Early cane hardening - Lignification

Over the last 10 days many vineyards have shown signs of shoot lignification (also called browning or hardening off).

A rough rule of thumb is for balanced Shiraz and Cabernet you should see 50% shoot lignification at veraison. This season most vines are showing lignification before veraison as a result of a dry spring and some water stress due to low soil moisture.
