Botanical Name: Tectona grandis Common Names: Saka, Burma teak, Rangoon teak and tekka
Teak tree has an erect trunk, a cylindrical bole and an umbrella like beautiful crown. It tends to be fluted at the base. Leaves are simple, opposite, large i.e. 30 to 50 cm x 25 cm, round, broad, pointed and thick in structure. New leaves appear in May-June. Teak flowers, which appear in July-August, are branched, 50 to 100 cm long whitish cymes. Individual florets are small and round with diameter of about 4 mm. In six to seven years it can grow up to a height of 30 m and a girth of about 2-3 m. It weights nearly 20 kg to a cubic foot and its grains show beautiful patterns.
Soil: Teak can grow on a variety of soils. The quality of its growth, however, depends on the depth, structure, porosity, drainage and moisture-holding capacity of the soil. It develops best on deep, well-drained and fertile soils, especially on volcanic substrata. The optimal soil pH is between 6.5 and 7.5. The calcium content of the soil is also an important factor; calcium deficiency in the soil results in stunted growth of teak.
Watering: A phenomenon of water blisters may also develop in teak trees grown under irrigated conditions. Such trees may appear quite healthy from outside but the inner heartwood may develop rot due to storage of excess water that increases the spread of fungi which may further damage the tree.
