🌱 How to Care for Jojoba to Prevent Scale Insects?

💧 How to Water

Allow the soil to dry out completely between waterings. Once established, the plant typically only needs monthly watering to supplement natural rainfall; excess water causes yellowing and softening of the stems, a sign of root rot, while brittle leaves indicate a lack of water.

☀️ Lighting

Jojoba requires at least 6 to 8 hours of direct sunlight per day and will not grow in the shade; a lack of light leads to leggy growth and reduced flowering.

🪴 Ideal Soil

Prefer sandy or rocky, light, and very well-drained soil; the plant tolerates a wide pH range (from 5.5 to 8, or even more alkaline) as well as saline and nutrient-poor soils, but it cannot handle compact soils that retain moisture.
