PLANTING and AFTERCARE GUIDE

Sunlight: Choose a position in partial shade with shelter from strong winds. Blechnum thrives in sheltered, humid conditions with filtered light.
Soil: Moist, well-drained soil rich in organic matter is ideal. Incorporate compost or leaf mould to improve moisture retention and soil structure.
Planting Instructions
Prepare the Hole: Dig a hole twice the width of the root ball and the same depth so roots have space to spread.
Soil Preparation: Mix compost or organic matter into the excavated soil to enrich it and retain moisture.
Planting: Position the plant so the root ball sits level with the surrounding soil, then backfill and firm gently.
Watering After Planting: Water thoroughly after planting to settle the soil and help Blechnum brasiliense ‘Volcano’ establish quickly.
