Old garden rose: Rosa Boule de Neige

Old garden rose: Rosa 'Boule de Neige' was bred in France and introduced in 1867. Its crimson buds open into very double, pure-white rosettes. Like other Bourbons, a class of old garden roses, it can achieve great stature in the garden, reaching 5 to 6 feet in height and spread. Bourbons' wide-ranging habit makes them suitable for growing up pillars or training on walls, and they produce fragrant blooms in spring and again in fall.

Martha uses lamb’s ears lavender catmint and erect plants, such as foxgloves hollyhocks delphinium, and monkshood which contrast well with the mounding forms of many old garden roses and come in similar colors. Monitor soil moisture all season; use soaker hose to give roses an inch of water weekly during dry weather. Once newly planted bare-root roses break dormancy, feed with an all-purpose fertilizer at half rate, following package directions. After the first season, feed with balanced organic fertilizer in early spring and again in early summer at first bloom, and spray bushes with kelp extract in early fall. 0 To discourage fungal diseases, avoid wetting foliage, and remove and dispose of fallen leaves. Spray a mixture of 4 teaspoons baking soda and 1 tablespoon horticultural oil per gallon of water; repeat weekly. In Zone 10, strip remaining leaves from shrubs at spring pruning. For aphids and spider mites, use horticultural oil, following package directions. Handpick Japanese beetles, and destroy. CRL;, DK;, Rose Bible;, Taylors;, Arena; very strong, sweet, pervasive In the humid east, this rose is suited for Zones 6?9. To extend the hardiness range a zone or more northward, protect through winter by mounding a mix of 1 part sandy loam and 1 part compost 10 inches high around and over the bases of the bushes. Apply the mix in late fall when cold weather has settled in. Remove half of mix in spring when roses' buds swell, and rake the rest out for mulch. The original Bourbon rose traced its lineage to the reign of Louis-Philippe (1830?1848), when residents of Ile de Bourbon, now called Réunion Island, planted mixed hedges of China and damask roses that naturally cross-pollinated. The resulting hips were sent to the king's gardener in France, and the Bourbon class of roses was born. Choose a sunny site with fertile, well-drained soil, and amend with well-rotted manure or compost. Plant container-grown roses in spring or fall (at least a month before frost) at the same level they were in the pot. Plant bare-root roses in early spring; before planting, soak entire plant in water for 12?24 hours to replace lost moisture. Dig a 2-by-2-foot hole. Return some soil to hole, forming a 1-foot mound. Place plant on the mound, fanning out roots.Set bud union just above soil level. Cover roots with soil, and water thoroughly, but do not fertilize at this time. 1 When leaf buds open in spring, remove winter-damaged branches, and crossing and weak canes. After early-summer flowering, cut back remaining canes by a third to half. Deadhead after spring flowering, but in north (Zones 6?7), allow hips to develop in late summer and fall to prepare bush for dormancy. fertile, well drained 0 1 0 0 0 0 0 0 0 0 0 0 0 0 1 0 0 0 1 1 0 0 0 0 0 0 1 0 0 0 0 1 1 0 0 > 0 0 0 0 Bourbon rose
