As the seasons turn, I’m starting to think about when to take the grow tubes off my vines. For those who may not want to scroll back up, I’m in the Paso Robles area of Central California. Temperatures are going to be in high 80s low 90s for highs, mid to high 50s for overnight lows for the next week.
All of the grapes have grown above the 24 inch tubes, all of the ones that weren’t trimmed by the deer have reached or surpassed the 40 inch (give or take) cordon wire. The vines are still growing - no signs of leaves turning color or anything. I have ten tracking vines, two of each Varietal, and they grew an average of 1.25 inches this last week (I measure on Sundays). Average height is 6 feet 3 inches (Measuring the biggest cane which is not always the longest).
So I am getting, as per usual, conflicting advice from the local growers. So I thought I’d throw it out here.
1) should I start removing the tubes now? Or should I waiting until things cool off more and growth stops? Or should I wait for Winter pruning and do it then?
2) when I pull the tubes, assuming things are still green and growing, should I clean up the suckers, spindly branches etc. or wait until the pruning season in January.
Appreciate the advice
