When do grape vines produce grapes

As easy as they are to propagate and given that the deep rooted plants are drought tolerant there may be a case for growing them for biomass. I've been growing Vitis coignetiae - Crimson Glory Vine in our hedgerows in the market garden for about six years and the plants are really starting to take off now. The plants have not borne fruits but we do receive a decent yield of biomass that I use to mulch the surrounding productive shrubs and being a climbing plant they take up no extra space.

Medicinal uses - There are many medicinal uses recorded for grapes;. The second year after planting they should start producing fruit and after three years you can expect up to 7kg 15 lbs of fruit per vine. Two vines are probably enough to support a household of grape lovers and as the vines mature will produce enough fruit for juicing as well as eating fresh.

For juicing and wine making you can expect approx. Grapes are good candidates for use in polycultures, the vertical climbing nature of the plant and its adaptable form when pruned provides many opportunities to combine the grapevine with other plants. Growing grapes in multi plant polycultures is probably only worth considering for small scale garden polycultures and for people wanting to get creative in the edible garden.

We've been growing various grape polycultures for almost 10 years now. For one polyculture the grapes are grown m high with a variety of herbs, shrubs and trees grown around. We've also planted a new polyculture this year featuring grapes trained on wires and we'll see how it gets on. Below you will find a brief description of our grape polycultures. I'll be writing full profiles of these polycultures for a book I'm working on that should be ready in a few winters time.

Grapes trained on wires Polyculture We have been training grapes in polycultures around the gardens this year but as they have not matured yet, I'm not sure how effective they are. This design is planted on the berm of an overflow swale that catches overflow from our reservoir. The vines are planted in the middle of the swale and trained onto two wires Kniffin system. In front of the vines are Vaccinium corymbosum cv. Grape Polyculture - Large Arbor We inherited some wonderful old vines when we bought our house, they must be at least over 50 years old now and produce a great quantity of grapes each year.

The vines are grown up a large arbor that is approx 3m high and there is around 30m 2 of arbor. The vines also grow up the face of the house and onto a balcony on the top floor. Underneath the vines we have variety of plants growing including the plants listed below.

Here's a short list of shrubs, herbs and bulbous plants that I have observed growing well under and alongside our grape vines. I planted a climbing Akebia quinata - Chocolate Vine beside one of the vines in our yard. I can't recommend this combination as the Akebia growth will eventually strangle the Grapevine as it matures and the Akebia, while not being pruned every year, is starting to dominate the arbor and reducing the light the vine receives and very few grapes grow in this area now.

I believe there is good potential for grapes in agroforestry systems. Being suitable for growing vertically and trained to wires they require little space and can easily fit between rows of timber or coppice trees taking full advantage of light while the trees are growing. Spacing should be considered so that when the tree rows are mature and ready for cutting they will not shade the light demanding grapes. It is also possible to grow grapes within tree canopies but harvest will be difficult, pruning will be near impossible and the shading provided by the vine on the tree and vice versa may reduce the productivity of both species.

It would certainly be more of an attractive option on a very small scale at lines of latitude north or south below 40 where light is more abundant.

This cultivars was created in Kishinev Institute of Vine and Wine in Moldova and is a delicious dessert grape that ripens during the last half of September depending on the conditions under which it is grown Fruit - The grape shape is conical and midsize with the average weight of each cluster being g. The skin is usually thick and the flesh is firm.

The fruits can be eaten fresh and can be stored for months under refrigeration. The grapes also keep well on the vine, providing birds do not get them. Growth Rate - The vines are vigorous and are very suitable for growing up a tall trellis with plenty of room for the shoots to grow horizontally.

Plants that are years old, when properly cared for, can be expected to yield kg of grapes. Fruit - Naslada ripens in the second half of September. The weight of a bunch range from g. The fruits can store for long periods of time when refrigerated. Growth Rate - The vines are vigorous and require little fertility Soils - Best grown in soils with pH 5.

Overview Latin name - Vitis vinifera Common name - European Grapevine Family - Vitaceae History - The grapevine family, Vitaceae, is believed to be over 65 million years old and would have initially spread around the globe by continental drift long before us humans arrived on the scene.

Vitis vinifera leaves and tendrils Sexual Reproduction - The plants are hermaphrodites with each tiny flower containing both male and female reproductive structures. The time to prune grapes is when they are dormant from December - February, depending on your location.

I prefer to prune in Jan or Early Feb as I have noticed the vines can weep water droplets fall from the cuts when pruned too late in the year. For our vines, grown on an arbor, I use a sharp pair of secateurs always Felco and I'll cut back last year's growth to two or three buds, making a cut just above the bud. The white spots in the below image indicate where the cuts should be made when pruning. The insects were imported to Europe with the American vine species Vitis labrusca and although causing little significant damage to the American vines that had evolved several natural defences against phylloxera, they ravaged through the defenceless European Grapevine.

The best way to defend against this pest is to use grafted cuttings on resistant V. Flooding the vines for 50 days in winter has also been used and will kill all the nymphs that overwinter in the roots or the bark at the bottom of the plant.

Another insect, the Vine Erinose Mite - Colomerus vitis causes parts of the leaf to bulge upwards, appearing blistered and can superficially look similar to D. Disease : Fungal — The most common diseases of grapes are fungal.

Black spot, powdery mildew and anthracnose are some of the common fungal diseases that affect the plant by reducing its capacity to harvest light via leaf loss and leaf deterioration. Choosing resistant cultivars and keeping the plants well cared for i. Disease: Bacterial — Bacterial grapevine diseases are more common for broad scale monoculture grape cultivation and should not be of concern to the home grower given proper cultivar selection and care for the plants Early Autumn Frosts : During autumn the vine is redirecting nutrients from its leaves to store as reserves in the trunk and roots.

An early frost can disrupt this process with the leaves falling to the ground early resulting in less nutrition for the plant and possibly leading to weaker growth the following season.

Extreme Weather Events : Hail and strong winds can defoliate a vine in early spring and lead to poor flower development and reduced fruit set by way of reduced carbon assimilation and storage. Our vines are subject to spring hail and some pretty strong storms with obvious damage caused, but we always receive a good crop. In the winter, most grape vines can tolerate a temperature of -7 degrees Fahrenheit In the spring, after the buds break, the temperature tolerance is For more information, check out this article on grape cold hardiness from the Washington State University Extension.

In fact, a bit of drought stress can encourage them to grow stronger roots systems. Slight water stress can also cause the grapes themselves to be a bit sweeter.

Significant water stress, caused by long periods of drought, can become worse in gardens with dry soil. If you have a problem with dry soil, check out my article on dry soil. On the other hand, over watering can also spell death for your grape vines, due to root rot or fungal diseases.

Over watering can also slow root growth and leach nutrients out of the soil. For more information, check out my article on over watering. Before you plant a grape vine, add some compost to your soil. It will provide organic material and nutrients for your grape vine as it grows. The best part is that you can make compost yourself from ordinary yard and kitchen waste! For more information, check out my article on how to make your own compost. It may be necessary to use fertilizers as a supplement to compost, in order to provide extra nutrients if you soil is lacking.

The best way to tell if you need fertilizer is with a soil test. For more information, check out my article on soil testing. In general, grape vines should be fertilized rarely. If you do need to fertilize, use a balanced fertilizer such as To learn more about fertilizer numbers and what they mean, check out my article on NPK ratios. A soil test will also indicate the pH of your soil. The ideal pH range for grape vines is between 5. Finally, remember that it is possible to harm or kill your grape vines by over fertilizing them.

For example, too much nitrogen can prevent your grape vines from producing any fruit. For more information, check out my article on over fertilizing and my article on low-nitrogen fertilizers. Pruning is very important for grape vines. Grapevines can grow in partial shade, but they are unlikely to produce much fruit unless they get a significant amount of sun - up to seven or eight hours per day.

This is also why neglected vines don't produce many grapes. The upper level of leaves often shades lower levels, keeping the leaves from absorbing the necessary sunlight to help the plant develop fruit. Once grapes appear, sun helps them develop more sweetness. Grapevines require well-draining soil to keep the root system healthy. Without strong roots, the vine can't develop fruit. Grapevines prefer loamy soil, but they can survive in denser soils as long as the grade allows it to drain properly.

Tiny bunches of grapes often appear in late spring as the blooms begin to disappear. In Mediterranean climates that tend to have cooler spring weather, the grapes might not ripen until mid to late summer, sometimes into early fall. Grapes usually develop their color and size long before they are ripe, so you can't use your eyes to tell you when the grapes are ready.

Instead, give them a taste. Pop off a grape from a few bunches scattered around the vine and taste them for sweetness. Once the grapes reach the taste you like, it's time to harvest them.
