Jacques Cartier Rose Rosa 'Marchesa Boccella' (DPo)

Water

Jacques Cartier roses require regular watering to maintain moist soil, especially during their active growth in the spring and summer. Ensure the soil around the roses is moist but not waterlogged, providing deep watering once or twice a week, depending on the weather conditions. Each watering session should consist of about 1 to 2 gallons of water, allowing it to penetrate deeply into the soil to encourage strong root development. Adjust the amount of water during the hotter, drier months, and reduce the frequency of watering during the winter when the plant is dormant.

Light

Jacques Cartier roses thrive in full sunlight, receiving at least 6 to 8 hours of direct sunshine daily. The best spot for planting these roses is an area where they are exposed to morning sunlight to help dry dew from the leaves, reducing the risk of disease. The intense afternoon sun can be tolerated, but in regions with extremely hot climates, some light afternoon shade may be beneficial.

Temperature

Jacques Cartier roses are hardy and can withstand a range of temperatures; however, they grow best in temperatures between 65 and 75 degrees Fahrenheit. They can survive minimum temperatures down to about 20 degrees Fahrenheit during dormancy. To ensure optimal growth and flowering, avoid placing these roses where they can be exposed to temperatures above 90 degrees Fahrenheit for prolonged periods.

Pruning

Pruning Jacques Cartier roses promotes healthy growth and rejuvenates the plant for better flowering. Prune in early spring as new buds begin to swell, removing any dead or diseased wood and thinning out the center to improve air circulation. Cut back the remaining canes by about one third to one-half to encourage new growth. Additionally, deadhead spent flowers throughout the blooming season to encourage repeat blooming.

Cleaning

As needed

Soil

Jacques Cartier Rose, or Marchesa Boccella, thrives in well-draining loamy soil enriched with organic matter such as compost or well-rotted manure. The best soil pH for this plant is slightly acidic to neutral, from 6.0 to 7.0. A mix of two parts loam, one part peat moss, and one part perlite or sand ensures good drainage and aeration.

Repotting

Jacques Cartier Rose usually does not need frequent repotting as it is commonly grown outdoors. In a garden setting, instead of repotting, annually replenishing the top layer of soil with compost or organic matter can maintain soil health. If grown in a very large container, repotting might be necessary every 2-3 years.

Humidity & Misting

Jacques Cartier Rose prefers outdoor conditions where humidity is natural and not excessively high. Average ambient humidity is generally sufficient, while ensuring good air circulation around the plant to prevent diseases such as mildew.

Suitable locations

• Indoor

  Ensure bright light, ample airflow, mild humidity.

• Outdoor

  Plant in full sun, well-draining soil, water regularly.

• Hardiness zone

  4-9 USDA

Life cycle

Rosa 'Marchesa Bocella', commonly known as Jacqueminot Rose, starts its life cycle from a seed or more commonly from a grafted cutting. As it germinates or takes root, it enters the vegetative stage, where foliage growth and root development are primary focuses. When environmental conditions are right, typically in spring, it begins the growth of stems and leaves in preparation for flowering. The plant then enters the blooming stage, where the characteristic fragrant pink flowers develop and blossom, attracting pollinators. After pollination, the flowers produce hips, which contain seeds for reproduction. As the growing season ends, the Jacqueminot Rose enters a period of dormancy, particularly in colder climates, where it conserves energy for the next cycle of growth.

Propogation

• Propogation time

  Spring-early summer

• The Rosa 'Marchesa Bocella', also known as the Jacqueminot Rose, is commonly propagated by the method of softwood cuttings. This technique is carried out during the growing season, typically in late spring or early summer, when the plant's new growth is still flexible but not too tender. To propagate using softwood cuttings, a gardener would cut a 4 to 6-inch piece (approximately 10 to 15 cm) from the tip of a healthy, non-flowering stem, making the cut just below a leaf node. The lower leaves are removed, and the cut end is often dipped in rooting hormone to encourage root development. The cutting is then placed in a well-draining potting mix, ensuring the leaf nodes are buried where roots and eventually new shoots can emerge. The soil should be kept moist but not waterlogged, and the cutting should be placed in indirect light until roots have established, after which it can be gradually acclimated to more direct sunlight.
