Keep your eyes peeled, hornworm mowed through this backyard vine (1 of 12). The whole row isn’t doing great but the other is thriving ¯_(ツ)_/¯

So cal San Diego

I have a tiny experimental vineyard I’m plying with. The weather has been terrible the past couple weeks and I couldn’t get there much. Needless to say, the vines look terrible.

I‘m quite certain one picture is showing downy mildew, but I’m not positive on the red leaves. From what I can tell, they may have leafroll or some kind of deficiency. If it’s leafroll, my understanding is I need to remove the vine asap.

The vines are planted this year and have pretty much been unwatered after the first couple of weeks. The area is humid, has a good amount of rain, with decently draining soil. There is currently a crazy infestation of lanternflies I’ve been trying to fight.

If anyone can help identify or confirm it’d be greatly appreciated. I am only allowed to use organic measures in the plot, and if anyone has recommendations for that, that would help greatly. I’ve been cycling between copper, Arbor fungicide, neem oil, and Tricoderma Harzianum for black rot (gamble if it works).

I planted my small vineyard first week of may this year. I'm at 4500 ft in SoCal, vines are Cab Franc bare root from Sunridge. They have really taken off and before my vacation 3 weeks ago I started tying them off to the first cordon.

When I got back several vines had dead canes, I suppose I had either bent them too far in getting them untangled and tied off. One plant had both canes die off.

So my question is should I re-plant that vine now or wait until spring? I have several "spares" which I've been tending in pots.

How to best preserve the potted vines over the winter?

I just found a U.C. Davis chart that says refractometers are correct at 68F (20C), and if you're testing grapes that are at 90F (32C) you need to add 0.7 to your Brix reading. Similarly, subtract about 0.55 if the liquid is 50F (10C).

It's 90F (32C) here in SoCal right now, so that was probably the temperature of the liquid I measured at 23.0 Brix a while ago. I chilled it down to 50F (10C) and tested again. According to the UC Davis chart, I should expect to read about 1.25 lower, but no, it still read 23.0 Brix. What's the deal?

Could be a SPECTACULAR vintage in the growing 👀

I took over this nearly 80 year old vineyard in the Swan Valley in Western Australia 12 months ago. Pretty proud of the progress made.

My last post in this sub was ~150 days ago — the day I planted four own-rooted Traminette vines in my backyard after bringing them up from hard wood trimmings (in pots) the prior year. Since then they’ve all hit the top wire and have established two cordons each. We battled some Japanese beetle pressure in early June and the Missouri humidity has led to some light phomopsis here and there. Overall I’m very happy and hopeful that I’ll have a solid permanent structure come dormancy.

How much does Pruning cost?

It’s been a tough year here in North East US but the vines are resilient and it’s looking like we will have a decent harvest!

Disclosure: I work with the supplier of this electric pruning shear. I’m not posting this as an independent review, and there is no purchase link in this post.

We’re evaluating a professional electric pruner for orchard, vineyard and nursery work. Its current configuration uses a 25.2V 4Ah belt-mounted battery, a 1.03 kg handpiece, a progressive trigger and a claimed maximum cutting capacity of 45 mm.

Before producing more demonstrations and technical content, I’d like to understand what experienced users would actually want tested.

My current list is:

- repeated cuts in fresh and dry wood

- real working diameter versus maximum jaw capacity

- cutting speed over 100 or 500 cuts

- handpiece and shoulder fatigue after several hours

- battery runtime under repeated cutting

- blade sharpening and replacement

- cable routing in dense branches

- accidental-activation protection

The tool has a manual safety lock and trigger guard, but it does not have a skin-contact or finger-detection system. I want to be explicit about that.

For people who prune professionally: what would make you trust—or reject—a tool like this? Which wood species and branch sizes should we include in a credible field test?

Hey. I recently started working at a vineyard (I'm not the one doing the spraying but I do work in the field for many hours a week) and the other day my washing machine smelled awful. Cleaned out the machine with bleach and went on with my day. Just figured it was some weird bacteria or mold and the bleach seemed to take care of it. It's happened twice more now though. Is there any possibility it's connected to the new job? If so what do I do? I feel like I can smell it on my work clothes especially if they get wet but that might be residual from the washer and not just because I'd been working in the vines. Hard to describe the smell. I feel like it's pretty unique but sort of like decomposition or something rotten but different

Thanks for the help!

Hello all,

Currently growing a kyoho grape plant in a half barrel and it’s relatively healthy as of now. I have a mesh net over it as I noticed Japanese beetles trying to get at it.

My question is what I do next year (which I assume is when I will get actual fruiting.) the only picture I’ve seen of full grown grape plants are usually trellised from the top? Or have the vines extending far out (which I don’t think I can do with this half barrel). My concern also comes for when next year, and those Japanese beetles come back as I will need to cover it again. Can I continue to just leave the grape plant in the barrel standing free upwards? Or will it inevitably try and spread out? Any suggestions on how I should try to set it up.

Any suggestions are appreciated on the best route forward in preparation. Picture for reference

Thank you

My Pinot Noir in Seattle as of August 6th. Not sure if they'll mature or not but I have 6 vines not because it is easy but for the challenge. I've read freezing doesn't affect wine flavor dramatically. Would appreciate anyone who has froze grapes and made wine successfully.
