Considerations for crop thinning

We talked about crop load management at the recent mid-season vineyard workshop at Wolf Mountain Vineyards and Winery.  Whether you were there or not, I hope this will serve as good food for thought if you are considering crop thinning. Depending on variety, site, and local weather patterns, some will be starting veraison…

Vineyard management – brief update

At this stage, most are hopefully finished with shoot thinning and tucking and now are doing some remedial canopy work – such as fruit-zone leafing and canopy hedging. Remember – intensive leaf removal is best done early (i.e. peppercorn to pea size berries at latest) in order to acclimate fruit…

Canopy management in the post-fruit set period

In addition to pest management (as recently posted by Nathan), canopy management is an important consideration in the early post-fruit set period. While chemical management is of utmost importance in the humid eastern US, where fungal diseases are pervasive, canopy management is a good supplement as it aids in canopy and fruit-zone drying, spray…

Petiole sampling at bloom

Since the first seasonal opportunity for vine tissue sampling comes at bloom, this message may be timely for vineyards that are northerly and/or at higher altitudes, but somewhat late for those located more southerly and/or at lower altitudes. Bloom-time petiole sampling is a good tool for those interested in learning…

Update: early-late bloom / fruit set

The last post I wrote on May 17 was optimistic for a good fruit set given the wonderful weather we were experiencing last week. Key word here is “were”. The weather has been rather wet, cool, and rainy from this past weekend, and continuing through tomorrow.  This has been particularly true throughout northern GA, but I’ve also…

Fruit set – what it is, and what can affect it

Now that we are getting close to fruit set (and maybe even seeing a bit in early varieties planted in southern / lower altitude vineyards), it is a good time to review fruit set, what can impact it, and what this means in an applied sense. Flowering (see left picture, below)…
