Rugosa Rose Rosa 'Roseraie de l'Hay' (Ru)

Water

Rugosa roses like 'Roseraie de l'Hay' should be watered deeply and infrequently to encourage strong root systems. Aim to provide about 1-2 gallons of water per plant each week during the growing season, depending on climate conditions. In hot, dry spells, you might need to water twice a week, whereas in cooler, wetter conditions, watering once a week or even less frequently may suffice. Always check the soil moisture; it should be moist but not waterlogged. During winter, reduce watering since the plant's water needs decrease significantly.

Light

Rugosa roses such as 'Roseraie de l'Hay' prefer full sun conditions, meaning they should receive at least 6 hours of direct sunlight each day. They thrive in a spot that is open and free from shade to ensure vigorous growth and abundant flowering. Partial shade can be tolerated, but it may reduce the number of blooms and weaken the plant over time.

Temperature

Rugosa roses, including 'Roseraie de l'Hay', are hardy and can tolerate a wide range of temperatures. They perform best when the temperature is between 60°F and 75°F but can withstand winter cold down to about -20°F. These roses are well adapted to grow in USDA hardiness zones 3 through 9, making them suitable for a variety of climates within these temperature ranges.

Pruning

Rugosa roses, such as 'Roseraie de l'Hay', should be pruned to maintain their shape and remove dead or damaged wood. Pruning is best done in late winter or early spring, just before the plant breaks dormancy. Thin out older canes to encourage new growth, and remove weak or crossing branches to improve air circulation. Rugosa roses can also be pruned after flowering to shape the shrub and control its size.

Cleaning

As needed

Soil

Rugosa Rose prefers well-drained, loamy soil enriched with organic matter, with a slightly acidic to neutral pH range of 5.6 to 7.0. A mix containing two-thirds garden soil and one-third compost or well-rotted manure would create an ideal growing medium for this plant.

Repotting

Rugosa Roses, being shrubs, are not commonly repotted as they are typically planted directly in the garden. Instead of repotting, they are occasionally transplanted if required, but care should be taken to minimize this as they do not like having their roots disturbed.

Humidity & Misting

Rugosa Roses, like many rosaceous plants, prefer outdoor conditions with average humidity. They are quite adaptable and do not require specific humidity levels indoors, as long as they are watered appropriately to compensate for dry air.

Suitable locations

• Indoor

  Ensure bright light, ample water, and room to grow.

• Outdoor

  Plant in full sun, enrich soil, water regularly, and prune.

• Hardiness zone

  3-8 USDA

Life cycle

The life cycle of Rosa 'Roseraie de l'Hay', commonly known as Rugosa Rose, begins with seed germination where the plant starts as a seedling emerging from stratified seeds that have undergone a cold treatment to break dormancy. The plant then enters a vegetative stage, developing a root system and foliage as it matures into a bush. Throughout the spring and summer, the Rugosa Rose progresses to the flowering stage, producing fragrant, deep pink to crimson flowers that are attractive to pollinators. Following pollination, the flowers develop into tomato-shaped, red to orange rose hips, which are seed-containing fruits marking the plant's reproductive stage. In autumn, as the weather cools, the plant prepares for dormancy by shedding its leaves and slowing growth; this allows it to conserve energy through the winter. In the subsequent spring, the Rugosa Rose resumes growth, thus repeating its life cycle.

Propogation

• Propogation time

  Spring-Early Summer

• Propogation: Rosa 'Roseraie de l'Hay', commonly known as Rugosa rose, is typically propagated by semi-hardwood cuttings. This process is most successful when undertaken during the plant's dormant period in late winter or early spring before new growth begins. To commence, select a healthy stem from the previous year's growth that contains several buds. Cut a piece of the stem about 6 to 8 inches (approximately 15 to 20 cm) in length, making sure the base of the cutting is made directly below a bud. Remove the leaves from the lower half of the cutting to prevent excess moisture loss and prepare a potting mix of half peat and half perlite or sand to ensure good drainage. Dip the base of the cutting in rooting hormone for increased chances of success and insert it into the potting mix. Keep the cutting in a bright, indirect light location and maintain consistent moisture levels without overwatering. Roots typically develop within 3 to 4 weeks, after which the new plant can eventually be transplanted outdoors.
