Cut Rose
Botanical Name – Rosa rubiginosa
Family-Rosaceae
- Red – First Red, Grand Gala, Red Corvette, Tajmahal.
- Yellow – Aalsmeer Gold, Gold Strike, Skyline.
- Pink – Noblesse, Flirt, Vivaldi.
- Orange – Movie Star, Miracle, Tropical Amazon.
- White – Ice Berg, Polo, Holly Wood, Avalanche, Tineke, Aloynica, Biyanka.
Soil –
- Fertile loamy soil with pH of 6 – 7.
- Roses are very adaptable and can be grown in almost any soil type given it is well drained, deep and full of humus (decayed organic matter).
Climate –
Protected cultivation:
- Day temperature of 25 to 28 C and night temperature not below
150C; relative humidity of 60-65%.
Open field cultivation:
- Moderately cooler places (like Hosur) and sub tropical climatic conditions (foot hills) are suitable.
Cut roses are commercially propagated by ‘T‘ budding on Briar rootstock.
Field preparation and Planting
- Prepare the soil by repeated ploughing.
- Roses can be planted on beds or ridges and furrows.
- One year old budded plants are planted.
- While planting, keep the budded portion 5 cm above the soil.
- Plant in such a manner that the budded branch is oriented towards the
centre of the bed.
Protected cultivation : 40 X 15 cm (7 plants/m2)
Open field cultivation : 60 x 60 cm (27,777 plants/ha) to 60 x 75 cm (22,222 plants/ha)
Soil is ploughed to fine tilth, flat beds are formed and suckers are planted at 45 x 45 cm spacing.
After pruning basins formed around the plant sand manures are applied 10-15 cm depth.
- 6:6:12 gm NPK/plant – Edward and Red rose
- 8:8:16 g NPK/plant – HT/Polyanthas/FB
Application in 3 stages
- 15 DAP
- After first flush of bloom
- After second flush of bloom
- Dose/plant – FYM 10 kg, Urea 65 g, Super phosphate 25 g, MOP 50 g
- Foliar feeding – micro-nutrients – 20 g MnSO4+ 15 g MgSO4+ 10 g FeSO4+ 5 g Boron @ 2g/l of water results in bright coloured flowers.
- Organic manures– oil cakes and bone meal are excellent sources of N and P respectively and may be applied after pruning.
1. GA 3 @ 250 ppm sprayed during the flushing if found very effective to,
- Increase the length of the stem/shoot
- Increases the no. of shoots/plant
- Induces early flowering
- Prolongs the flowering period
- Enhance the flower yield
2.CCC @ 3% results in more no. of buds and also,
- Increase the flowering and size
- Increase the yield.
Protected cultivation : Drip irrigation with fertigation
Open field cultivation : Irrigate once in 5 to 7 days depending upon the soil moisture.
1.Training –
- Early training is essential for plants under polyhouse conditions.
- Some of the first growth which consists of blind shoots must not be cut or bent, but left upright.
- Buds appearing at early stages are removed.
- The second growth will come to flower again in four to five weeks.
- By then, the plants will be 50 to 60 cm high, which is necessary to have enough growing speed in the plant and to have enough foliage for bending.
2.Bending
- The first bending (basal formation) is done on 35th day after planting.
- The main shoot is bent down so that lateral branches grow.
- The second bending is done after 2 years to strengthen the plants.
- 3. Shoot thinning
Periodically remove unproductive shoots and water suckers.
4. Pruning- Pruning is followed only under open conditions during the months of March and October.
- 5.Pinching
- Pinching is done to regulate flowering.
- Most of the commercial cultivars take about fiveand-a-half to six weeks from pinching to produce flowers during summer and about eight weeks during winter
Pest
1) Rose chafer beetle –
Symptoms of damage
- Adult beetles feed on the leaves and petals of flowers.
Management-
- Hand pick Cetonid beetles and destroy during the day time.
- Set up light traps to attract Holotrichia and Anomala spp.
- Spray Hostothion @ 2 ml/l.
2) Red scale – Lindingaspis rossi
Symptoms of damage
- Scales completely cover the stem.
- Affected portion of the plant dries up.
- In server infestation, the whole plant may die.
Management-
- Rub off the scales with cotton soaked in kerosene or diesel.
- Cut and burn the affected branches.
- Spray Malathion 50 EC @ 2 ml/l at the time of pruning and again during
March – April or apply Carbofuran 3G @ 5 g/plant or spray fish oil rosin soap @ 25 g/l.
3) Mealy bug
Management-
- Spray dimethoate @ 2 ml/l or profenophos @ 2 ml/l or fish oil rosin soap @ 25 g/l.
4) Flower caterpillar – Helicoverpa armigera
Symptoms of damage
- Young larva bores into bud and eats the internal content.
- Feed by thrusting the head inside the bud leaving the rest of its body outside.
- Flowers with perforated petals are seen.
Management-
- Spray Ha NPV 1.5 x 1012 PIB/ha or spinosad @ 0.75 ml/l.
- Hand picking of caterpillars.
- Spray chlorpyriphos 2ml/lit of water.
5) Bud worm
Management-
Spray thiochloprid 240 SC @ 2 ml/l or spinosad 45% @ 0.5 ml/l.
7)Thrips, aphids and leaf hoppers
Management-
- Spray acetamiprid @ 0.3 g/l or carbofuran 3G @ 5 g/plant.
- Spray neem oil @ 3 % or phosalone 35 EC @ 2 ml/l.
1.Black spot:
Management-
Spray carbendazim @ 1 g/l or azoxystrobin @ 1ml/l twice at fortnightly intervals.
2.Powdery mildew:
Management-
Spray carbendazim @1 g/l or wettable sulphur at 2 g/l or azoxystrobin@ 1 ml/l.
- Harvest the buds at tight bud stage with 60-90 cm long stems.
- Ensure that the foliage on the cut stem is healthy.
