Just used this... It worked great on the blackberry that was in the sun, but not on the vines in the shade. Why not?

Did you use it full strength? Sun or shade is a non-factor. The acid works by burning the foliage but does not necessarily kill the entire plant like an actual herbicide does. It will kill a very young tender plant, but probably not a hardy established one, and especially not if the plant has a moderately thick or woody stem.

The acid removes the waxy coating on the plant and then the sun is free to dry the plant up. If the area is in the shade the sun is not there to speed up the action of the acid and dry out the plant and they have a chance to recover. Spraying at around noon when the sun is at its highest on a hot sunny day is the best time of day to spray the vinegar as the shadows will be at the minimal point and there won,t be any dew to dilute the vinegar. Alternatively, if there is a time of day the canes are not in the shade and there is no dew try spraying then use it full strength. I have tried diluting it a tad with 5% vinegar but it did not work well at all. The acid removes the waxy coating on the plant and then the sun is free to dry the plant up.

My experiance is that in the long run vinegar does not kill the plant. It turns brown, wilts, and in a week to 10 days the plant is backIt cost me $250 and three applications to find that out

Oh yes, it works amazing. I wondered the same thing. But low and behold the blackberries are gone!

I haven't tried dried blackberry vines, but they should be fine since the diameter is relatively small. If you put something in that is too fat, it basically chokes.

It actually worked pretty good. We sprayed my yard and surrounding vegitation. As the sun went down they mosquitos were less prevelant. The gallon goes a long way. We only used a quarter of it for a very large area. Its only really effective for about 2 days and you have to spray again.

We use it for a grapevine, outdoors, with stakes....and works beautifully - would not know if it would stand alone....

We used a garden sprayer and walked the yard spraying surface. Do be careful on breezey days and do not gt too close to plants you want to keep. This product does work!

That is a good question, I have never used it to spray my hedge's. I have tried it on some vines, the tops die and then come back next year. Maybe your hedge will come back from the base...?

Probably not a good idea. I imagine if it's wet, it's raining, or how are you going to use it? This product is designed to work with direct sunlight. So if it's just getting sprinkled wet occasionally that's probably not a problem, but a deluge of water? No.

I painted the cut of my grape vine last season and so far it hasn't come up this spring. It seem to work!

I cut my super strength vines at ground level. When they died and dried out it was easy to pull down with my hands. I used a product to kill roots at the base so they wouldn't grow again.

It'll do the job, but that's like using a flamethrower to light a candle. I had a similar problem recently and used a small hatchet to cut the vines and a good pair of gloves to pull after that.

I am using it on St Augustine in South Louisiana for Virginia Button Weed. It is working well.

Blackberry "vines" or blackberry bushes? -- Either way, I would use heavy chicken wire or wood or something else more substantial than this net product. Blackberry puts out a heavy branch that is going to put weight on any type of trellis.This netting product provides a support system for light-weight vines, but would probably deform and fail under the weight of blackberries. I'm using it as a temporary trellis to start a Wysteria plant, but I expect that I will have to replace it with wood after the 1st year, because Wysteria grows rapidly and gains weight as it ages.

Sunlight is very bright, so I think it will not work outdoors unless you use it at dusk.

I have purchased this windscreen to prevent invasive neighbors, but I have not have enough experience yet to determine weeds. I believe this fabric is capable of preventing weeds/vines because it just may be a tight enough weave.

Thank you to those who have commented. I was thinking of using this to protect my berry plants from hungry birds. Does anyone think this would be a good (or bad) idea?

It didn't work!! I even tried spraying it on the ground, which worked a little bit better then spraying it on the trees themselves. I suspect that what's needed is the 'professional' sprays which aren't available for home use.
