Over fertilising Grapevines - Q&A



Vineyard question.


Why do some vineyards re-grow after harvest? Is this a bad thing? Some growers say it is, other don't. I could of course look it up but who needs to be resourceful when you have DJ's?!


Thanks in advance.

We look out for signs of tip regrowth and pale looking fresh leaves after applying post-harvest fertiliser (below).

Unfortunately, in stressed vines such as the ones pictured the growers fertiliser has pushed new growth. This growth weakens the vine for next year, energy (carbohydrate) for next year is used up pushing this weak growth.

We don't think it is a good thing and is a sign of unbalanced vines.
