Why Choose 25mm Rundle Rock for Landscaping?
Rundle Rock is valued for its dark charcoal colour and naturally fractured appearance. The angular stones create texture and contrast, especially when paired with green lawns, ornamental grasses, shrubs and lighter paving stones.
The 25mm size works well as decorative ground cover without the oversized appearance of larger landscape rock. Its angular shape helps the stone settle together within properly edged garden beds and landscape borders.
For low-maintenance garden beds, suitable landscape fabric can help separate the rock from the soil and reduce weed growth. Rundle Rock is intended primarily for decorative applications rather than engineered compacted bases.
