Popular table grape!

Medium-size round grapes are dark blue and virtually seedless. A distinctive sweet musky taste makes it a perfect grape for fresh eating. Ripens in early to midsummer. Zones 4-8. 

​Grapes prefer a well-drained soil. Gravelly or sandy loams are excellent. A clay loam will do if not too heavy, but wet or heavy clay soils are not good types for grapes. Grapes will prosper if the soil is rich in organic matter. As organic matter breaks down it provides the nutrients for growth. A mulch of shredded bark or leaf mould helps to maintain soil moisture and eventually adds to the organic content of the soil. The acidity level of the soil should be tested. Most Maritime soils will need lime. A pH level of 6.5 is ideal.'

​The year of planting , prune your plant lightly, if at all.  A rule of thumb, leave approximately 20-30 buds per plant. As the years go by you may leave somewhat more wood each spring, however the plants should be pruned hard to produce large clusters of quality grapes. By pruning, you limit the number of fruit buds and those that remain receive the entire vigour of the root system. If you do not prune, you will end up with many grapes, but they will be small and lack sweetness. If you are growing your vine over a trellis for ornamental purposes, prune more lightly, thinning out weak canes rather than cutting them back.

​The most common mistake of the new grape grower is to pick the grapes before they have reached optimum ripeness. Remember that once picked, grapes do not get sweeter. Because a grape turns color, it does not mean it is ripe. The sugar content gradually rises in the fruit. Unless you have a device (refractometer) to test this sugar level, the best way is to sample frequently. Once ripe, snip the clusters off with pruning shears. Handle carefully so as not to injure the berries. Grapes can be kept several weeks if kept at refrigerator temperatures.
