All,
My bines growing in half wine barrels in general are doing great. But in the last three weeks, the tops of the centennial bines are turning purple. Like when you put celery in water with purple food color in the water. All other signs are that they are doing great. The leaves are deep green and look heathy. The rest of the bine looks great.
Could this be a sign of a micronutrient deficiency?
Thanks,
The Fool
