Your project is really shaping up well. I can’t remember from your old thread, are you planning to sell your eventual harvest to a winery or start one of your own? lol

Preemergent herbicides actually require a certain amount of rain, normally 1/4”-1/2”, to activate in the soil. Large rain events will cause its effectiveness to decrease sooner, but you can reapply later in season to get you through the rest of the year.

How old are your vines? There are several products you can use to keep weed seed from germinating, but with some of them you can’t get any on new growth. I used Prowl, but chateau (aka valor) would work well too. The thing about weeds is even if you kill them, more will always come with rain...

They are definitely not immune. The best you can hope for if any hits a leaf is you don’t kill them and they look ugly for a year while they metabolize the glyphosate. Use grow tubes and hill soil around the bottom if you need to use roundup. there are several brands of glufosinate that will...

Sulfur is mobile in the soil like nitrogen and much of it leaches with rainwater. Using sulfur fungicide won’t cause any”imbalance” in your soil.

I bet you’re glad to be done! It’s a lot of work, but really worth it once they start growing. My advice is to care of your vines this year and things will go better in the future. I had to replant my whole vineyard after one year (thankfully I bought the vines with credit card points). I...

I’m looking for some advice. I’ve got some Regent grapes that are going into their second growing season in Michigan (5b/6a) that did rather well last year. Some of them had enough growth to start one arm of a cordon and I’d select the other from this year’s growth. I’m just starting to see...

That’s true. It might not have been in their tank mix, but if they didn’t clean their tank really good (likely that they didn’t) from the last place the grapes probably got just enough of a whiff of 2-4D they showed injury. I had some drift over a half mile and get mine last summer.

A closer picture would help but it definitely looks like herbicide damage. A crabgrass preventer is probably a group 3 herbicide. Some of them are labeled for grapes, but if it gets on green growth it will cause damage. It is possible some has been take up by the roots as well. The grapes...

Boron, like nitrogen, is extremely mobile in the soil so annual applications may be your best bet. If you’re seeing foliar symptoms of deficiency, there are a lot of products that you can readily mix with a fungicide spray. Your best bet is to contact your local ag retailer.

HJW is a great nursery, I have a few vines from there. My in-laws know one of the owners and they are super nice people too.

I experimented last year moving some random 2 year old Riesling vines that survived a harsh winter in order to replant with some more hardy varietals. I didn’t have trunks established so I pruned them back a bit and hoped for the best. By the end of summer every one had some growth. I pruned...
