May 15, 2012Q.When to kill grapevines most effectively
I would like to know at what time of year will it be more effective to cut a grapevine, apply Roundup and Ensure that it doesn't sprout back. Spring or fall?

Certified ExpertA.Spring is the very best time, but hot days in the middle of summer are a close second.
The easiest way to kill gravevines with Roundup, is to cut the vine, completely if you can. Paint the cut with concentrated Roundup. When the plant is in full growth mode (spring) or is trying to keep up with the heat (hot days), its vascular system is in overdrive. When it gets cut, it does not realize it right away, so adding the Roundup causes it to suck it into its root system and kills it.
With tough vines like this, you may need to repeat it 2-3 time, but it is the fastest way to kill the vine.

May 21, 2012Q.Grapevine Leaf Rust and Die Off
I have a Concord grapevine and it does not seem to be doing very well. The leaves are curled up and indicate a rust color. Normally by this time of year, the leaves are large and green, and I see groups of grapes starting. Very concerned that I will lose this plant, which has been here for about 35 years!

May 26, 2012Q.What causes the grapes to dry up and fall off the vine
The grapes on my muscadine grapevine, (Black James grape) fall off the vine when they are still very small. It seems like they just dry up and fall off. The vine is loaded with baby grapes but they do not reach maturity.

June 3, 2012Q.Older Grape Vines
We have three grape vines that have been in our yard for about 20+ years. I took over the "garden" a couple of years ago. Every year late in the fall we cut back the grapes. We get a lot of new growth each year but no grapes! Are the plants just too old to produce? Or do they need something?

Certified ExpertA.Even plants can eventually "poop out". Stress on the plant will also affect the productivity of the fruit. Make sure that the soil is balanced. I would recommend having it tested, if you have not done this before. Then add amendments based on what the soil is lacking. And lastly, make sure that there are no pests or fungus affecting the vines. If there are, treat the plants accordingly.

June 15, 2012Q.Why are the leaves on my baby grape vine turning brown?
Last June I bought a 'Chardonnay' grape as a foot long stick with roots. I planted it in a large dust bin, with good drainage and a light application of lime to the potting soil. I put the dust bin in the conservatory (I live on the west coast of Scotland) and for the first summer the vine put out leaves and grew a bit of stem. Over the winter it went sort of dormant, the leaves dried up and mostly fell off and I thought all was well. Come the spring, the vine grew a good 8 inches and there was a great crop of tender green leaves. We had a hot spell of a couple of months this spring and I provided shade for the grape, and kept the soil reasonably moist. Then the newest leaves began to turn brown, then the larger ones. I thought it might be too hot for the grape and moved it to a sheltered corner outside. The leaves continued to turn brown and fall off, and now a few of the leaf stems and tiny twigs are following suit. A few small new leaves are emerging, but they turn brown almost as fast as they grow. The plant is not a vigourous grower. I have never grown a grape before. What am I doing wrong?

Certified ExpertA.It sounds like a fungus is attacking the plant. I would treat it with a fungicide and that should clear it up.
