Beurré Hardy Interstem
 
The most widely used compatibility aid when grafting a Pear variety onto a Quince Rootstock (Quince A, BA-29C or C). 
The Beurre Hardy forms functional vascular connections between the quince rootstock and the scion variety that would otherwise be incompatible.
 
Each interstem is a 200mm length, and approximately pencil thickness. 
 
Please advise if scions to be grafted are larger than this, as we can supply a larger calliper interstem upon request.
