Rubber Trees and Resin

Rubber trees grow in forests, swamps and taiga (rarely in plains). Look for the narrow leaf spike on top and orange resin holes on the pale trunk (up to 3 per tree).

Right-click a wet hole with the Treetap: 1–3 Sticky Resin. The hole turns dry (dark) and refills on its own after a few minutes.

When you fell the tree, a wet hole sometimes still drops resin; the leaves decay and drop saplings (bone meal helps them grow).

Resin in a furnace = 1 Rubber, in an Extractor = mp;23 rubbermp;r. No tree nearby? A slimeball in a furnace also gives rubber.
