General description: The Venus cultivar was created in the USA. Its fruit are versatile and can be consumed as table grapes or used to make wine. The lack of seeds in the grapes is an added advantage. The Venus grapevine grows strongly and can easily reach up to 8 m in height. It’s resistant to frost and diseases so even a novice gardener can manage its cultivation.
Fruit: This grapevine produces medium-sized grape bunches. Its fruit are big, round, and dark navy in colour. Its grapes are exceptionally juicy, sweet, and delicious. This is a seedless cultivar.
Ripening: Venus grapes ripen in the second half of September.
Leaves: Venus has quite large, lobed, green leaves that change colour come autumn.
Cultivation requirements: This grapevine requires a sunny and warm location. It prefers fertile, permeable, slightly moist soil, and doesn’t like heavy, wet substrates. Ideally, the substrate should have a slightly acidic pH. Seedlings should be planted every 1-1.5 meters, 10-15 cm deeper than in the pot they came in. Very small seedlings should be planted in a shallow hole and only covered wholly with soil in autumn. This significantly increases the frost resistance of grapevines and increases the efficiency of watering freshly planted vines.
Care: To build a powerful root system, grapevines need a lot of water. Caring for a newly planted seedling is basically limited to systematic watering. It is especially important to pay attention to watering in early summer and as the grapes ripen. Each young vine requires up to three buckets of water per watering, but the soil must not become too waterlogged.
Pruning: In the first year after planting, it’s recommended to keep only one to three stems. In the following years, trimming depends on how the vine is to be shaped. Thinning out in order to obtain high quality fruit is advised. Generally, stems should be pruned strongly, and care should be taken whilst selecting which stems and shoots are to be cut, to leave well-fruiting ones on the plant. It is best to leave pruning until late winter (near the turn of February and March) or in summer during vegetation.
Props: This grapevine is perfect for growing on all kinds of fences, pergolas and arbours, trellises and other garden support structures.
Overwintering: The Venus grapevine withstands temperature drops of down to -28°C, however it is recommended to protect the plant for the winter (for e.g., by using agrotextiles). At the beginning of November, cover young seedlings by piling a mound of soil with peat about 30 cm in height over the plants. This not only insulates them from the cold, but also shields them against flooding during the thaw.
