Concord Seedless Grape Vine

Concords grow well here in Mid-Missouri with lots of clay soil. I have grown both seeded and seedless concords all my life (I'm 77) and they are delicious and make great wine.

Yes that system does work but I feel the vines do better and also a better yield when the roots can run with more room to spread out in the ground

You can do either, your preference.

Geneticists have been trying to cross-breed Muscadine and bunch grapes for decades. Generally, while they do have some homologous chromosomes, any successful crosses were sterile. A better question might be should you try growing bunch grapes in the southeast? The disease pressure and pest pressure is very high where muscadine thrive. So, while it may be remotely possible to have a seeded crop one year, the pressures of disease and pests limit your potential success. It will not cause your bunch grapes to be permanently seeded, if at all. Reliance is self-pollinating which further reduces a seeded crop one year, but it will definitely not alter the genetics of your seeded bunch grapevines. They will remain seedless. If you’re concerned about seeded grapes on your Reliance vine, as unlikely as it seems, you can bag the clusters when the flower buds appear. Once the flowers close you can remove the bags. If it were me, I wouldn’t worry about cross-pollination. But then I wouldn’t grow bunch grapes where muscadines like to grow. Muscadines are more disease and pest resistant than bunch grapes.

It requires more work, but if you're already familiar with Vertical Shoot Positioned training, then you certainly can. One benefit would be more exposure to light, which helps reduce risk of fruit rots in humid areas.

I do not know what your clothes line is made of. I use #9 gage wire strung on "T" post 10 feet apart, with a grape vine centered between the posts. These vines get very heavy and the end post need good bracing. My wires are strung at 3 feet and 5 1/2 feet from the ground.

Yes they should with easy & some gentle guidance. Mine in 1 yrs grew to the top of a 6' fence. Hope this helps

Hi George, Its best to keep your seeded grapes planted away from seedless types. They could cross pollinate and your seedless might develop tiny seeds.

It is not recommended; however, it is possible for certain plants to be planted in a zone outside the recommended planting zones. If you are willing to take extra precautions and care to safeguard your plant's health, then by all means give it a try! You'll never know unless you do!
Grape vines are very sturdy and vigorous... if you ensure the protection for the young plants until they are well established! I have noticed with my specific location - zone 7B, I can maintain citrus and subtropical plants - but I really have to pay attention to the weather and keep a check on the plants daily when the weather is uncertain!
It's no different for you in your 4B zone. Because you are planting a cultivar, you will need to "baby" this plant, but it's always worth the extra effort when you finally get a bountiful yield!

**Note - If there are vineyards or even wild grapes (muscadines) growing in your area, then you should be fine to grow these grapes in 4B zone.

You can grow almost anything in a container! This excellent article will answer your questions and provide good advice. Please see "Growing Fruit Trees in Containers" //www.starkbros.com/growing-guide/article/fruit-trees-in-containers-pt1
