Cutting up of 'foundation block' rootstock

20 May 2009 Mischa Vines received its first batch of rootstock from its foundation block, namely US 8-7. We receive the rootstock in bundle form and then cut the rootstock up according to the standards set out by the Vine Improvement Association (VIA). For optimum quality it's important that the shoots are mature over the entire length and are free of damage. The physical requirements for certified shoots are a minimum internode diameter of 6,5mm, but no less than 70% of graft shoots are not allowed to be less than 7mm in diameter. The maximum internode diameter is 12mm.
