ABOUT

The plant known as 'Muscat Bleu' is a variety of grape that is cherished for its attractive and productive nature. The foliage of Muscat Bleu is typically lush green with broad leaves that provide a beautiful backdrop for the fruit. The leaves may display a slight toothed edging and are known for their dense, overlapping arrangement on the vine, which can create a thick canopy. The grapes themselves are the standout feature of this plant and are the reason for its popularity. They are typically small to medium-sized and grow in clusters that hang from the vine. As suggested by the name 'Muscat Bleu,' the grapes boast a deep blue to nearly black hue when ripe, often with a characteristic waxy bloom on the surface that can give them a subtle, frosted appearance. The skin of the grapes is relatively thin but protective, and the flesh inside is juicy with a high sugar content, which makes them delightful for fresh eating. The aroma of the grapes is pleasantly fragrant, and they are known for their sweet, musky flavor profile that is reminiscent of the classic Muscat grapes. This aromatic quality often lends itself to an enjoyable eating experience and can also contribute to delightful wines when the grapes are fermented. Throughout the growing season, Muscat Bleu can produce abundant bunches of these delicious grapes, which not only provide a treat for the senses but also add an ornamental aspect to the garden or vineyard with their striking color and inviting presence. The contrast between the vibrant green foliage and the deep blue grapes makes Muscat Bleu a visually appealing plant that can enhance the aesthetic of any space where it is grown.

Toxicity
- To humans
  The common name for Vitis 'Muscat Bleu' is grapevine, specifically a cultivar of grape. Generally, the cultivated grapevine fruit is not toxic to humans when consumed in normal food quantities. However, other parts of the grape plant, such as the leaves and stems, may cause stomach upset if ingested in large amounts due to tannins and other compounds. The grape seeds also contain small quantities of compounds that can be toxic in extremely high doses, but they are unlikely to cause harm when consumed as part of the normal diet.
- To pets
  The common name for Vitis 'Muscat Bleu' is grapevine. It is important to note that grapes and raisins (dried grapes) can be highly toxic to dogs and cats. Ingestion can lead to sudden kidney failure in pets. The symptoms of grape or raisin poisoning in pets may include vomiting, diarrhea, lethargy, abdominal pain, loss of appetite, and signs of kidney failure such as decreased urination. Even a small amount of grapes or raisins can be dangerous to pets, so it is crucial to avoid feeding them any part of the grape plant and seek veterinary care immediately if accidental ingestion occurs.

Pruning

Water
Grapevines like 'Muscat Bleu' require deep watering to encourage strong root development, especially during their growing season. Initially, after planting, water the grapevine about once a week with about 1-2 gallons, allowing the soil to dry out slightly between waterings. As the vine establishes itself, you can reduce the frequency but ensure you provide enough water to penetrate 6-8 inches into the soil. During hot, dry periods, you may need to water more frequently. However, during the dormant season, you should cut back on watering significantly to prevent root rot.
Light
'Muscat Bleu' grapevines perform best in full sun, which means they should receive at least six hours of direct sunlight a day. The ideal spot for planting is an area where the vines are exposed to plenty of sunlight throughout the day, ensuring good fruit set and ripening. Lack of sufficient sunlight can lead to poor fruit development and increased susceptibility to diseases.
Temperature
Grapevines including 'Muscat Bleu' are hardy in a range of temperatures but prefer a temperate climate. The ideal temperature for healthy growth and fruit production ranges from 75 to 85 degrees Fahrenheit during the growing season. They can survive temperatures down to about 20 degrees Fahrenheit during dormancy. It's important to protect vines from frost, especially during the budding and flowering stages which can be damaged by temperatures below 32 degrees Fahrenheit.
Pruning
Pruning is essential for 'Muscat Bleu' grapevines to maintain plant size, shape, and to encourage fruit production. Prune in late winter or early spring before new growth begins when the plant is still dormant. Remove dead or diseased wood, thin out crowded areas to improve air circulation, and cut back each vine to leave only a few buds to ensure a good yield. This should be done annually to promote healthy plants and abundant fruit.
Cleaning
As needed
Soil
The Muscat Bleu grape vine thrives in well-draining soil with a mix of loam and compost, with a pH range of 5.5 to 6.5 for optimal growth.
Repotting
Muscat Bleu grape vines, when grown in containers, should be repotted every 2-3 years to ensure sufficient room for root growth and nutrient availability.
Humidity & Misting
Muscat Bleu grape vines do well in moderate humidity levels; they do not require high humidity environments as typical for many houseplants.
Suitable locations
- Indoor
  Ensure strong light, prune to manage size, and support with a trellis.
- Outdoor
  Full sun, trellis for support, protect from strong winds, winter hardy.
- Hardiness zone
  5-9 USDA
Life cycle
Vitis 'Muscat Bleu', commonly known as the Muscat Bleu grape, begins its life cycle as a dormant vine with buds that swell and burst open in spring, marking the vegetative stage. Leaves and shoots develop rapidly, and following this, the flowering stage occurs, typically in early summer, where small, greenish-white flowers appear and pollination takes place, ideally resulting in fruit set. The grapes undergo berry growth throughout the summer, with the ripening stage being characterized by a change in color and sugar accumulation, leading to mature grapes by late summer or early fall. Harvesting of the Muscat Bleu grapes usually occurs when the fruits reach optimal sweetness, often determined by taste or sugar measurements. After harvesting, the plant enters senescence in autumn, where leaves change color and fall, and the vine moves into a period of dormancy during the winter months, conserving energy for the next growing season. The cycle repeats yearly with careful pruning during dormancy to ensure plant health and productivity.
Propogation
- Propogation time
  Late winter-early spring
- The most popular method of propagating the 'Muscat Bleu' grapevine is through hardwood cuttings. This technique involves taking mature, dormant cuttings from the existing grapevine during the late fall or winter months. The cuttings should be about 12 to 18 inches (30 to 45 cm) in length with several buds on them. They are then buried in damp sand or soil, or placed in a cold frame until early spring to allow roots to start developing. Once the risk of frost has passed and the cuttings have rooted, they can be transplanted into their permanent location. This method is favored for its simplicity and high success rate, allowing gardeners to clone their favorite grapevines efficiently.
