Tuberose flower is one of the most important bulbous ornamental of tropical and subtropical areas. They are commercially cultivated for cut and loose flower trade, and also for the extraction of its highly valued natural flower oil. The serene beauty of the flower spikes, bright snow white flowers, sweetness of blooms, and delicacy of fragrance of this ornamental crop, transform the entire area into a nectarine and joyous one.

Tuberose: Climate and Soil

Tuberose flower can be grown with success under wide environmental conditions ranging from tropical to sub-tropical and temperature climate. If it is grown only for flower production, the climate must be warm and humid. Profuse flowering can be obtained throughout the whole year in a mild climate, free from extreme high and low temperature.

Tuberose: Temperature

Soil temperatures should be between 20 and 30°C for maximum bulb production. Flower spike formation, the mean minimum temperature is 13.4°C and for flower formation 18.3°C in Japan. Commercial cultivation of tuberose plants is mainly confined to warm, humid areas with average temperature range from 20 to 35°C. High atmospheric humidity and temperature around 30°C is optimum for Tuberose production.

Tuberose: Light

High light intensity is required for bulb and flower production. For bulb production, tuberose must be grown in full sun. Although this plant is insensitive to photoperiod, it has been reported that exposure to a day length of approximately 16 hours promoted the vegetative growth of plant enhanced the emergency of first flower spike by ten days.

Tuberose: Soil

Tuberose can be grown in any type of soil from light sandy loam to clay loam. A light, sandy and well drained soil makes lifting of bulbs easy. At least a 45 cm. deep, well drained, friable soil rich in organic matter and nutrients with plenty of moisture is preferable. Soil with high amount of clay or silt should be amended by incorporation organic matter and compost. Most of the nutrients become available to the plants in the pH range of 6.5 to 7.5 worth good aeration.

Gladiolus is one of the most important bulbous ornamental flowers that are becoming one of the most important cut flower. Ti is commercially cultivated for cut flower trade. The remarkable beauty of the flower spikes, bright snow white, red, pink and orange color bloom have attracted a large number of flower lovers.

Gladiolus: Climate and Soil

Gladiolus can be grown with success under wide environmental conditions ranging from subtropical to warm temperate. A warm and humid climate is considered to be good for this crop. Profuse flowering can be obtained throughout the whole year in a mild climate, free from extreme high and low temperature.

Gladiolus: Temperature

Soil temperatures should be between 15 and 25°C for maximum bulb production. Flower spike formation, the optimum temperature is 15°C to 22°C. Commercial cultivation of Galdiolus is mainly confined to warm, humid areas with average temperature range from 15 to 25°C.

Gladiolus: Light

High light intensity is required for bulb and flower production. For bulb production, Gladiolus plants must be grown in full sun. Exposure to a day length of approximately 14-16 hours promotes the vegetative growth of plant and enhances the emergence of flower spike.

Gladiolus: Soil

Gladiolus can be grown in any type of soil from light sandy loam to clay loam. A loamy soil with at least a 45 cm. deep, well drained, friable rich in organic matter and nutrients with plenty of moisture is preferable. Soil with high amount of clay or silt should be amended by incorporation organic matter and compost.

Gladiolus: Site

Gladiolus, unlike tuberose, is not very sun loving plant. For good vegetative growth and maximum yield of flowers, a site should be chosen where plants receive moderate sun throughout its growing period. The soil must have a good water holding capacity. A site protected from strong winds, hot and cold waves is preferable, so that there is no damage caused to the flower stalks.
