Knock Out Roses
Knock Out Roses

The Knock Out family of roses are easy to grow and do not require special care. They are the most disease resistant rose on the market with stunning flower power. Fragrant and a great punch of color!

+ More About Knock Out Roses

Enjoy their generous bloom cycle (about every 5-6 weeks) until frost. No need to deadhead, they are self cleaning and winter hardy to USDA Zone 5 and very heat tolerant. If unpruned, the Knock Out will easily grow to be more than 3-4' tall. Once a year it is recommended to cut to about 12" above the ground in early spring (after the last hard frost) for maximum performance.

Shrub/Ground Cover Roses

Also known as the Drift or Carpet Rose, these beauties prefer hot conditions and will also continue to bloom. Being disease resistant they are pretty easy to maintain and carry gorgeous clusters of flowers.

+ More About Shrub Roses

An ideal rose for both home gardeners and professional landscapers. They do not require spraying and are resistant to blights such as black spot and mildew. Plant height can vary between 1 - 5' or more. Shrub roses are very fragrant, attract birds and make great cut flowers. The cluster of blooms are accented by brilliant golden yellow stamens that sit over deep glossy dark green foliage with a burgundy edge.

Hybrid Tea Roses

The most popular variety of rose. Hybrid Teas are characterized by their large, high centered buds, classically formed blooms, and stiffly upright habitat. Long favored in a smaller garden in a formal setting.

+ More about Hybrid Tea Roses

The exquisitely shaped flowers continue to be the standard rose of the floral industry, due to the fact they're generally borne singly on long, strong stems. They offer a captivating fragrance and can grow to 5' tall and wide. A true beauty in a bouquet, but equally rewarding adorning your garden.

Climbing Roses

+ More About Climbing Roses

Rose Care

Some people shy away from roses thinking they're too hard to care for or may be too delicate! With the right care, anyone can grow beautiful healthy roses. Here are some helpful hints from our local experts to get you started!

+ More About Planting Roses

Container-grown roses can be planted all season. Begin by digging a hole large enough to accommodate the roots of the plant. In Iowa, the bud union of hybrid tea, grandiflora, and floribunda roses should be planted two to four inches below the soil surface to prevent the top from dying of harsh winter weather. The bud union is denoted by a knob or crook in the stem. Carefully remove the rose from the pot without disturbing the soil ball. Place the rose in the pre-dug hole. Fill the hole with soil, and water thoroughly.

+ More About Proper Watering

Roses will require watering during hot, dry weather. The actual amount and frequency depends upon weather conditions and soil type. In most garden situations, a deep soaking about every two weeks should be sufficient. The soil should be soaked to a depth of 10 to 12 inches. Apply the water directly to the soil. Over-head watering wets the foliage and may increase disease problems. If overhead watering is unavoidable, the best time to water is during the morning. This allows the foliage to dry quickly. Mulch around the roses will help to conserve soil moisture and also help to control weeds. Possible mulches include wood chips, shredded bark, pine needles, and cocoa bean hulls. Spread 2 to 4 inches of mulch around the base of each plant or over the entire bed.

+ More About Fertilizing Your Roses

To encourage healthy, vigorous growth and abundant bloom, roses should be fertilized three times a year. The first application should be in early spring immediately after pruning. The second application should be made during the first bloom period. The third application should be made in mid to late July. Do not fertilize after July 31. Later fertilization may produce succulent new growth, which may not harden sufficiently before winter. Dr. Earth Rose and Flower Organic Fertilizer 5-7-2 or Miracle-Gro Rose Food 18-24-16 will produce lush foliage and more abundant blooms. Thoroughly water the roses after fertilization.

+ More About Controlling Insects & Diseases

Continue a rigorous spray program through the summer months to control insect and disease pests. Combination sprays, such as Bayer Advanced All-In-One Rose and Flower Care, which includes fertilizer, insecticide, and fungicide, are available at Culver's Garden Center. Disease problems are most severe during periods of rainy weather. The key to disease control is prevention. Begin applying fungicides before symptoms appear and reapply as directed on the label. Spray both the upper and lower leaf surfaces to prevent disease infection.

+ More About Deadheading

It is necessary to remove spent flowers to conserve the plant's energy and encourage repeat blooms for certain varieties or roses. The procedure for deadheading roses during the first growing season differs from established roses. On a recently planted rose, it is usually recommended that the faded flower be removed above the uppermost 3-leaflet leaf. Removal of a large amount of foliage reduces the food manufacturing capacity and may weaken the young plant. When deadheading established roses, the stem may be cut back to a 5-leaflet leaf. Retain at least two 5-leaflet leaves on each shoot. Use sharp tools (hand shears or knife) to remove faded flowers. Cut about 1/4 inch above an outward facing bud and leaflet with the cut made parallel to the angle of the leaflet.

+ More About Winter Protection

To prevent their possible dieback or death, hybrid tea, grandiflora, and floribunda roses should be protected in the fall. Stop deadheading roses in late summer. This allows the development of rose hips, which promotes hardening of plants for the winter months. Rose plants usually become dormant in late October to early November in northern Iowa and mid-November in central and southern areas of the state. Once dormant, tie the rose canes together with twine to prevent strong winds from whipping and possibly damaging the canes. Any existing mulch should be removed from the rose bed and approximately one foot of soil mounded over the base of each plant. Place one to two feet of mulch over the mound of soil.
