To establish this practice, the land-user puts into consideration the following: pitting at a depth of 3.5 inch, trees to be planted and spaced at 3 metres x 3 meters using the following inputs: tree seedlings, wheelbarrow, hoes, pangas and labour.
During the process, the tree stems are cut at 30cm length and planted. The stem is placed upright and later covered with soil. If there is adequate rain then some tip of the stem is left exposed but if rainfall is inadequate then the stem tip is covered in order for the plant to have enough moisture for its growth. It takes two weeks for the tip to get exposed on the surface when fully covered. The plant automatically appears with two leave lets.
The leaves when exposed to excessive sunlight can dry up and this retards its growth. This may require watering by the land user. At the early stage, the teak plantation can be inter cropped with beans and other crops such as sesame since the teak plantation has not yet formed a big canopy. This can be done for two years and later only slashing within the plantation needs to be done to maintain the plantation. The dry fallen leaves also kill weeds hence easing maintenance work. The trees are to be protected from fire outbreaks during dry season. In the month of November, fire lines are to be created and the dry leaves collected to mulch the plantation.
The cost of establishing a Teak plantations is high in the first 2-3 years but reduces significantly after first thinning. The cost of weeding can be reduced by spot-weeding of seedlings up to age 3 years, after which slashing or spraying with herbicides, usually Round-up is used for weed control. Wood from thinning is also sold as firewood or construction poles to recover some the establishment costs.
Shedding of teak leaves is heavy during the dry season and this causes a risk of fire. It’s advisable at this stage that the land user puts in place fire lines, an open space of 6 meters to separate the plantation into compartments in order to restrict fire from spreading from one part to another part.
Teak plantations are good at responding to dry conditions and can provide high-quality timber which in turn provides income. Teak trees provide hardwood timber, poles and modify the micro-climate through evapotranspiration. Fencing is done using bulb wires to avoid damage by wild animals and encroachments. The teak trees occupy land for a long period of time that can be used for other purposes like planting food crops. The piled dry teak leaves may harbour dangerous animals like snakes. Community members also complain about too much rainfall brought about by the plantation.
