🌱 How to Care for Queen Palm to Prevent Fusarium Wilt?

💧 How to Water

Water every 7 to 14 days depending on season and climate. Allow the top 2-3 inches of soil to dry between waterings. Avoid waterlogged conditions as root rot is the most common problem. During hot summers, increase watering frequency slightly.

☀️ Lighting

Queen Palm requires full sun — at least 6 hours of direct sunlight daily. It does not tolerate low-light conditions and is not suitable as an indoor plant. In hotter climates, afternoon shade for young specimens can help establishment.

🪴 Ideal Soil

Prefers well-draining soil with a slightly acidic pH of 5.5–7.0. Sandy loam or loamy mixes with organic matter work best. Avoid alkaline soils as they cause severe micronutrient deficiencies, particularly manganese and magnesium.
