VINEYARD be planted when root systems have just filled their container volume, a point in time that would ideally coincide with optimal soil and air temperatures. Holding vines in containers past their prime causes severe damage to root system architecture (pot- bound vines, root binding), lead- ing to stress and vine decline. The planting window for best perfor- mance from potted vines is very limited – a matter of perhaps only two weeks. Initiation of potted-vine TABLE 1 Product Dormant rooting propagation must be timed to coin- cide with best time to plant – about 14 weeks later – usually in May in California. Dormant vines are best planted as soon as possible in the spring to provide for the longest grow- ing season and shortest time in cold storage (at the nursery). There is a direct correlation between extended cold storage and uneven and irregular vine development. Cold-stored vines metabolize car- bohydrate energy reserves better Place order (for planting spring 2013)* Jan. 2012- Feb. 2013* Budwood for FG-spring '13 June 2012- Oct. 2012 Budwood for FG-fall '13 Dormant BG Green potted BG Dormant potted BG BG: bench graft Sept. 2012- Sept. 2013 Sept. 2011- March 2012 July 2012- Feb. 2013* Not recommended FG: Field graft CG: crown gall *Place orders earlier for in-demand rootstocks (420A, VR 039-16, 1616C) and scion selections Ideal plant/ graft time Jan.-May 2013 May 2013 Sept. 2013 Jan.-May 2013 May 2013 Pros Delayed scion choice Fresh wood, reduced CG?

Rootstock rootings and pot- ted vines permit delayed selection of scion choice, but there may be consequences associated with this (Table 1). The success of field graft- ing may be severely affected by difficult weather conditions, while the creation of fresh wounds on the rootstock may stimulate crown gall development. Crown galls, which develop at the graft union, may ulti- mately girdle and kill the vine.
