As needed
  • water dropWater

    The White Rugosa Rose should be watered deeply once a week during its growing season, ensuring that the water penetrates to the roots. Aim to provide about 1 to 1.5 inches of water each time, which equates to approximately 0.62 to 0.93 gallons for a typical rose bush. During hot, dry spells, water twice a week, but reduce watering to every other week when weather is cool and damp. In winter or during periods of heavy rain, it may not be necessary to water at all. It's important to avoid overhead watering to prevent leaf diseases; instead, use a soaker hose or drip irrigation at the base of the plant.

  • sunLight

    The White Rugosa Rose thrives best in full sunlight, which means at least six to eight hours of direct sun per day. A spot that gets morning sunlight is ideal as it helps dry dew from the leaves and can reduce the risk of some fungal diseases. Partial shade can be tolerated, but too little light can impede blooming and lead to an unhealthy plant.

  • thermometerTemperature

    The White Rugosa Rose is hardy and can generally withstand temperatures as low as -20°F in winter and is comfortable in summer temperatures up to 90°F. However, the ideal growing temperature range for this plant is between 65°F and 75°F. Providing adequate water and mulch can help the plant endure temperature extremes.

  • scissorsPruning

    Prune the White Rugosa Rose in late winter or early spring before new growth starts, to shape the plant, remove dead or diseased wood, and encourage healthy growth and blooming. Prune out weak or crossing branches to allow for good air circulation. Deadheading, or removing spent flowers, will encourage reblooming through the season.

  • circleLife cycle

    The Rosa 'Blanche Double de Coubert' (Ru), commonly known as the Hybrid Rugosa Rose, starts its life cycle when a seed germinates in the soil, given adequate moisture and temperature conditions. Upon sprouting, the seedling begins to develop roots and shoots, entering into the vegetative growth stage, where it forms a strong bushy structure with pinnate leaves. During the flowering stage, typically in late spring to early summer, it produces fragrant, white double flowers which are pollinated by insects or other natural means. Following pollination, the plant forms rose hips (fruit) that contain seeds, completing its reproductive cycle. In the autumn, this deciduous shrub enters a dormancy phase where it sheds leaves to conserve energy through the winter. The plant can live for many years, repeating this cycle seasonally, and can propagate through cuttings or layering in addition to seed production.

    • Propogation time

      Spring-Early Summer

    • Propogation: The most popular method of propagating the White Rugosa Rose, scientifically known as Rosa 'Blanche Double de Coubert' (Ru), is through softwood cuttings. This technique commonly takes place in late spring or early summer when the new growth is still tender and green. To propagate, a gardener selects healthy, non-flowering shoots and snips off a 6 inch (approximately 15 cm) length. The cut is made just below a leaf node, and the lower leaves are removed. The basal end of the cutting may be dipped in rooting hormone to stimulate root development and then it is placed in a pot filled with a mix of peat and perlite. The cutting should be kept moist and in a warm, bright place out of direct sunlight until roots have formed, which typically takes several weeks. It is also crucial to maintain adequate humidity by covering the pot with a plastic bag or placing it in a propagator.
