Proteas are well adapted to our Mediterranean climate, making them carefree plants with bountiful rewards. After a few years, when your protea is established, it will want deep watering every couple weeks, though it will tolerate more if the drainage is excellent. Protea respond very poorly to clay soils, especially if they are overwatered. If you just have to plant one in your clay garden, mounding or planting on a slope can help. Also amending with liberal minerals such as lava or pumice helps. | |

Notas de cultivo
While protea can typically be kept smaller through pruning this one rarely needs it, naturally growing into a tidy small shrub.
Proteas have evolved to live in very poor soils, and so they should never have phosphorus fertilizer, which many a grower has learned the hard way. If you give your protea all-purpose fertilizer, it'll likely be completely dead within a couple weeks. They do respond well to light acidic fertilizer, such as cotton seed meal, or nitrogen fertilizers such as blood meal and fish emulsion. Generally its better to sit back and see how the plant grows without fertilzier, which is typically not needed.
Relatively short lived, around ten years, for a protea.
Interés especial
Their coveted flowers on stiff stems are long-lasting after they're cut, perfect for arrangements.
