infestations interrupt the flow of nutrients, leading to sudden foliage loss.
