Grapes

Vitis

Grapes are most frequently grown for their fruit which are either eaten fresh, used to produce wine and juices or dried into raisins. Fresh grapes or fresh juice of such, cleanse and purify the body. All species of Grapes are edible but some have better quality fruits than others.
When using Grapes to produce juice and wines, DO NOT throw away the seeds. They make excellent ( and edible ) vegetable oil.
The easiest way to make Grape Juice is with a juicer, then adding some sparkling water.
Wine is most often produced from cultivars of Vitis vinifera; though native North American Grapes can be used as well.
The leaves are also edible and in Mediterranean countries are often cooked for a few minutes and wrapped around fruit. The young vigorous vine tips during late spring into summer also make a great addition to any salad.
Grapes typically prefer full sun on deep, fertile, well drained soil.
Grapes are very easily propagated from cuttings taken while dormant.
The species can also be propagated from seed.
Plants usually take around 3 to 5 years to start producing fruit.
When originally introduced into North America; European Grapes fared poorly due to diseases which affected them which the North American species had natural immunity.
When Phylloxera vastatrix, a disease of American Grapes was accidently introduced into Europe, it killed over 2 million vines devestating vineyards.
Now the choiciest European selections of Grapes are grafted onto disease resistant American Grape rootstock.
Grapes do have some issues that need to be addressed regarding pests and diseases. Some are preventable by clean cultivation and planting the right variety in the right place, others may need other treatments such as spray. For all varieties of Grapes - it is important to remove all old leaves that have fallen during autumn. During summer, thinning some of the foliage to allow sunlight penetration will usually increase harvest, improve ripening as well as helping prevent foliar diseases such as Mildews. Sulfur sprays also prevent disease ( it is recommended to not spray sulfur during extremely hot weather ). Sulfur spray can be used as a preventative - make sure to soak the canopy including underneath the leaves.
Minor defoliation during summer may not cause much long term damage but serious to complete defoliation will weaken and damage the plant well into the future.
Pierces disease is a bacterial disease that affects Grapes in much of the southern U.S. It can cause the leaves to turn brown while the veins remain green then by late summer the stem tips die back, the fruit may shrivel and the roots begin to die. There is no real control other than planting varieties that are resistant.
Vitis vinifera Grapes are very prone to Phylloxera, a sucking insect that damages the roots. It is thus very important to grow Grapes that are grafted on American rootstock in the central and eastern U.S or anywhere else this insect in prevalent.
Keeping vineyards weed/turf free ( increases airflow as well as health of roots ) and mulched ( cools soil and prevents soil splash onto plant ) will also reduce incidences of disease.

Some diseases that affect Grapes are:

Anthracnose - random gray spots in the foliage which dry up, fall out and leave holes in the leaves. Anthracnose may also affect the berries. Prune of damaged twigs and disinfect pruners.

Black Rot - foliage develops circular orangish-brown leaf spots that turn to small, black dots which produce spores if the weather is humid enough.
The berries will turn hard and black.
Spray preventitive treatment of copper fungicide if your crop has had this problem the previous year. Remove and dispose of all infected fruit.

Botrytis Bunch Rot - attacks fruit clusters turning them soft and brown with a brown powdery covering. The foliage may also develop leafspots.

Downy Mildew - foliage develops lighter colored blotches on the foliage. The undersides of the leaves will also be covered in a white, fuzzy mould. The white powder may also cover the stems and fruit clusters.

Powdery Mildew - a gray mold begins to cover the stems followed by the leaves and often eventually the fruit clusters which stop developing.
Thinning vines to improve air circulation may reduce problems with mildews.

Crown Gall - may kill canes. Make sure to use Grape varieties fully hardy in your climate to prevent winter injury. Also be very careful not to damage bark on stems whether trough pruning or cultivation ( there shouldnt be grass at the base of the stems to weed whack to begin with ). Clean pruners ( ex. dip in 9/1 bleach / water mix ) after use to prevent spread of Crown Gall disease if it occurs.

Grapes are long lived - lasting up to 50 years of more. It is important to plant them right the first time. In order to get a good crop, the require full sun on deep, light, well drained soil with an ideal PH of 5 to 6. They are best planted on a slope or near water, to minimize damage from late frosts which can damage the flowers and cause loss of production. It is recommended to plant Grapes during early spring while they are still dormant. Small 1 year old plants establish much more successfully than larger plants. Soak roots in water for 2 hours before planting in a hole large enough to stretch the roots out before backfilling with organically enriched soil. Dust a handful of bonemeal in the bottom of the hole to encourage rapid root establishment. Before planting, prune the vines back but be shure to leave 2 live buds. Grafted vines should be planted with the graft union above ground level.
Too much nitrogen can cause too much growth and too small of a crop. Grapes do like Phosphorous such as is found in Bonemeal. Grapes also love Zinc foliar sprays if zinc is deficient in the soil where you are.
If you are growing grapes on a steep slope where erosion is a problem, use a low cover crop such as Clover rather than mulch ( do not used turf in orchards - it will compete with your crop and cause lower yields ).
Prune in very early March which will allow the cuts to rapidly callous and heal. Grapes can "bleed" profusely from cuts if pruned later during spring.

Hardy to -50 F, surviving in Manitoba, Canada with no damage.

Vitis Van Buren
Vigorous in habit, originating in 1935 in Fredonia, New York.
The mid-sized, sweet tasting, deep purple-black, rounded grapes are borne on dense, mid-sized, cylindrical clusters. The flesh is translucent green and juicy. They are eaten fresh and are best straight off the vine as they store poorly.

powdery mildew. Not known to be damaged by anthracnose, black rot,
Eutypa dieback or Phomopsis cane and leaf spot
Tolerates as low as -20 F

prone to Botrytis bunch rot), crown gall & Phomopsis cane
and leaf spot. Other disease problems are unknown.
