According to the Department of Agriculture, Teak tree cultivation is very suitable in Indonesia, because some areas have tropical climate. Teak can be planted in Java, parts of Sumatra, Sulawesi and Maluku. Teak trees will grow well in areas with rainfall between 1,500-2,500mm/year, either in the lowlands or highlands, a good planting location in areas with an altitude of 10-1000 m above sea level, and has a light intensity of 75-100% and a Ph. Soil 4-8. The good soil for teak tree growth is sandy loam soil type, avoid swampy and rocky soil.
Good teak seedlings are six months to one year old, derived from seeds or from tissue culture. Each has advantages and differences. For industrial plants, seedlings from tissue culture are better than seedlings from seeds.
Maintenance is needed in the first year to the third year, when the teak tree must survive from the weather and pests. After that, routine maintenance such as clearing the grass and weeds as well as pests and diseases. Giving fertilizer, pesticide or fungicide at the beginning of growth will make the teak trees grow healthy and strong.
The Java Teak plantation in Bumisari is a GoldTeak pilot project, on 2.6 hectares of former rice fields. With regular care and maintenance, teak trees grow well. Although the tree circumference is not large and has many branches, the quality of Java teak wood is also very good, light brown to dark brown in color, strong and not easily broken or deformed. With a unique texture and motif, teak wood is widely used for furniture. With the price of teak wood continuing to rise, planting teak trees is a good option of investment.
