I chose the Neptune white seedless grape because I already have a concord grapevine and always wanted a white seedless grapevine.

Fat, green, seedless grapes, best snack ever. We have a spot ready for it. Chosen for large fruit size and zone compatibility.
Bright D on May 16, 2016
My father-in-law grew grapes and my son loves grapes so I decided to give it a try at my own home and love seedless grapes myself so we will see, hopefully will have a very hearty crop for future eating pleasure especially for my granddaughter and our family's dining pleasure.

what kind of trellis would work best for the neptune seedless grapes?
Heather on Feb 1, 2017
BEST ANSWER: The Neptune vines grow very fast, spread wide, and have large diameter branches. They need lots of room to grow, and a sturdy trellis to support them. I use 16 foot long cattle panels that are 50 inches tall, connected with 'T' posts. The wire on the panels is close to the thickness of a pencil, so there is plenty of support with no need to beef it up later when the vines grow out of control. I would keep the vines at a MINIMUM of 10 feet apart. Even at that spacing, by year two and beyond you will have to be vigilant to keep them trimmed back. I have 12 varieties of grapes, and the Neptunes by far outgrow the rest. Good luck!
I am a total newbie. I want to try growing some grapes, i have a 5ft high chain link fence that i was hoping to plant them up against. Could i use that as the basis for an initial trellis and then add additional support as needed? if so how and what would you suggest i add or how. Money is a factor. Thank you.
Troy D on Oct 3, 2017
BEST ANSWER: We are new to grapes as well, but we learned a lot the hard way. I don't recommend a chain link fence, as once even a young grape vine gets hold, it will not let go. A 2-foot vine latched onto some temporary fencing, and it was easier to cut the fence down with heavy wire cutters than try to cut the strong-as-iron grape tendrils!

Your permanent trellis must be seriously heavy and strong, or your vine will ultimately destroy it. We designed and built our own really simple pergola with 4x4 cedar posts and cedar 2x4s for the top. Super-solid, and cedar lasts for the decades your vine will be there. You could initially get away with a flimsy pole for the first year, but it would definitely have to be replaced by something strong by the next season or so.
do you get grapes the first year or longer?
sarah s on Sep 21, 2016
BEST ANSWER: We got a small amount the first year, and more this (second) year. Expecting more in the coming year. Good luck!
what kind of soil do these grapes like?
Dave J on Nov 12, 2017
BEST ANSWER: I planted mine in compost and they have done well...
How many plants for a 4' x 8' raised bed?
Rae P on Aug 1, 2017
BEST ANSWER: That is a rather small bed for multiple grape vines, but if you're willing to stay on top of pruning them, it should work. While this is a little closer than what we normally recommend (which is 6-8' apart), you could probably get away with planting either two Neptunes (or a Neptune and another seedless variety for more/bigger clusters on both vines) about 5' apart (1-1/2' from the end of each long side).
What size will the vine (Bare Root) be when it arrives at my home?
Dyrles on Jan 29, 2017
BEST ANSWER: Thank you for your question. The age and size information for our bare-root grapes is as follows: 1 year old and 12-18??? tall. Our grapes will typically take 2-3 years after planting to reach maturity and bear fruit.
How's it done without any seeds?
Frank T on Oct 8, 2016
BEST ANSWER: Thank you for your question. The vine is grafted, as are most all of our plants and trees. That ensures that the true parentage of the variety is what you get.
Would you recommend cane or spur pruning for this grape? Thank you
22sky@live.com D on Oct 3, 2016
BEST ANSWER: Thank you for your question. Because it's an American hybrid, we recommend cane pruning, which help lower disease probability.
What is the yield on one vine?
Davey H on Mar 22, 2016
BEST ANSWER: Hi Davey,
I planted Neptune vines for their excellent quality ,Nepune productivity is moderate,in large vineyard is about 6 T/acre ,it means about 22 pound per vine,we can increase the productivity if we have only few vines,

I hope ,my answer is correct
Best wishes

Is the Neptune Seedless Grape suitable for planting in tropical countries (like Singapore)? Else, what sweet table grape variety would you recommend? Thanks

So far, so good.
So far, so good. They look healthy and have tiny clusters of grapes. I wasn't sure when I saw my complete order come bare root. Didn't look like much but everything without exception has taken off and is doing great.
