Read More... Cultivation and Propagation: Dracaena angustifoliaSN|30145]]SN|30145]]is comes under the category of Tropical Shrubs and is perfect for growing indoors. Average water needs, but don't over-water and suitable for growing in Pots. Suitable for both Home and Office, also cultivated as an ornamental shrub for parks and gardens. It will grow in warm subtropical or tropical climates and appears to be easy-to-grow and rewarding. It has average water needs, but don't over-water.
Soils: Need very drained soils and is suitable for growing in Pots. Give the plant an airy growing medium consists of both non organic material such us clay, pumice, lava grit, and peat or leaf-mould. It like quite small pots, repott in very later winter, early spring.
Fertilizing: Ferilizers can be used in light amounts. Apply general garden fertilizer (10-30-10) including all micro nutrients and trace elements or slow release fertilizer to the planting bed at 3-month intervals during growing season, and to container plants at bimonthly intervals.
Exposure: Requires sunny or half-shaded locations.
Water Requirements: Water regularly during the active growing season from March to September, but do not overwater this plant. No water should ever be allowed to stand around the roots. Keep almost dry in winter.
Hardiness: This plant has tolerated temperatures down to –0ºC. However it can be difficult to get it to look its best without a good amount of heat and sun and so it is only really suited to the tropics (USDA Zones 10-11). Keep the plant cooler in winter, but maintain the light as bright as you can so that any growth which it may produce at this time will not be etiolated. It can be grown outdoors in the summer months to benefit from direct exposure to light, and especially exposure to high summer temperatures.
Wind tolerance: Has a limited wind tolerance it is knock over by very strong winds, the plants may smash to to the ground... best to plant in such a location where winds are not a big issue.
Pruning: None necessary, except to remove dead lower leaves and spent fruit stems (panicles). Drastic pruning usually not needed.
Medicinal properties: Each part of the neem tree has some medicinal property. Antispasmodic, anti-proliferation activity, leaves boiled and the juice drunk for asthma; leaves poultice applied on swelling of joint; leaves decoction given to patients with poor appetite. Roots juice given in jaundice; a decoction of roots of Dracaena angustifoliaSN|30145]]SN|30145]] with bark of Mangifera indica and Syzygium cumini given as a postpartum remedy.
Traditional uses: Ceremonial, ritual, used in ceremonies of worship, plants placed in the altar.)
Edible Uses: Very young leaves - cooked and eaten as a side dish with rice. The leaves can be pounded then mixed with water to give a green juice that is used for colouring an Indian pastry made of glutinous rice. Fruits – roasted.
Garden uses: The neat appearance of this shrub ensures it a place in parks and gardens wherever there is a suitable tropical climate. It also cultivated as specimen plant; and large container plant with dramatic sword-like foliage. It makes a good house plants for a Dracaena, though recommend higher light if possible.
Propagation: Seeds. The seeds must be removed from the fleshy fruits. Best results are obtained with fresh seed. Plant the seeds in shallow containers in a quick draining mixture and cover the seeds with green sphagnum moss. Remove most of the moss when the seeds begin to germinate. Keep the containers in a covered, shaded area to protect them from rain damage. The seeds germinate in 2 to to 6 months, and the germination rate is usually only 5 to 10%. The seeds rot easily if the medium is too moist or if not pre-treated with fungicide. Transplant as soon as possible. Fresh seeds lose viability when stored. If seeds must be stored, the cleaned, air dried seed should be put in an paper bag or envelope and placed in an airtight container with desiccant.
