🌱 How to Care for Golden Barrel Cactus to Prevent Whiteflies?
💧 How to Water
Water deeply only when soil is completely dry. In summer, once every 15-20 days; in winter, reduce to once a month or less. Overwatering causes root rot.
☀️ Lighting
Requires full direct sunlight for at least 4-6 hours daily to maintain compact growth and vibrant golden spines. Gradually acclimate nursery plants to direct sunlight.
🪴 Ideal Soil
Use specific cactus substrate with excellent drainage: coarse sand, perlite, and minimal organic matter. Tolerates slightly acidic to alkaline soils (pH 6.0-7.5).
