Durians can be produced all year round in Thailand. Due to the popularity and the value of the fruit, the Thailand government together with the farmers had developed the technique that will make the durians bloom all year round.
The farmers will only harvest when durians reach a certain age by checking the appearance of durians, and count the numbers of days from the durian flowers are blooming which are different by types below:
1) Monthong: 140-150 days
2) Chanee: 110-120 days
3) Kan Yao: 120-135 days
4) Kradoom: 90-100 days
However, the number of days counting may vary a bit by the geography and the weather (i.e. Hot and dry climate, durians will reach the age sooner, the rain will slow down the aging process of durians).
