Silver Jubilee Rose Rosa 'Silver Jubilee' (HT)

Water

The Hybrid Tea Rose 'Silver Jubilee' should be watered deeply but not too frequently, allowing the soil to dry out slightly between watering. Generally, watering once a week with about 1 inch of water (0.6 gallons) is sufficient, but this may vary depending on climate and soil conditions. During hot and dry spells, you may need to water twice a week. It is best to water early in the morning directly at the base of the plant to avoid wetting the foliage, which can lead to fungal diseases.

Light

Hybrid Tea Rose 'Silver Jubilee' thrives best in full sunlight, requiring at least 6 hours of direct sun daily. It should be planted in a spot that receives morning sunlight and is well-aerated to promote healthy growth. Avoid placing it where it will get only afternoon sun, as this can be too intense and may cause the blooms to fade quickly.

Temperature

Hybrid Tea Rose 'Silver Jubilee' performs well in a range of temperatures but prefers a temperate climate. It can tolerate minimum winter temperatures down to about 20°F, but prolonged exposure below this can be damaging. The ideal growing conditions are between 60°F and 70°F. Roses are dormant in colder months, so they can withstand lower temperatures, but during the growing season, extreme heat above 90°F can stress the plant.

Pruning

The Hybrid Tea Rose 'Silver Jubilee' should be pruned to maintain shape, remove dead wood, and encourage vigorous growth and bloom production. Pruning is best done in early spring, after the last frost when buds begin to swell. Cut back about one-third of the plant's height, remove any dead or diseased branches, and open up the center for better air circulation. Repeat bloomers should also be deadheaded regularly to encourage more flowers.

Cleaning

As needed

Soil

Hybrid Tea Roses like Rosa 'Silver Jubilee' thrive in well-draining, rich soil with a pH between 6.0 and 7.0. A good soil mix consists of equal parts loam, peat or compost, and perlite or coarse sand to ensure adequate drainage.

Repotting

Hybrid Tea Roses are typically not repotted as they are outdoor plants. If grown in containers, they should be repotted every 2 to 3 years in the spring.

Humidity & Misting

Hybrid Tea Roses, such as the 'Silver Jubilee', prefer outdoor environments where humidity is naturally occurring, and they are not highly dependent on strict humidity levels.

Suitable locations

• Indoor

  Ensure full sun, good airflow, and regular watering.

• Outdoor

  Plant in full sun with well-draining soil and space for air.

• Hardiness zone

  6-9 USDA

Life cycle

The life cycle of the Rose 'Silver Jubilee' (Hybrid Tea) begins with seed germination or, most commonly, with the rooting of cuttings, as hybrid teas are typically propagated for consistency. After establishment, the plant enters a vigorous vegetative growth phase where leaves, stems, and thorns develop. The next stage is the flowering phase, which occurs repeatedly throughout the growing season, characterized by the development of buds that bloom into the plant's distinctive large, fragrant flowers. Post bloom, the roses may form hips (seed pods) if pollination occurs, but many gardeners deadhead spent blooms to encourage further flowering. In the autumn, the plant begins to go dormant, preparing for the winter by slowing its growth and eventually shedding leaves in regions with a cold winter. Finally, after winter dormancy, the cycle recommences in the spring with the plant breaking dormancy and resuming active growth, leading to new vegetative growth and flowering.

Propogation

• Propogation time

  Late winter - early spring

• The Rosa 'Silver Jubilee' (Hybrid Tea Rose) is most commonly propagated through the method of softwood cuttings. This technique is often carried out in late spring or early summer when the plant’s new growth is still flexible but mature enough. A cutting, generally about 6 to 8 inches long, is snipped from the healthy, non-flowering stems of the rosebush. The leaves at the lower end of the cutting are removed, and the bottom of the cutting is dipped in a rooting hormone to enhance root development. It's then planted in a well-draining soil mix and kept under high humidity conditions, often with the aid of a plastic cover to retain moisture. The cuttings need to be kept in a shaded or indirect light location until roots have developed, which typically takes several weeks. Careful monitoring for moisture levels and signs of growth is essential during this period.
