ABOUT
The 'Jonkheer van Tets' is a popular variety of red currant, known for its vibrant, glossy red berries that hang in clusters from the plant. This deciduous shrub has a bushy nature with multiple upright stems. The leaves of the red currant are typically a bright green, with a subtle sheen and a lobed appearance, resembling a rough maple leaf shape. They are arranged alternately along the branches. During the spring, the plant produces modest, yet numerous flowers. These are small and arranged in racemes, which are hanging clusters that later develop into the fruit for which the plant is known. The flowers are generally greenish-yellow or sometimes have a reddish tinge. As summer progresses, the berries ripen to a deep red and are typically ready for harvest in early to mid-summer. The berries are juicy and tart, making them a favorite for culinary uses, such as in jellies, sauces, and baked goods. The juxtaposition of the bright fruit against the foliage creates an attractive display that can be both ornamental and practical for gardeners who appreciate both beauty and yield in their plant selections.

WaterFor the red currant 'Jonkheer van Tets', it's important to water regularly to maintain evenly moist soil, especially during dry spells. Water deeply once a week with about 1 to 1.5 gallons of water, depending on rainfall and soil conditions. In hot climates or during periods of drought, you may need to increase watering to twice per week. Monitor the soil moisture by checking a few inches below the surface – the soil should feel moist but not waterlogged. During the winter dormant period, reduce watering since the plant's water requirements will decrease.
LightThe red currant 'Jonkheer van Tets' thrives best in full sun to partial shade. Planting in a spot that receives at least 4-6 hours of direct sunlight a day will ensure good fruit production and plant health. Avoid placing the plant in deep shade, as this can reduce flowering and fruiting.
TemperatureThe red currant 'Jonkheer van Tets' performs well in a wide range of temperatures, but the ideal temperature range for growing is between 60 to 75 degrees Fahrenheit. It is hardy and can withstand winter temperatures down to about -40 degrees Fahrenheit, making it suitable for northern climates. During the growing season, ensure that the plant is not exposed to prolonged temperatures above 85 degrees Fahrenheit, which can stress the plant.
PruningPruning the red currant 'Jonkheer van Tets' is essential for maintaining plant health and encouraging fruit production. Prune in late winter or early spring before new growth begins, removing dead or damaged wood and thinning out old branches to allow light and air to reach the center of the plant. This encourages new growth, which is where the fruit will form. Prune annually to keep the plant productive and well-shaped.
CleaningAs needed
SoilRibes rubrum 'Jonkheer van Tets', commonly known as red currant, thrives best in a well-drained, fertile loam with a pH between 6.0 and 6.5. A mixture of garden soil, compost, and peat or a well-rotted manure can provide the appropriate nutrients and structure. Adding perlite or sand improves drainage.
RepottingRed currants, such as 'Jonkheer van Tets', do not typically require frequent repotting and are generally planted directly in the ground. However, if grown in containers, repotting every 2-3 years or when roots become pot-bound ensures healthy growth.
Humidity & MistingRed currants like 'Jonkheer van Tets' prefer outdoor conditions with natural humidity. They do not require high humidity environments; average outdoor humidity is sufficient for their growth.

Life cycleThe Red Currant 'Jonkheer van Tets' begins its life cycle when seeds germinate in moist soil conditions, leading to the emergence of seedlings. These seedlings develop into young plants with a root system, stems, and leaves, entering the vegetative growth stage. The plant matures and reaches the flowering stage, typically around spring, when it produces clusters of small, greenish-white flowers that are pollinated by insects. After pollination, the flowers develop into bright red berries, which ripen in mid to late summer and are the reproductive fruiting stage of the plant. Once the fruit is either dispersed by animals or falls to the ground, seeds may germinate, continuing the cycle. The plant enters dormancy in winter, with leaf fall and cessation of active growth, ensuring survival until the conditions become favorable again in spring.
PropogationPropogation time
Spring-Early Summer
The red currant 'Jonkheer van Tets' can be most effectively propagated through hardwood cuttings. This process is best carried out in late fall after the leaves have dropped, or in early winter. To propagate, you would take hardwood cuttings of about 6 to 8 inches (15 to 20 centimeters) in length from healthy, mature stems. Make a straight cut at the base just below a bud, and a slanted cut at the top just above a bud to encourage water runoff and differentiate the top from the bottom. The cuttings should be planted in moist, well-drained soil, ensuring at least two buds are below the surface with several above. Roots and shoots will begin to develop in the spring.
