Phosphorus sensitive natives

Australian native plants are phosphorus sensitive. Most fertilizers contain phosphorus so it is important to purchase a fertilizer that doesn’t contain phosphorus. Australian soils are deficient in Phosphorus so plants have evolved so they don’t need it or take it up. The problem is that phosphorus binds to iron, therefore because the plant won’t take up the phosphorus it misses out on the iron, therefore the plant becomes deficient in iron which will eventually lead to its death.
