• The site chosen should be free from weeds, nematodes or soil-borne pathogens.
Planting• Roses require loamy, well drained soil. • They are planted in the circular pits about 60- 90
cm across and 60 -75 cm deep. • Remove all the broken and bruised leaves while
planting the plant. • Roses require atleast six hours of direct sunlight
for the growth. • The best time to plant the Rose plants rests
between September to October.
Cont…• The rose plant needs cutting from time to time. It
requires manures and fertilizers at the time of planting.
• Watering: Rose should be given one or two deep soaks per week to encourage deep rooting and drought resistance.
• Mulching is also done for protection against hot sun and to keep the weeds down. Example: Bark mulch, peat moss, well rotted compost etc…
Pruning• The best time to prune is in the early spring just
as you see the new growth beginning to bud. Pruning is done to:• Encourage new growth and bloom • Remove dead wood • Improve air circulation • Shape the plant
There are 3 methods of Pruning:
• Hard Pruning
• Moderate Pruning • Light Pruning
Classification of Roses
Roses are divided into three classes:
• Species Roses
• Old Garden Roses
• Modern Roses
Types of Roses
• Hybrid Tea Roses • Floribunda• Grandifloras• Modern Shrub Roses• Climbing Roses• Miniature Roses
Floribunda• Known for its large
clusters of medium sized blooms that cover the rose bush all season long.
• The plant is generally hardy and easy to grow and maintain.
• It usually grows to about 3 feet tall.
Grandifloras• They are similar to
hybrid teas.• It has a unique ability
to grow clusters of large hybrid tea-type flowers on strong straight stems.
• Plants are large and grow to about 6-9 feet tall.
Propagation
• Seeds• Cuttings• Layering• Grafting
Diseases
• Black Spot• Botrytis• Powdery Mildew• Rust• Rose Mosaic
Black Spot
• It is caused by the fungus Diplocarpon rosae.• The spots, which may be as much as 12mm
across, are generally circular and have an irregular edge often with a yellow halo.
• Spray of Thiophanatemethyl(0.1%) is effective for its control.
Powdery Mildew
• It is caused by the fungus Sphaerotheca pannosa.
• This disease can cause young leaves to curl and turn purple. Young canes may be distorted and dwarfed.
• It can be controlled by the lime- sulphur spray.
Pests
• Aphids
• Two Spotted Mite
• Thrips
• Root Knot Nematode
Aphids• Aphids are soft bodied
insects 1-2mm long. Often green but occasionally light-brown.
• They feed on the sap of the plant by piercing the plant cells via a proboscis.
Thrips• Thrips are slim-winged insects
1mm in length, resembling fine black slivers of wood.
• Flowers are often left looking bruised and lustreless.
World Leading Rose Exporters• The Netherlands, with about 8000 hectares of land
under Rose cultivation, is the global leader in Rose cultivation.
