Light hoeing is a very effective way to keep the soil porous so that light, air and water may reach the roots better to improve moisture retention capacity to keep the rose beds free from weeds. Roses are shallow rooted plants and the roots of established plants tend to go near the surface. Hence shallow hoeing is preferred as the deep cultivation destroys the rootlets. Hoeing should be done when soil is moist or dry but not too wet or soggy.
The removal of damaged and surplus new growth in the following weeks after pruning should be followed as a routine. Any suckers appearing from the stock should be removed promptly. In Hybrid Tea roses only one or at best two buds should be allowed to flower upon each shoot so as to have a large sized blooms. All other buds should be removed or disbudded. Sprays developed from basal shoots in Floribunda roses very often. The central bud which appears first, blooms much earlier than the other buds on the spray. To give the spray a balanced look with flowers, central bud may be removed.
It is generally practiced for the return crop and to adjust flowering for a particular season. An examination of rose stem will show that below a flower bud there is strapshaped leaf followed by 3 leaflets and 5 leaflets leaves in the axils of which there are pointed buds. At the bottom of these all other nodes have rounded buds. If the pinching is done above a pointed bud these will be forced to form a shoot which will bear a short stemmed flower.
To ensure a reasonable long stem, pinching has to be done on 5-leaflet leaf with a rounded bud. The shoot selected for later flower production (return crop), are pinched by removing 3-5 cm of terminal growth, after at least 15 cm growth is formed. These shoots may again be pinched after 4 to 6 weeks. This procedure of pinching prevents flowering and encourages the plant to form new growth at the base.
In the Hybrid Tea roses, by which young vegetative shoots developing from the axils of the leaves of the basal shoots and lateral shoots are removed to allow each shoot to develop with only one terminal shoot. The side shoots which developed from the eyes down the stem below the terminal flower bud are also to be pinched off right at the initial stage to get a single bloom of quality and size. All but one of the laterals may be pinched off and the main stem cut back just above the one that has been allowed to remain while removing the terminal flower.
To keep the rose garden attractive faded flowers and spent blooms are to be removed as a daily routine. For obtaining good quality flowers in Hybrid Tea roses removal of faded or spent blooms may be performed by cutting two to three leaves'below the footstalk of the flower. This may induce development of two or three laterals. Generally top most laterals are not a strong one, while the next laterals are stronger. In such case, the top most lateral along with the stem should be cut away, just above the next laterals which are kept for flowering. While in other types of roses, only the faded blooms may be cut back.
After pruning occasionally some blind· shoot appear in rose plants. These are the shoots in which growing point of the shoot terminates without producing flower buds. These shoots draw excess quantity of water and nutrients, and hence, the productive parts of the plant suffer. Blind shoots may appear due to severe pruning, shading of young shoots and content of low auxin or gibberellins level in the shoot.
