Growing Guide: Lily Thorn
Growing Tips
(Also known as: Lily Thorn, Spanish Guava, Prickly Apple, Huevo de Aura, Huevo Vegetal*)*
Plant in full sun to light shade with rich, well-draining soil. Keep evenly moist while establishing, then allow the soil to dry slightly between waterings once mature. Protect from frost and prolonged cold; Lily Thorn thrives in warm, humid conditions and is best suited to Zones 10–11.
Fertilize during the growing season with a balanced tropical or fruit fertilizer. Prune lightly to shape and encourage branching, taking care around its sharp thorns. Grow in the ground in warm climates or in a container where it can be protected from cold. Expect slower growth in cool or dry conditions, with yellow fruit developing after flowering once the plant is mature.
