Tree tags can be customized in different lengths based on the diameter of the trees.

The formula for calculating the tree circumference: Tree diameter * 3.14 equals tree circumference + 10 cm for the lock equals the total length of the tree lock required.

Trees with a diameter of 10 cm can use a 40 cm long plastic tree tag.

Trees with a diameter of 12 cm can use a 50 cm long plastic tree tag.

Trees with a diameter of 15 cm can use a 60 cm long plastic tree tag.

Trees with a diameter of 19 cm can use a 70 cm long plastic tree tag.

These four plastic lengths are fixed: 40 cm long, 50 cm long, 60 cm long, and 70 cm long. For thicker trees, only steel wire tag locks can be used. The length of steel wire locks can be custom-made and extended to different lengths.

Common features of plastic and steel wire tags:

Both can be imprinted with the nursery company name, QR code of the seedling, contact information, number segments, tree species, etc., and can be customized with different fonts.
