Amalie Robert Estate Ask a Farmer: Trellis Design and Implementation
Hello and Welcome,
With all of the recent Supermoon and eclipse activity, we occasionally look up to the stars and wonder if there is intelligent life beyond our world. And if there is, do they look back at our world and wonder if there is intelligent life here?
The most recent federal government position seems to be “We can neither confirm or deny…” The report was written by a task force set up by the US Department of Defense. You can read all about it from the BBC. Ernie sees Unidentified Farming Objects all the time. If it looks like a dirt clod, but hops away, most likely a bunny. If it flies away, most likely a quail. No big deal.Click to view the statement from Dr. Anrak

Situational Review The recent rains in the Willamette Valley helped bring cool temperatures to slow down the vines’ rate of growth. The vines respond to the growing conditions, but in the end they will not be denied. Excess soil moisture in June, followed by seasonal heat is going to supercharge the vines’ growth. And it is our job to catch that growth in our 3 sets of handy dandy trellis catch wires. And then we gain the upper hand by hedging off the excess growth.
June growth in Pinot Noir, already above the line post!
The longest day of the year, meaning the day with the most sunlight hours was June 20th. From here on the daylight hours decrease until we reach the winter solstice on December 21st. The vines will be asleep by then, but they will start to notice the reduction in daylight hours RFN (right farming now).
Summer is officially here and we expect very little if any rain and low humidity through the month of August. It’s a nice time to visit wine country. Farming is taking center stage and it’s time for the annual parade of farm equipment maintenance. Change my oil, tighten my belt, grease my zerk, change my filters – the usual clown show. And a specialized form of farm equipment maintenance is called percussive maintenance.
You better cut it out, or I’ll pound you!
Percussive maintenance is employed when a piece of FARM EQUIPMENT is performing below its specified service level and recommended adjustments, or approved repairs have not corrected the deficiency. This form of maintenance borrows heavily from the unofficial office motivational handbook. To wit: The beatings will continue until performance improves or the equipment in question is no longer serviceable. Having arrived at this juncture, it is time to go shopping for NEW FARM EQUIPMENT.
Ask a Farmer: Trellis Design and Implementation - DEEP DIVE!
It seems we created some confusion during our last communique regarding trellis catch wires. This highlights the fact we don’t get off the farm enough in the summer. We are working the vines every day, and sometimes lose sight of the fact that not everyone is as deeply versed in the ways of viticulture as we are. We will try and be less careless.

The question centered around the catch wires and specifically how we designed the trellis to function. Note that while we designed the trellis system to be efficient, functional and easy to use, it is the field labor crew that actually implements the strategy. And here it is worth pointing out that a good strategy well executed, is better than a great strategy that no one can understand, nor implement. That is what you learn in Farming 101. And just a little bit about percussive maintenance. The trellis catch wires are a permanent fixture in the vineyard. We run the catch wires after we plant the vines and pound the end posts and line posts. The catch wires are permanently attached to each end post.

What we do is move the catch wires vertically up and down the line posts (spaced every 20 feet in the row) to catch the vines’ growth. Hence the term catch wires.

Winter pruning starts in November after harvest. At that point in the growing season, the catch wires are in their up position. After pruning, the canes are pulled out of the catch wires and laid in the grass rows for mowing. This clears the trellis so we can reposition the catch wires to catch the next year’s growth.

We run 3 sets of catch wires. After pruning, the two upper sets of catch wires are clipped into the upper most position. The lowest catch wire set is on the ground. As the vines wake up and the shoots begin to grow, we lift the first set of catch wires off the ground and clip them into the line posts capturing about 12 to 15 inches worth of growth. During this pass, we also lower the second set of catch wires to the ground. The idea is to raise the catch wires from below and catch the shoots. Please note, the galvanized steel line posts we use are only 2 inches wide. They are pre-notched with catch wire positions spaced 4 inches apart.

While it would be ideal if every shoot grew into this 2 inch opening, they simply refuse to comply. So, we lower the catch wires before the shoots are tall enough to reach the catch wire position on the line post. Otherwise, the shoots grow into the catch wires and get all tangled up and attached with their tendrils. That is a time-consuming mess to untangle, so we try to avoid it.

Then when the shoots are about 3 feet long, we come along and raise the second set of catch wires and clip them into the line post. At the same time, we lower the top catch wire to the ground. Once the vines reach beyond the top of the line posts at 5 feet, we come back and raise the third set of catch wires and clip them into position. Catching the vines growth at the right time makes all the difference. If they are too short, you miss the shoots and the tractor tires take them off – and their goes your wine berries. If they are too tall, they are unwieldy and difficult to tuck into the wires. This is the essence of a Vertical Shoot Positioned trellis system. At about a minute per vine, per set of catch wires, it is also quite labor intensive. But, if you want to grow the best wine on this planet, you have to do your part.

We are not too sure what the other galaxies are doing, but for now we are the only planet that grows wine. But things being what they are, maybe that will all change and we will start to see intergalactic trade in the Adult Recreational Beverage biosphere. We have often wondered what Romulan ale tastes like. Probably best to avoid the Ferengi wine. Most likely counterfeit anyway.
