ðą How to Care for King Protea to Prevent Grey Mould?
ð§ 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.
âïļ 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.
ðŠī 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.
