DETAILS

Care Instructions
Gunnera manicata requires consistently moist soil and indirect bright light. It thrives in moderate temperatures and high humidity. Ensure the plant is protected from direct sunlight to prevent leaf burn. During its dormancy period in winter, reduce watering but do not let the soil dry out completely.
Soil
Gunnera manicata prefers loamy soil that is rich in organic matter. The soil should be well-draining yet consistently moist. Adding compost or well-rotted manure can help improve soil fertility and structure.
Fertilizer
Use a balanced fertilizer with an N-P-K ratio of 10-10-10. Fertilize the plant during the growing season, typically from spring to early autumn, every 4-6 weeks to support its vigorous growth.
Repotting
Repot Gunnera manicata every 2-3 years or when it outgrows its container. Choose a large pot with good drainage and fill it with a rich, loamy soil mix. Repot in early spring before the growing season begins.
Propagation
Gunnera manicata can be propagated by division. The best time to propagate is in early spring. Carefully divide the rhizomes, ensuring each section has at least one bud, and replant them in moist, fertile soil.
Pruning
Prune Gunnera manicata to remove dead or damaged leaves and to control its size. Pruning is best done in late autumn after the first frost. Cut back the leaves to the base, and cover the crown with mulch to protect it during winter.
Toxicity
Gunnera manicata is not known to be toxic to pets or humans. However, its large leaves can be sharp, so handle with care to avoid cuts.
Additional
Gunnera manicata is a striking plant that can serve as a focal point in a garden. It is ideal for planting near water features or in bog gardens where the soil remains consistently moist. Protect the plant from strong winds, which can damage its large leaves.
