Grape Bud Analysis

 

              We Do This                                                So You  Can

Count bunches per bud.                          Adjust pruning decisions.
                                                                   Reduce thinning costs.
                                                                   Leave extra spurs or canes.

Diagnose fruitfulness problems.           Consider carbohydrates.                                                        Consider nutrition.
                                                                  Be aware of pathogens or stress.
                                                                  Assess frost damage.
                                                                  Control bud mites.

Estimate relative bunch size.                 Compare size year to year.                  

 

In grape bud analysis, our inspectors dissect buds under a microscope to count the tiny bunch primordia that will become next year's crop.  If you choose, we will also estimate the relative size of the primordia.

When we find high fruitfulness, our growers can safely minimize the number of spurs or canes they leave on the vines after pruning.  This reduces thinning costs in the spring.

When we find unusually low fruitfulness, our growers are forewarned to modify their pruning to add more bunches by leaving more or longer spurs and canes.

When vineyards suffer from low production, our analysis of unfruitful buds provides clues about the causes, which may stem from failed inflorescence, bud necrosis, some kind of stress, bud mites, or disease.

In vineyards infested with bud mites, we count the percent of buds infested and the level of damage to the bunch primordia.
