IMPORTANCE AND USES
➢Cut flowers
➢Garden display
➢Pot plants
➢Perfume and allied products like
•Rose water

PROPOGATION
a) Cutting
Scented roses are mainly propagated
through cuttings. Hard wood Cuttings in
case of polyanthas, climbers, ramblers
and soft or semi hardwood cuttings for
miniatures are used. Cuttings are
collected from healthier plants with 15-20
cm length and 3-4 nodes. Cuttings are
treated with IAA, BA 100ppm. Cuttings
are planted in mist chamber for easy and
quicker rooting.
➢PLANTING DISTANCE
Normally roses are planted at 60 x 60 cm spacing.
Protected cultivation: 60x30 cm, 30x20 cm, 30x30 cm
Outdoor cultivation: 75x75 cm for Hybrids, 60x60 cm for other varieties.
➢THERE ARE TWO TYPES OF PLANTING SYSTEMS
•Pit system: 45 cm3 (Length x Breadth x Depth)
•Trench system:
60 -75 cm wide
30-45 cm height
Any length depending upon availability.
60-90 cm pathway

PLANT GROWTH
REGULATORS
➢GA 3 @ 250 ppm sprayed during the
flushing if found very effective to,
•Increase the length of the stem/shoot o
Increases the no. of shoots/plant o
Induces early flowering o Prolongs the
flowering period o Enhance the flower
yield
➢CCC @ 3% results in more no. of buds
and also,
•Increase the flowering and size o
Increase the yield.
WEEDING
•Manual weeding is effective.
•Hoeing and roguing is also effective.
•Chemical control is economical, convenient and
effective.
•Diuron @ 2 kg ai/hac or Oxyfluorofen @0.5 kg ai/hac
•Effective control of broad leaved weeds by spraying
with 2,4-D, at the rate of 2 kg/600 l of water/hectare
25–30 days before flowering followed by cultivation of
soil to a depth of 6-10 cm.
MULCHING
•It conserve soil moisture.
•Supply humus.
•Suppress weeds.
•It is done with paddy straw, dried leaves.
•Also promotes growth and flowering.
•It promotes physical properties of the soil.
•Mulching 2 to 4 inches of organic material like wood chips if
found to reduce annual weeds and make hand weeding easier
PRUNING
•Pruning refers to the removal of certain portion of the plant.
•To improve the floriferousness and quality of flowers along
with vigour of roses
➢STEPS
•Remove dead, diseased or damaged wood.
•Remove branches that grow towards the centre of the plant
•Remove the weakest crossed branch and sucker growth
(growth coming from below the bud union)
•Shape the plant
•Make a cut at 45 degree angle ¼ inch above an outward
facing bud.
TYPES OF PRUNING
➢There are three types of pruning
practiced in rose
•Light pruning: Cut either at the 2nd
or 3rd eye bud immediately below
the flower bearing stalk.
•Moderate pruning: Healthy shoots
are pruned back to 45-60cm from
the base
•Hard pruning: Pruning is done by
leaving 10-30cm from the bud joint.
