How to keep Gunnera Magellanica.
Light
Gunnera magellanica is native to habitats like forest understories and rocky sites, where it typically occurs in natural shade. It favors partial sun but can tolerate full sun or full shade, reflecting its hardy and adaptable nature.
Temperature
Gunnera magellanica can tolerate a wide range of temperatures, though its distribution may still be restricted by particular combinations of moisture and heat. It performs best in warm summer conditions with sufficient rainfall or irrigation. Extended periods of cloudy, rainy weather or prolonged high temperatures can increase the chance of the plant dying. In winter, protecting it from cold can enhance its survival rate.
Fertilizer
Usually one fertilizer application in spring is enough for Gunnera magellanica, though repeated feedings can optimize growth. Fertilize about every month to month and a half. Feeding improves the leaves' appearance and function, maintaining even color and a healthy texture. It also promotes root development and nutrient uptake for long-term plant health.
Pruning
Gunnera magellanica is a low-growing ground cover that features large, textured leaves. To keep it healthy and vibrant, prune the plant in early spring to remove any dead foliage and improve air circulation. This promotes vigor and helps prevent disease. Regular pruning not only enhances the plant's appearance but also supports its healthy growth throughout the year.
