Hybrid tea rose: Rosa Kordes' Perfecta

Bred in Germany and introduced in 1957, 'Kordes' Perfecta' performs best in dry climates, as rain can damage its petals. Its lovely fragrance is more apparent in warm climates than cold. When grown properly, its somewhat fickle nature rewards the grower with enormous, perfectly formed, glowing pink flowers. Like other hybrid teas, the most popular class of roses, it is a modern bush rose that grows into sturdy, upright plants with pointed blossoms, which are well suited for cutting. Most bloom continuously or in flushes throughout the growing season.

did you know?

During the Renaissance, fresh roses were prized beyond the summer months, so buds were packed in sand-filled clay pots and stored in cool streams until the flowers were needed.

general maintenance:

When leaf buds open in spring, remove winter-damaged branches, and crossing and weak canes; cut back remaining canes by a third to half. Deadhead unless decorative hips are desired; in north (Zones 7 and cooler), allow hips to develop in late summer and fall to prepare bushes for dormancy. In Deep South (Zones 8 and warmer), shorten canes again when growth resumes after summer.

pests/diseases:

Fungal diseases (black spot, powdery mildew) may stunt and discolor leaves or defoliate entire shrubs, especially in humid regions. Common pests include aphids, spider mites, and Japanese beetles.

controls:

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.

how to sow/plant:

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. In Zones 6 and warmer, set bud union just above soil level. In Zones 5 and colder, set bud union 2–4 inches below soil level. Cover roots with soil, and water thoroughly, but do not fertilize at this time.

water and fertilize:

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.

garden hint:

In the humid east, this rose is suited for Zones 5 to 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.
