🌱 How to Care for King Protea to Prevent Mealybugs?

💧 How to Water

Water deeply (soaking the root zone) only once the top few inches of soil have dried out, roughly every 7-14 days depending on climate. Reduce frequency further in cool or humid weather - soggy, waterlogged soil is the single biggest threat to this plant, quickly leading to root rot.

☀️ Lighting

Needs full, direct sun for at least 6-8 hours a day to bloom well and keep growth compact. Insufficient light produces leggy growth and few, if any, flowers.

🪴 Ideal Soil

Plant in sandy, nutrient-poor, sharply-draining, acidic soil (pH 5.0-6.5). Avoid rich garden soil, compost-heavy mixes, or fertilizers high in phosphorus and nitrogen - proteas evolved in poor fynbos soils and are easily damaged by excess nutrients.
