If properly planned, growth regulator can bring in very quick, rapid and distinctive changes in the target plants, and show appreciable improvement with high commercial and aesthetic value; which no other technology can offer in such a short span of time. However, there is need of continuous search for new growth regulators and cost effective technology for modifying the effect of unfavourable environmental conditions, increasing the resistance against pests and diseases, manipulating flowering and improving the post harvest life' and quality of cut flower of roses, without neglecting the environmental safety. Very little is known about the regulation of expression of genes involved in petal senescence. (...)

Allowing free flow of air and sunlight in all parts of the rose bush, and the ideal bush is one, which is open in centre with branches growing upwards and outwards to help in improving productivity. Encouraging new shoots from the eyes near the base of the plants for adding vigour to the plants and producing good flowers.

(...)

Rose plants need special mineral nutrients (10/19/2010)
(...) It is an essential component of the proteins and related amino acids, which are critical not only as building blocks for plant tissue but in the cell nuclei and protoplasm in which hereditary control is vested. It is essential for carbohydrate utilization within plants and stimulates root growth and development as well as uptake of other nutrients. Nitrate and ammonium form of nitrogen are the major sources of inorganic nitrogen taken up by the roots of plants. (...)

Plenty of water is necessary for growing beautiful roses (10/19/2010)
(...) rose bush might loose through transpiration about 30 gallons of water during the growing period. A well-established Rambler "Dorthy Parkins" may transpire about 100 gallons of water. Misting in the greenhouse is beneficial for faster growth of rose plants. (...)

Growing roses in pots is possible for many types of roses (10/19/2010)
(...) There is no denying of the fact that pot roses have advantages and potential which offer great scope for creativity and enjoyment. The pots should be large enough to allow growing room and to ensure adequate water holding capacity.

(...) Blue granite produces very good soils. White granite, limestone and red iron stone usually make poor soil, and these can be improved by addition of humus in sufficient quantities. Shale soils, alluvial soils, and yellow limestone soils are generally good. (...)

Importance of right temperature and humidity for roses (10/14/2010)
(...) In high Tropics and North-East India the season is for 8 months from October to May, and in subtropical climate, roses can be obtained from November to April. Shoots growing in short branches at 21°C and a photoperiod of 8 hours under florescent light aborted almost all of their flower buds. Low incidence of abortion occurred in shoots growing on long branches. (...)

Selection of land for commercial rose growing (10/14/2010)
(...) Also in sandy soils, organic matter improves the water holding capacity as well as the nutrient holding capacity. The initial preparation of rose beds should preferably be done during summer season, so as to expose the soil in sun and air for a longer time, and during monsoon it settle down before planting. Soil should be well pulverised; stones, brick pieces, gravel and other foreign material removed. (...)
