IntroductionIntroduction

This is a look at a unique problem in a vineyard in Hawke’s This is a look at a unique problem in a vineyard in Hawke’s Bay. Approximately 500 Chardonnay vines had been inter-Bay. Approximately 500 Chardonnay vines had been inter-planted within approximately 3700 Malbec vines.planted within approximately 3700 Malbec vines.

The 2002 plantings were purchased The 2002 plantings were purchased from a now defunct nursery and from a now defunct nursery and grafter from Gisborne. The story grafter from Gisborne. The story was that there was a disgruntled was that there was a disgruntled employee at the nursery and he employee at the nursery and he ‘peppered’ the Malbec with ‘peppered’ the Malbec with Chardonnay vines.Chardonnay vines.

The discovery was not made until The discovery was not made until 2005 when the first fruit came off of 2005 when the first fruit came off of the vines. Part of this was due to the vines. Part of this was due to viticulture inexperience, but who viticulture inexperience, but who could have known such a thing could have known such a thing would happen. Without serious would happen. Without serious consideration or laboratory consideration or laboratory analyzation, even the most analyzation, even the most experienced viticulturist may not experienced viticulturist may not have discovered the issue till the 2have discovered the issue till the 2ndnd year.year.

Decision timeDecision time In the autumn of 2008 it was In the autumn of 2008 it was

decided to transplant the decided to transplant the Chardonnay vines to their Chardonnay vines to their own section of the vineyard, own section of the vineyard, once the vines went into once the vines went into dormancy.dormancy.

There are certainly positives There are certainly positives and negatives to this decision and negatives to this decision and each depend solely on and each depend solely on the type of vineyard, financial the type of vineyard, financial situation, status of disease, situation, status of disease, and resources available.and resources available.

Many times these are the Many times these are the factors driving the decisions factors driving the decisions in the vineyard. It never is in the vineyard. It never is purely a ‘best case scenario’.purely a ‘best case scenario’.

Justify the decisionJustify the decision First and foremost, it was one alternative to fixing the First and foremost, it was one alternative to fixing the

problem of having to continuously cut out and drop the problem of having to continuously cut out and drop the Chardonnay fruit before the Malbec harvest. Each season Chardonnay fruit before the Malbec harvest. Each season this proved very laborious task.this proved very laborious task.

Owners of the vineyard liked the idea of having a bit of Owners of the vineyard liked the idea of having a bit of Chardonnay to make for themselves in future years.Chardonnay to make for themselves in future years.

and root stocks were unknown. In fact, it’s not even certain and root stocks were unknown. In fact, it’s not even certain that these vines were all Chardonnay. So there was no way that these vines were all Chardonnay. So there was no way to know if these root stocks suited the soil types or if they to know if these root stocks suited the soil types or if they would work well with grafted Malbecwould work well with grafted Malbec

To find out these rootstocks would be far too laborious and To find out these rootstocks would be far too laborious and expensive. So the decision to remove and replant with expensive. So the decision to remove and replant with proper Malbec on the correct rootstocks.proper Malbec on the correct rootstocks.

Another solution to help combat this Another solution to help combat this was to plant in a more ‘water was to plant in a more ‘water retaining’ soil. This picture was retaining’ soil.

Basically we had to take each Basically we had to take each vine very specifically. That is vine very specifically. That is true for all pruning and true for all pruning and thinning but this truly proved thinning but this truly proved to show many different to show many different scenarios. Some vines we scenarios. Some vines we had to spur prune, and where had to spur prune, and where ever we could we attempted ever we could we attempted to lay down new canes and to lay down new canes and could out as much of the could out as much of the gnarled crowns and cordons gnarled crowns and cordons from the previous years from the previous years issues.issues.

Notice the vine in the Notice the vine in the background. This vine had to be background.

One technique I learned One technique I learned from working up in from working up in Northland where the Northland where the climate is much more climate is much more humid, was to not just humid, was to not just glob on the backseal, but glob on the backseal, but to put a thin layer over to put a thin layer over to protect and not get to protect and not get any moisture caught any moisture caught under the back seal.under the back seal.
