Planting Method

In plantation forestry, it is essential to carefully assess the ecological conditions at the planting and to assess whether a potential species will survive and grow. Aquilaria spp. is not demanding regarding soil and climatic conditions, occurring naturally in all ecological zones and on a variety of soils (avoid clay soil). However, many planting have died back after 3 ~4 years of establishment, seemingly due to stagnant water. Planting on sloping lands is therefore recommended.

To reduce the mortality rate, seedlings are ready to transplanting into ground when achieving 60~90cm height. Older seedlings might not be good due to root coiling in the confined polybag if polybag is not big enough.

1. Planting hole preparation 40cm x 40cm x40cm. Leave for 2 ~ 3 weeks, with rain and sunshine repeatedly, the soil is oxygenated, very helpful for root growth.

2. Add 150~175ml CIRP. If the soil is hard, add 10~15% coco peat to loosen the soil mixture. Coco peat can absorb large volumes of water. Generally Coco peat can absorb water about half of its volume and 5 to 6 times its weight. Coco peat has great oxygenation properties. Other source of phosphorus can be obtained from TSP and DAP, but to be used with caution due to its causticity, having solution pH 1~3 and 7.5~8 respectively. Over dosage may damage the seedling. Advantage of TSP and DAP are both highly soluble and thus dissolves quickly in soil to release plant-available phosphate.

3. Add 15% organic fertilizer, and 20 grams of Funadan to minimise insect attack.

4. Mixing the mixture to small particle possible.

5. Refill the planting hole to appropriate level. Cover the seedling not more than 2” above planting surface. Deep planting will rot the stem in long run.

6. Remove polybag and place seedling into the planting hole.

7. Cover the seedling and chamfer the cimcumference to improve water catchment.

8. Chamfer the circumference of planting hole to improve water catchment.

9. Done. This method might be very tedious and time consuming, but the surviving rate is 99%.
