The warm climate regions of the Riverland and Sunraysia have a window of about 6 weeks between harvest and senescence. Sam Bowman’s focus during this time is on irrigation and nutrition to build carbohydrate stores in the plant. During the post-harvest period, the vines switch from moving carbohydrates into the ripening fruit to building reserves for the next season’s buds. Active management post-harvest is a crucial step in avoiding the trap of biennial bearing.
