Red, White & Blue Seedless Grape Vine Collection

I am in zone 6 and the standard 2-wire 4-cordon system works well for all our grapes.

I do not remember if there Is a “recommended” trellis system for the red, white, and blue vines (although I did read as much as I could get off the Internet and from Stark). We also took a vacation in Portugal and visited three or four vineyards where I was able to measure spacing and see various trellis approaches.

We went with a simple, single wire trellis that occupies a raised bed next to two walls (facing south-west) of a barn that was torn down several years prior to planting. The wires are embedded in the wall of the old barn and supported by several metal posts that help to keep the wire about 4’ high above the raised bed. The vines are spaced apart about 7’ each except at the end where I gave the single direction vine a bit more room.

Based on what I’ve read and seen, I think any system you like can be pruned to work. For us, the simple approach fit perfectly.

Best of luck - and BTW, you’ll be surprised at how much pruning you need to do. It’s fun, though.

Depending on soil, it could take 2 seasons

"Soggy" is the largest problem. Grapes like moisture but too much will kill them.
The clay can be modified by adding organic material, compost, topsoil, etc.
Adding bio-char, which is absolutely nothing but charcoal, will help the clay to drain the water.
I am going to move two of my vines because the water table where they are is too close to the surface, but not "soggy". (and it's only 40 feet from two other vines along the same fence which are thriving).

Thank you for your question. It's wise to be in the habit of doing an annual soil test; all plants drain nutrients from the soil during the growing season and need to be replenished. Another cause could be a lack of proper pruning. If you're just letting the vines grow wild, too much of the plant's energy is going to the vine and not enough to the fruit. Also, selectively thinning fruit will produce bigger remaining fruit in most grape varieties.

If you are able to vent the greenhouse to keep it from getting too hot it may work. You might also try shade cloth. Our hoop house in upstate New York can reach over 115 degrees in the blazing sun if we don't open up the ends and use shade cloth.

We recommend you try a scratch test: //www.starkbros.com/growing-guide/article/how-to-do-a-scratch-test
If that test determines the tree is no longer living and in need of replacement, please contact our Customer Support Team at 800.325.4180. They'd be happy to help.

Thank you for your question. The age and size information for our grapes is as follows: 4” pot: 6-12 months old and 4” tall bare root: 1 year old and 12-18” tall. Our grapes will typically take 2-3 years after planting to reach maturity and bear fruit.
