The coconut varieties cultivated in the seed garden are mainly Aromatic Green Dwarf (imported long time ago from Thailand); Macapuno tall from embryo vitro culture; hybrids between Malayan Red and Yellow Dwarfs and Makapuno Tall (pollen imported from the Philippines). During the period 2011-2015, about 160 000 seedlings were produced y IOOP seedgarden. Presently the cost of seednuts is partially supported by the government and they are sold to Vietnamese farmers at 2 USD per piece. Be care that the germination rate of the Aromatic Green Dwarf is generally lower than those of most other Dwarf coconut varieties, and that only 50 to 60% of the AROD seednuts will finally give good seedlings to be planted in the field.

In some emasculated MYD inflorescences, we saw a strange accumulation of dried sap at the bottom of the female flowers. This could be due to insect attacks. The same was also observed on a Xiem Green Dwarf in an hotel of Ben tre city, so it seems that this pest is widely distributed.
A few MYD palms have a strange habit of the terminal parts of the upper leaves. Boron deficiency was suggested as the cause but, in the opinion of Dr R. Bourdeix, it is very rare to observe boron deficiency on adult palms.
The seed garden is far from the see and some problems of Chlorine deficiency may happen. It is advised to sometimes provide salt to palms to avoid this problem.
Coconut palms are inter cropped with commercial Jack fruit trees, and some large new plots are inter planted with dragon fruit and coconut palms. Some plots are planted with rubber trees. In the future, it could be useful to plant germplasm collection of jack fruit, Dragon fruits and other crops instead of commercial material only. This will need agreements between the various Vietnamese institutions presently working separately on different crops.
