Grape - Table

Table grapes generally produce higher quality fruits when the climate is warm and dry, with a long growing season. Winters must be long enough to ensure a dormancy period, but there should not be late frosts that pose a threat to the young buds. The most important soil characteristics for this crop are good internal drainage and adequate depth (minimum 75 cm to 1 m) with no impeding layers (shallow bedrock, chemical or physical hardpans).  It is recommendable to avoid growing grapes in clay soils because that may cause poor drainage and salt accumulation. Grapes are fairly tolerant to a wide range of soil pH, but do well in a pH of 5,5 to 6,0.
