Ordering prebasic material (top-graft cuttings from the nuclear stock)
Top-graft cuttings are only supplied once a year, in winter, on principle. Deliveries in summer are feasible but not the norm. Orders are handled on a first-come, first-served basis.
Prebasic material (top-graft cuttings from the nuclear stock) is delivered primarily to P1 and P2 cutting gardens. Tree nurseries are supplied as the next priority. If too little prebasic material is available, we reserve the right to supply less material than was actually ordered.
Prebasic material is parent material for the production of certified fruit trees. The top-graft cuttings bear the official Concerplant certification label.
