Pruning in rose

• time of pruning in terai is done at first fortnight of October.
• At the time of pruning, the cut given to the branch should be slanting cut opposite to the bud. So, rotting of bud may not take place by rain.
• While pruning, all the intercrossed, in laced, week and diseased branches should be removed.
• In HT rose and Floribundas, amount of pruning is done according to the age of the plant.

1. Light pruning (<4 year): each bush will have 6-8 canes & each cane will have 6-8 buds.
2. Moderate pruning (4-8 years): each bush will have 4-6 canes & 4-6 buds/ cane.
3. Heavy pruning (> 8 year): also called hard pruning: each bush will have 2-4 canes & each cane will have 2-4 buds.

• After pruning, cut should be covered with fungicidal paint to check the infection of Dieback pathogen (Diplodia rosarum).
• Fungicidal paint can be prepared by mixing Linseed oil (heat and cool), lime and CuSO4 at the ratio of 3:2:1. (CuSO4 should be fried).

Root exposing in rose:

• Root exposing is also done at the time of pruning which makes the bigger size of flower and less infestation of diseases and insect.
• Root exposing is done during pruning for 15 days.
• After 15 days, 5 kg FYM and 50 gm rose mix (5:8:18 NPK)/bush is added, filled back then irrigate the plant.
• After 35-40 days, flowering will start. This practice increases the flower size of the rose due to the physiological stress to the plant. It increases the C/N ratio and it also makes the plant healthy.

Harvesting stage and time

• Red and Pink Roses are harvested at a stage when first two petals are beginning to unfold and calyx is in downward position.
• Similarly, in yellow cvs. – Slightly later than red and pink rose and in white cvs- slightly later than red and pink.
• For distant market supply, roses should be harvested at tight bud stage.
• Harvesting should be done during cool hours of the day in evening.
• Evening is the best times for harvesting cut roses. Immediately after the cut, put the flower in the water containing bucket.
