First, read the English article below.

If you get a period of dry weather, water the sandalwood tree. Twice per week, give it half a litre (.5 quart) of water. It is best to water sandalwood in the evening, which prevents excessive evaporation. If your area gets below the recommended range of 850-1200 millimeters (33-47 inches) of rain per week, you’ll need to water the plants regularly. If the host species begins to overshadow the sandalwood tree, you’ll need to prune it back. Otherwise, the sandalwood tree will not get enough light. Prune the host species so that it is a little bit shorter than the sandalwood plant, so that the sandalwood gets adequate sun. Since herbivores love the taste of sandalwood trees, you’ll want to protect your plants. Avoid damage to your sandalwood tree by putting up a fence around the perimeter, which should help prevent herbivores from eating it.

Tưới cây trong suốt mùa khô. Cắt tỉa cây chủ. Bảo vệ cây đàn hương khỏi các loài động vật ăn cỏ.
