The Guillot family nursery, Roseraie Guillot, which developed the Generosa shrub roses, has been in the business of rose hybridizing for more than 160 years. In 1867, the nursery introduced 'La France,' the first hybrid tea rose.

general maintenance:

In late winter, shorten canes by half. When leaf buds open in spring, remove dead and diseased branches and crossing and weak canes. Deadhead spent blooms to promote flowering. In areas where frost occurs, discontinue deadheading and fertilization in early fall to prepare for dormancy.

pests/diseases:

In humid regions, fungal diseases (black spot, powdery mildew) may stunt and discolor leaves or defoliate entire shrubs. 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:

Fertilizing roses late in the season (less than 6 weeks before first frost) actually decreases their winter hardiness -- belated feedings promote tender new growth and the production of new canes that won’t mature fully and harden off before winter’s onset.
