Plant propagation is the practice of creating new plants from old using a variety of techniques such as seed sowing, grafting, taking cuttings, division, marcotting, ground layering, and even tissue cell culture. Some gardeners may wonder why there’s such a wide range of propagating techniques. There are reasons, there are always reasons…

True to Seed or Not?

It sounds ideal to be able to enjoy a fruit or berry, and if we find any seeds, to plant them and create a new plant of our own from which we can harvest the exact same variety of tasty treats. Works fine with tomatoes, as any seed saver would attest to!

Unfortunately, Nature is more complicated than that. Many productive plants are not true to seed, meaning that the seeds from a particular variety of fruit for example will grow into a tree which WILL NOT produce the same fruit as the parent tree, but something which may look or taste completely different.

Why? Plants need to produce genetic variation and diversity in their offspring to ensure survival of future generations. There are exceptions, some plants and trees will grow ‘true to seed’, producing exactly the same fruit or berries as the parent plant, and therefore can be grown from seed, which we’ve discussed in the previous article – The Difference Between Seedling, Grafted and Cutting Grown Fruit Trees.

At this point you’re probably wondering how it works with grapes, so here’s the definitive explanation!

Growing Grapes from Seed?

Grapes come in both seeded and seedless varieties, so it stands to reason that seedless grapes need to be propagated by any means other than seed, and the industry standard method of propagation is the use of hardwood cuttings in late winter.

Seeded grapes do contain viable seeds, and planted in autumn will produce grape vine seedlings in spring. They need to be planted early because they require cold stratification, exposure to cold temperatures which will cause the seed to break out of dormancy.

Sounds good? So what’s the problem then? Well, to put it bluntly, there is a lot of inaccurate, cut-and-pasted misinformation all over the internet, especially on the topic of growing grapes from seed!

Let’s look at an example which is probably the worst offender in this respect, which has been doing the rounds in the Permaculture world for the last decade – enter the ubiquitous Concord fox grape!

Mythbusting Concord Grape Propagation

The permaculture community is quite fond of Concord grapes almost as much as they are of swales and herb spirals, and there are so many discussions centred around growing this grape variety from seed.

What’s so special about this grape you may ask? The Concord grape is a native American grape variety, it’s Vitis labrusca ‘Concord’ which is a different species to the European grape Vitis vinifera. It’s a cold tolerant and tough grape variety which is used for making grape juice and grape jelly. By the end of the 19th century (i.e.e the 1800s), it was the most commonly planted grape in the US. These purple grapes are thick-skinned with large seeds. The pulp, which is sweet, with a strong grape flavour, separates easily from the skin but clings to the seeds. Once the first truly successful commercial grape in the US, by today’s standards of cultivated grapes, it falls way short.

So let’s look at the history of the Concord grape to get the facts straight!

The Concord grape, Vitis labrusca ‘Concord’ is a cultivated variety of the US native wild grape Vitis labrusca hybridized (crossed) with the European grape Vitis vinifera, being genetically one-third of the latter by parentage.

To quote the University of Arkansas, Division of Agriculture, Research & Extension article Plant of the Week: Grape, Concord:

“But by lucky happenstance a resident of Concord, Massachusetts named Ephriam W. Bull (1805-1895) raised a grape seedling in his garden that tolerated the vagaries of the American climate. Bull planted a few native fox grapes, Vitis labrusca, for decoration around his new home about 1840. After raising seedlings from two generations of these plants he selected a form with large fruit he named ‘Concord.’ ”

This clearly tells us that the Concord grape variety was developed from a wild fox grapes seedling, which was then crossed with other wild fox grapes seedlings to produce this cultivated variety. It’s actually the same way all new grape varieties are always produced.

So what does this tell us? Well, to cross seedlings, they need to be different. Therefore, wild, seed-grown fox grapes have different qualities and properties from plant to plant, it’s what we call genetic variation in biology.

What happens if we take seeds from a Concord grape and plant them? We’d create new genetic fox grape variants, WHICH ARE NOT CONCORD GRAPES! They will be some other form of Vitis labrusca or hybrids of them. Think about it, if it was possible to sow fox grape seeds and create the same tasting fox grape, it would have been impossible for Ephriam W. Bull to create a new variety in the first place, as they grapes would never change… And the seedlings are all different, and it really does matter that they’re different, as he apparently had to evaluate more than 22,000 seedlings to find the variety which would be named the Concord grape. If it didn’t matter, he obviously would not have gone to that much trouble!

To throw some more facts into the circle from another credible source, this time from the Missouri Botanical Garden, Vitis labrusca ‘Concord’ article:

“Concord’ will not come true from seed, however, and is propagated asexually (cuttings and grafting).”

Looking up many of the University Agriculture Extension Services, I can only find that grapes are propagated by various means, except by seed, for example, from Agricultural Extension Service, The University of Tennessee article Grape Growing in Tennessee (PB 1475):

“Most grapevines, with the exception of V.vinifera varieties, are grown on their own roots. V.vinifera varieties are especially sensitive to root phylloxera, which is a threat throughout the country. Therefore, these vines are grafted onto resistant rootstocks. American bunch varieties and French-American hybrid varieties may be propagated by cuttings… Layering is the surest way to propagate all grape varieties. How-ever, it is seldom used except for varieties that do not root readily from cuttings, such as with muscadines and Cynthiana.“

Note, the reference to grafting V.vinifera (European) varieties for protection against root phylloxera is only applicable to certain locations and soil types around the world, such as Tennessee in the US. European grapes grow just fine on their own roots in Australia for example, and this is how they’re grown commercially and in viticulture.

This should hopefully settle the matter and clear up a lot of the misinformation on the subject.

Seed Grown Grapes?

To summarize, technically, we can grow grape vine seedlings from seed, but they aren’t the same variety as the parent vine. It’s a genetic gamble on what they will turn out to be, so unless we have plenty of space to waste and are happy to wait at least two or three years to find out what the grapes taste like, it’s kind of pointless, as the grapes may not be very palatable, or may not be edible.

So, unless you’re attempting to breed a new grape variety, don’t grow grape vines from seed, grow them from hardwood cuttings or graft them if they can’t grow on their own roots in your location.

Considering grape vines will fruit for many decades, and are quite cheap to buy, perhaps it may be way easier to just buy a growing grape vine of known variety from a garden nursery! They will pay for themselves many times over in their lifetime.

Want to propagate your own grape vine? It’s very easy.

How to Grow Grape Vines from Cuttings

Grapes can be propagated from cuttings taken in late winter, this prevents the cuttings from drying out during the drier winter periods.

Use year old growth material for cuttings, which has matured at the end of the growing season. The wood at the end of a cane should be well matured and hardened off, without green tips. Cuttings should have at least 3-4 buds, but not more than 6-7. A good length is around 30cm (12”).
To identify the top and bottom of the cutting, cut the top fairly flat and the bottom end (root side of the plant) at a sharp angle, as the cuttings won’t root if planted upside-down! It also makes it easier to push them into the propagating medium.
Dip the bottom ends of the cuttings into rooting hormone – this is optional and not necessary.
Fill a deep pot with a suitable propagating medium such as potting mix (or dig a narrow trench in the ground and loosen the soil if propagating in the ground). TIP: Coconut coir also works really well as a propagating medium.
Take each cutting and push it into the propagating medium so that only the top two buds are unburied.
Keep the propagating medium/potting mix barely moist and locate the pots of cuttings in a sheltered, protected location which preferably gets morning sun and dappled midday sun to prevent the cuttings from drying out when the leaves first emerge in spring.

You can also take very short cuttings with only one bud known as vine eyes. Make a cut 6mm (1/4”) above a bud, then make another cut 5cm (2”) below it to complete the cutting. It’s a way of making a limited amount of propagating material go much further to produce more cuttings.

Note: vine eye cuttings with their single bud only do not take root as easily as the larger 3-4 bud cuttings.

When propagating grapes, it’s more efficient and productive to put many vine cuttings into a larger wide container, rather than potting up cuttings singly.

When the cuttings put out their new leaves and begin to develop a decent root system, they can be transplanted into their own pots and left to grow on there. Don’t be inpatient and attempt to repot the cuttings too early, as too much root disturbance can cause the cuttings to fail. It is advisable to let the cutting grow in their pots for a year to develop really strong roots before planting them out into the ground in late winter.

I just wrote about this in regard to citrus and avocados, which are not only genetically variable, but start from seed with juvenile growth. Some citrus seedlings can be nasty with thorns!

1. Yes, the trifoliata citrus rootstock (Poncirus trifoliata, or trifoliate orange) has shocking large thorns. You sometimes see gardens where the citrus tree has died above the graft and the rootstock has taken over, or the rootstock has thrown up suckers which have overgrown and taken over, it’s just a horrible thorn bush!

  1. Oh, that is a nasty one; and some grow it as an ornamental! That seems crazy to me. Supposedly, it is quite striking if pruned to expose the branch structure and thin it out a bit, but those who grow it never seem to get around to pruning it. I have never seen a pretty one.

2. Hi, when and how do you plant grapefruit seed?

  1. Hi Jackie, you would plant grapefruit seed in early spring, and you can find instructions here – How to Sow Seeds, Step by Step

  2. Technically, grapefruit seed should be planted as winter ends, early in spring. Even though they are a hybrid, many produce a few viable seed. HOWEVER, they are genetically variable. There is n way of knowing what the fruit of seed grown trees will be like until it actually develops. Grapefruit cultivars were selected from MANY such seedlings. Most others were rejected because they were not so desirable. Most citrus seedlings are very thorny for the first few years. That is how their juvenile growth is. However, some grapefruit seedlings are supposedly not as thorny as other citrus, or are not thorny at all. I have seen some that look like the adult growth of mature trees.

I grow vines from cuttings every year with nearly 100% success. This year I am attempting to grow vitis vinifera shiraz seeds to become vines in order to eventually detect the difference in the fruit. But the trial so far has only produced cotyledons. There is no sign of any vinifera leaves. I am at 75 days since the first shoot broke free of the soil. Has anyone got first hand advice on the time required to produce a varietal leaf?

I have had trouble finding seeded fruits and melons however I found some red seeded table grapes. As I enjoy these alkaline delicacies I wondered if it would be beneficial to keep the seeds at all–you know to make an earnest attempt at growing seeded grapes. Based on your article here I believe the answer is no. Please confirm if this is correct.

Sidebar, why is it so difficult to find seeded fruits/melons specifically oranges and watermelons?

1. Hi Tyra,
  
  The answer is definitely no, grapes can’t be grown from seed to create the sane variety, because they’re not true to seed.
  
  To answer your second question, the reason why it may be hard to find seeded fruit is because seedless fruit are popular with consumer markets these days, and the lack of seeds is considered a positive selling point.

I totally do NOT agree with your opinion that growing grapes from seed is “space to waste.” It sounds like you have never even tried it, so are no expert. Of course the “professionals” won’t recommend it because if we all did it we wouldn’t need them. They are protecting their profession.

I have grown near 1000 from seed. Many die from disease when young, so they save space for others (I don’t spray them because I want more resistant grapes). So far, in 3 years I have 5 very resistant seedlings, two of which have fruited. Nothing else but wild grapes grow in our area (tropical Costa Rica with 150 to 250 inches of rain). I love growing grapes from seed.

1. Sorry Jesse, but it’s not a matter of agreement or disagreement, it’s a matter of science, as I have explained. Seed grown grapes are not “true to seed”. If you have a Red Globe grape for example, like eating that variety, and want to create more grape vines of that variety, you don’t grow it from seed, because it won’t be a true Red Globe grape, but some genetic variation of it. Also, what happens if you wish to propagate seedless grapes? Doesn’t work, does it?
  
  I explain clearly in the article how you propagate grapes properly, using dormant cuttings taken in late winter.
  
  The way the ‘professionals’ protect their trade is by using PBRs, or plant breeder’s rights, they’re like plant copyrights. which only allow licenced growers to produce a certain grape variety for many years. Look at all the fancy new varieties such as the long “Ladyfinger” varieties, the plants won’t be available to the general public for a long time, perhaps a decade!
  
  If you’re happy to eat any type of grape, and you are fortunate to have lots of space to grow random grape varieties that can vary considerably in quality, and there is demand for your produce, then I encourage you to keep doing what you’re doing.
  
  Many growers need specific varieties, such as wine makers using the very popular red wine grape Cabernet Sauvignon. The variety determines the flavour of the wine produced, they can’t mix varieties.
  
  Also, for many urban growers like me, with limited space, we need to make the best use of the space we have, and want to grow things with known qualities, how resistant they are to disease, how productive they will be, what conditions they prefer and what the produce will taste like.
  
  You’re obviously on a farm to have that many grapes. If you want to keep experimenting, that’s fine, but if you have managed to grow grapes that are very disease resistant and taste really good, I can offer some advice that might be helpful. You’ve developed a new variety of grape, it’s your own, and if it’s worth growing, take cuttings in late winter, and grow more of that one, because it has the qualities that you like. If it grows well in your area, either share the plants or sell them to other people around you so everyone can have them!
  
  Incidentally, with that much rainfall, in the tropics, there is so much tropical and subtropical produce you can grow! 150-250″ of rain a year is so much, we only get around 30″ a year here… 🙁

I had a Concord Interlaken cross that had the taste and seeds of the Concord, the early summer ripening and color of the Interlaken, and did very well dry farmed. In my experience most will produce good grapes, even if not exactly like the parent. A few won’t fruit at all.

Life would be incredibly boring if we were all exactly like our parents.

1. Hi Lauren, if people have the space and the inclination, then experimenting can sometimes yield positive results. Many commercial grapes are crosses of older varieties. That’s how new varieties are created! Sometimes people want to grow the same grape variety as the parent grape, in which case growing from seeds would be the wrong approach and only lead to disappointment. It depends on what the goal is. 🙂
