I have some issues with my grape vines, other than mildews.
In addition to spraying against downy and powdery mildew, I am spraying with a leaf nutrient to try and alleviate problems with NPK and Magnesium deficiency.
Is using leaf nutrients my best option in the long term for vine health? Is there a better solution? Would it be better to spread fertilizer on the ground, and thus fertilize the roots and overall vine?
I have lost about 6 vines since last year due to what appear to be cankers in the branches. Could deficiencies in my vines make them vulnerable to cankers, and possibly prevent bud break?
Edit > It has rained a lot this year, could an excess of water be causing some of my leaves to appear magnesium deficient and lighter in colour than other leaves?
