Green IS Group manages and maintains teak plantations within the State of Rondonia, in the north of Brazil.

The Green IS team has been involved with plantation Teak for over 20 years, during which time we have gained a huge amount of knowledge and have tested many methods of cultivation.


Growing Plantation Teak

Seeds are collected between April and August, germinated and planted in nurseries.

It is important to situate the nursery in an area with a good amount of sunlight. The seed beds should be situated under netting, to protect the seeds from direct sunlight, and watered twice a day.

After four to six weeks the seeds will have sprouted and grown to approximately 20cm high. At this point they are ready to be transplanted to the cultivation beds.

Cultivation Beds

The cultivation beds should be in the open air and direct sunlight as this enables the young seedlings to harden in the sunlight and produces a much stronger seedling.

At this stage the seedlings need to be watered three-to-four times a day and after eight-to-ten weeks they are ready to be moved to the plantation.

The seedlings need to be planted in a prepared area where the weeds have been cleared and the soil has been treated to correct its PH balance. This site preparation usually starts one year before planting in the area to ensure that the soil has settled and reached the right balance. The aim is to provide optimum conditions to support growth for the seedlings to flourish.


The best time of year to plant the seedlings is during the rainy period from November through December. Care must also be taken to ensure that the seeds are correctly aligned to maximize the amount of sunlight that they receive.

During the first three years of growth it is important to keep the area clear of weeds and grass. This ensures that the seedlings are not competing for light or nutrients in the ground.

After one month the seedlings will be ‘thinned’ so that only the strongest seedlings, with the best potential for growth, are kept.

Maintaining Plantation Teak


Pruning takes place at the beginning of the third year of growth and then twice a year from that point onwards.

The objective is to eliminate any defects in the wood to give a better financial return.


Thinning aims to free space so that the trees receive more light and therefore grow better and thicken up. Thinning usually takes place three times during the life of a plantation:

First thinning: this is undertaken between years four and six. 50% of the trees are cut down.

Second thinning: this is undertaken between years nine and eleven. Once again 50% of the trees are removed.

Third thinning: this is undertaken between years fourteen to sixteen – at this point any trees that are not reaching the required rate of growth will be removed.



After eighteen years the date for the final cut can be decided – however, the older the trees are, the more value they will have.

The trees for harvest will be tagged and marked and then cut down. They will then be transported to a local mill and processed ready for shipment.

Once the timber has been processed it will then be transported to the port of Porta Velho in the state of Rondônia and packed into shipping containers before being shipped to Manaus, this is where the customer will take possession and pay for the product in full with all the documents required to ship Freight on Board (FOB).
