Security

Every single Resista® elm is unique: Before sale to the nursery at the age of 4 to 5 years the breeder has inserted an electronic chip into the stem. After opner vegetation period aou cannot see the transponder any more. But you can read it with an electronic reader for at least 20 years. Therefore any Resista® elm can be identified at any stage.

The system had been developed by AEG in Ulm/Germany. Since 2003 every Resita® elm has received a chip.
