How to Care for a Banksiae Purezza Rose


Banksiae purezza is a white-blooming varietal of the famous hybrid thornless shrub roses also know as Lady Banks roses. Banksiae roses have a climbing or rambling growth habit that allows them to sprawl extravagantly over surfaces, increasing the plant's exposure to sun and resulting in vigorous bloom each year from spring through summer and into fall in some warmer climes. Like all roses, purezza benefits from a rich soil, ample water and regular feeding.

Step 1

Plant your banksiae shrub roses in a full sun exposure for optimal bloom. Some afternoon shade can be tolerated in warmer and drier climates. Morning shade is not desirable as the leaves remain wet with dew through the day and can lead to mildew and other disease. Provide a nutrient-rich, easy-draining planting soil that is amended or top dressed each year with compost and well-aged manure.

Step 2

Water your shrub rose to keep the soil at its base evenly moist but not soaking wet. Depending on your climate, size of the shrub and time of year, this may translate into daily to once-a-week watering. Monitor the soil carefully and do not allow it to dry out between waterings. Mulch around the base of the shrub out to the drip line with shredded bark or coca bean hulls to preserve moisture and keep weeds from settling.

Step 3

Feed your banksiae shrub roses with an organic fertilizer such as rose tone or fish emulsion in the spring, summer and fall according to the product-label dosing directions. Water in well at application. Alternatively, use a synthetic formula sold specifically for use on roses. Refrain from feeding in the late fall or winter to prevent new growth from cold or frost damage.

Step 4

Harvest your banksiae purezza roses at their peak of bloom for use in cut-flower arrangements. Use sharp clean secateurs to cut individual blooms or branch clusters where some flowers are in bloom and some remain in bud. Deadhead roses left on the plant to encourage new bloom. If you like decorative rose hips, allow some or all of the blooms to fade on the shrub and do not deadhead any of the flowers.

Step 5

Prune to control the shape, size and sprawl of the roses after bloom in the late summer or early fall. In colder climes, prune at least six weeks before the first hard frost. Remove up to 1/3 of the shrub mass but no more at each pruning to lessen shock to the plant. Place all cuts a 1/4 of an inch above a leaf node to encourage new branching.
