047: Crop Regulation & Fruit Thinning Strategies with Dr. Mark Krasnow

Vineyard Underground

Join us in this episode with Dr. Mark Krasnow, an acclaimed plant physiologist and the founder of Thoughtful Viticulture. From the landscapes of New Zealand, Dr. Krasnow takes us on a journey from budding winemaker to viticulture expert. Although we could discuss many topics with him, this discussion focuses on crop regulation and fruit thinning strategies.

Many vineyard management techniques are universal, while others are location-specific. Listen in to learn some new strategies and begin implementing them in your vineyard.

In this episode, you will hear:

• Reasons growers choose to reduce crop in their vineyard or aim for a specific crop load on their vines.

• When to thin and start cropping young vines, including a strategy for guidelines.

• Differences in crop regulation needs when cane pruned versus spur pruned.

• What research tells us about fruit removal from shoots during the growing season.

• Pros and cons of early versus late fruit removal.
