Well-drained sandy loam with pH of 6-7 is suitable.Bright sunshine for minimum of 6 hours is essential for the cultivation of roses. Day temperature of 260 C and night temperature of 150 C are ideal. It can be grown in the plains of Tamil Nadu where the optimum climate is available. It can be well grown in the plains of Tamil Nadu.
Propagation and planting
Cuttings with 2-3 buds are dipped in IBA or IAA @ 500 ppm. Pits of 45 cm x 45 cm x 45 cm are dug at 2.0 x 1.0 m spacing and 10 kg FYM is added to each pit before planting.
Irrigation
Irrigation is done once in 2 days until plants establish and once a week thereafter. Avoid salt water for irrigation purpose.
Manuring
After pruning in October and again in July the plants are manured with FYM 10 kg and 6:12:12 g of NPK per plant.
Micronutrients
Foliar application of 0.2% micronutrient mixture containing 20 g MnSO4 + 15 g MgSO4 + 10 g FeSO4 + 5 g B (2g of the mixture is dissolved in one litre of water) can produce bright coloured flowers.
Biofertilizers
Soil application of 2 kg each of Azospirillum and Phosphobacteria per ha at the time of planting. It is to be mixed with 100kg of FYM and applied in pits.
Aftercultivation
Pruning
The best time of pruning is the period when the activity of rose plant is least and the plant is dormant to near dormant stage. Pruning time will depend on climatic conditions of the particular region. The vigorous past season shoots are cut back to half the length. All the weak, diseased, criss-crossing and unproductive shoots are removed. The cut ends should be protected with Bordeaux or Fytolan paste + Carbaryl 50 WP.
Cut back the vigorous past season shoots to half the length during October to December. All the weak, diseased, criss-crossing and unproductive shoots are removed. The cut ends should be protected with Bordeaux paste or Copper Oxychloride + Carbaryl 50 WP.
Growth regulators
Spray 250ppm of GA3 (30 days after pruning) during early vegetative stage to increase the flower production.
