A Complete Analysis of the Latest Growing Conditions for Agarwood Trees

The agarwood tree is a tropical and subtropical evergreen tree, one of the world's rare and precious medicinal plants. It is a Class II nationally protected plant in China and also an internationally protected tree species. It prefers to grow in low-altitude mountainous areas, hills, and open sunny spots in sparse forests along roadsides. Below, let us take a look at what the growing conditions for agarwood trees are!

Temperature Conditions

The agarwood tree prefers a high-temperature environment and requires an annual average temperature above 20°C, with the highest temperature reaching above 37°C, in order to grow and develop well. It can tolerate a minimum temperature of 3°C, and can also adapt to brief periods of low temperature and frost in winter.

Light Conditions

Agarwood tree seedlings are shade-tolerant and cannot withstand exposure to strong sunlight, but the shade should not be too heavy; 40%-50% is suitable. Once mature, it prefers light, as light ensures normal flowering and fruiting, plump and robust seeds, and promotes the formation of high-quality agarwood.

Soil Conditions

The agarwood tree can grow in acidic sandy loam, yellow loam, and red loam. In the wild state, it grows slowly and poorly in barren clay soil, but compared with environments with good water and fertilizer conditions, the wood is more solid, the fragrance is richer, the resin is abundant, and it is easier to form agarwood, with better quality. However, under conditions of deep, fertile soil, the wood and bark tissues are loose, less resin is secreted, very little agarwood forms, and the quality is also poor.

Moisture Conditions

The agarwood tree prefers moisture and is drought-tolerant. It requires an annual rainfall of 1500-2000 mm. In relatively moist environments, the height and thickness growth of Aquilaria sinensis is fast, while on dry, barren slopes, growth is poor, but it can still survive.
