How to keep Arenga Australasica.
Pruning
Arenga australasica is known for its vigorous growth and feather-like fronds. To maintain its health and appearance, prune it in early spring. This is the best time to remove dead fronds and promote new growth. When pruning, cut close to the trunk to ensure effective results. Regular pruning not only improves the plant's size and aesthetics but also minimizes stress by targeting only the deteriorating parts.
