Roses are one of the world's most popular flowers. Their beauty
and delicate fragrance have universal appeal. Roses are well adapted to
many different environmental conditions. They are useful for cut flowers
and many landscape effects. Since they are the product of centuries of
breeding and selection, many shapes, forms and colors provide endless
types to select from and use.
The many types of roses available offer selections for
almost any situation. Hybrid tea, floribunda and grandiflora are the most
commonly planted types. These require a rather vigorous pest control program
to maintain them in a vigorous, productive condition. Shrub and miniatures
and climbers require little or no pest control. Once they are established
they grow and flower for years with very little attention.

Types of Roses
|
|
Hybrid Teas:
Their solitary blooms are ideal for cutting, and
many are fragrant. The bushes are of medium to tall height. Hybrid
Teas are what most people think of when they see the word "rose".
Florist roses are usually Hybrid Teas, but they are grown in greenhouses
with strict training for long straight stems with only one bloom
at the top.
|
 |
|
Grandifloras:
Their large flowers are often borne in clusters,
but with stems long enough to make the individual flowers good for
cutting. Grandifloras are unusally taller in habit. A typical grandiflora
has the flower quality of the classic hybrid tea (long-stemmed,
high-centered bloom), but produced in clusters like a Floribunda.
Growth is normally tall and vigorous.

 |
|
Floribundas:
Free flowering, these plants produce masses of clustered
blooms or single flowers. Some of the longer-stemmed varieties are
good for cutting. They are good in mass plantings, tubs, or in mixed
plantings. Floribundas are easier to grow and demonstrate greater
disease resistance than the Hybrid Tea Roses while their cold hardiness
varies.

 |
|
Miniatures:
Very compact roses, they are ideal for containers,
borders or in window boxes. Dainty little rose plants are replicas
of their larger relatives. Flowers are small and plants range from
6 to 12 inches in height. Leaves and even thorns are perfect miniatures.
Plants are bushy and most are quite hardy. They are useful for low
edging and in rock gardens.

 |
|
Shrub Roses:
This is a diverse group with a full bushy habit.
Vigorous and hardy, they are the most trouble-free roses, and are
usually grown on their own roots. They were created by various breeders
who crossed older roses with various types of modern roses. Shrub
Roses are useful in the garden as relatively carefree and vigorous
specimens, blooming later than most other roses.
|
 |
|
Climbers:
Climbing roses can bloom on old or new wood, depending
on the variety, and many bloom repeatedly throughout the summer.
Their long canes appreciate a support such as a trellis, fence,
or wall.Climbing roses generally have larger flowers. While many
are fragrant and disease resistant, some have lost the sweet perfume
of the older varieties through hybridizing, and are more susceptible
to blackspot.
|
 |
|
Ground covers:
Arching, wide-growing roses suitable for growing
over banks and walls, providing dense blankets of color. These roses
have very pliable stems that make them suitable for use as groundcovers
because the stems normally lie close to the ground. They may be
trained upward, however.
|
 |
|
Old-fashioned Roses:
Lavish soft colors and intense fragrances.
|
 |
|
Tree Roses:
Roses grafted into a tree form, dramatic for patios,
walkways, or containers.

Rose Growing FAQ's
What type of light do roses require?
Roses grow best in full sunlight. If full sun is not possible,
locate them where they get a minimum of six hours of bright sunlight each
day. A location where they get only morning sun is to be preferred to
one where they get only afternoon sun. Morning sun helps dry leaves quickly
and reduces disease problems. Afternoon sun in midsummer fades and burns
petals.
Do I have to do anything special to the soil to prepare
it for my new roses?
Roses will not tolerate soggy soil. If well-drained areas
are not available, consider planting them in a raised bed or installing
subsurface tile drainage.
Roses prefer loamy soil with a high humus content. An ideal growing medium
includes 1/3 loamy soil, 1/3 peat moss, 1/3 composted cow manure and 1/2
cup bone meal or superphosphate.
What do I need to do to prepare my roses for winter?
Here in Zone 5 you will need to protect your roses from
the damaging effects of harsh winters. Most of all, remember that healthy
roses are stronger - fertilizing and watering regularly during the growing
season will make your plants better able to withstand harsh winters.
Here are some winter preparation tips:
Once you have had a few good frosts, leaves will start falling. Once the
plant has gone dormant, or after Thanksgiving, apply a dormant spray such
as lime sulfur and/or spray oil. This will kill pests and fungal diseases
that might try to overwinter on the plant or surrounding soil. It can
also help nudge those final leaves off. Rake leaves from around your plants
to prevent the spread of diseases.
For Hybrid Teas and Floribundas: Cover the crowns with a mound
of soil about 6" high, then cover the plants and mound with straw. Don't
prune your roses at this time, unless there is a concern that canes and
branches could be broken when loaded with snow.
Tree Roses: In Zone 5 where winter temperatures can dip below below
10°F., you must remove any stakes and gently dig away soil on one side.
Bend your tree rose downward to the ground and cover it with straw first,
then soil.
Climbing and Groundcover Roses: Cover the base of your climbers
with soil. Tie the canes and wrap them in burlap.
