🌱 How to Care for Adam's Needle to Prevent Scale Insects?

💧 How to Water

Water deeply but infrequently — every 2–3 weeks in summer, once a month or less in winter. Always let the soil dry out completely between waterings. Overwatering is the number one killer; Yucca filamentosa is highly drought-tolerant.

☀️ Lighting

Requires full sun for at least 6 hours a day. In partial shade it will grow but flower less and develop a less compact form. Place it in the sunniest spot in your garden, away from shade from buildings or trees.

🪴 Ideal Soil

Plant in any well-draining soil — sandy, loamy, or even rocky. Avoid clay-heavy or waterlogged soils. Drainage is essential to prevent root rot. Does not need rich or fertile soil; lean soils are perfectly fine.
