Calquat tree seed

A Calquat seed can only be planted in the Calquat patch in the Tai Bwo Wannai Village. When fully grown, calquats may be harvested.

Once grown you can harvest max of 6 Calquat at a time. Revisit after 2 hours for next harvest.

It appears that the tree can't be cut down. Use axe with tree has no effect and right-click does not offer the usual 'cut down' option. It can however be dug up by using a spade on it to clear the patch for new crops.
