My Hardiness Zone ?
The USDA hardiness zones offer a guide to varieties that will grow well in certain climates. Each zone corresponds to the minimum winter temperatures experienced in a given area. Make sure that your hardiness zone lies within the zone compatability range of this variety before ordering.

Size & Spacing

Mature Size

When your plant matures, it will be approximately 4 - 6' tall x 12" wide.

Recommended Spacing

We recommend spacing these plants 6 - 8' apart to ensure room for growth.


This variety is self pollinating.

In many cases, you may still want to plant pollinating partners to increase the size of your crops, but with self-pollinating varieties doing so is optional. You'll get fruit with only one plant!

I wanted a seedless variety of grape to replace a tree that had been removed. I was also interested in growing more of our own food.

My mom told me she was interested in having her own grape vine, but due to cancer she hadn't been up for the challenge. Now that she's doing a little better I wanted to surprise her with a good quality plant from a reliable source.

SCOTT B on Mar 12, 2020
I had ordered two of these from Burpee last spring and the deer kept them eaten off as fast as they grew, I even caged them and they still killed them out. I ordered from you this time because you were cheaper and I know that Start Bro's always send a good product.

Christine G on Jan 25, 2020
I like grapes but am less than enthusiastic about grape seeds. I'm hoping I can train them up my grape trellis and maybe in another five years be napping in the backyard under their shade.

I chose the Neptune white seedless grape because I already have a concord grapevine and always wanted a white seedless grapevine.
NOREEN C on Jun 1, 2016
Fat, green, seedless grapes, best snack ever. We have a spot ready for it. Chosen for large fruit size and zone compatibility.

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!
which grapes make good raisins?
Cathy S on Feb 19, 2016
BEST ANSWER: In general we can make raisins from most seedlees grape,but Thompson seedlees is one of the best,Fiesta,Muscat of Alexandria,DOVine and Sultanina make good raisins too.

What is the yield on one vine?
Davey H on Mar 22, 2016
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
what other grape needs to be planted with Neptune?
kathleen m on Mar 11, 2019
BEST ANSWER: They are self pollinating so you shouldn???t have too use any other kind. I planted two plants but both died because of my soil. Too much clay.
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!
I am thinking of growing this in a pot in front of my house so that they can grow up the side. How big should my pot be, and how wide will these vines get? My house has about 10 ft. of usable space, so how many plants can I buy?
TheShadyGarden on Jun 14, 2020
BEST ANSWER: 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" //
Does this grow well in clay soil?
Harold C on Feb 25, 2020
BEST ANSWER: No, I plant two types of grapes and both stunted out. Usually these things
grow like weeds. I never even put in my support structures because they
never got over 18" tall.

What month should I planted in ny?
Gavriel I on Dec 12, 2019
BEST ANSWER: Thank you for your question. Because weather and soil conditions vary so much from year to year and even within your zone, it's best to think of your planting time as a range of favorable conditions instead of an exact time.

You can plant new plants and trees: 1) when the ground is not frozen, 2) when daytime temperatures are above freezing (32??F) and below 90??F, and 3) when extreme weather (blizzard, hail, torrential rain, etc.) is not in the forecast. Be sure to keep plants watered if you're transplanting in warm and/or dry weather.
What would be the pollinator for the Neptune grape vine?
Brandy M on Mar 18, 2019
BEST ANSWER: Neptune is self-pollinating, but for more/larger fruit, another seedless variety like Gratitude would be an excellent production booster.
Can concord seedless and Neptune seedless be planted close together?
Larry M on Jul 14, 2018
BEST ANSWER: Yes, but they do spread and you don't need many to keep you in a good supply
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 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.
Is the Neptune Seedless Grape suitable for planting in tropical countries (like Singapore)? Else, what sweet table grape variety would you recommend? Thanks
Harry on Feb 20, 2016
BEST ANSWER: Thank you for your question. At this time we cannot ship products outside the United States, or to Hawaii. Because of this, we're unable to make a recommendation for your location.

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.
