When durian is ripe, it can be judged by its appearance, smell and sound.

1. Look at the appearance: the shell is yellow, press two adjacent spikes, and you can get close with a little force, so it is mature and edible.

2. Smell: A strong fragrance overflows near the top trunk, which means it is ripe and edible.

3. Listen to the sound: when the durian shell is knocked on the back of the knife, the sound is crisp and empty, and it is mature and edible.

breeding precautions:

durian trees should focus on applying fertilizer once a year, that is, spring bud drawing fertilizer, summer fruit swelling fertilizer and pre-harvest fertilizer, especially fruit swelling fertilizer. Deep application of organic fertilizer after fruit picking. Because durian trees have strong germination ability, attention should be paid to shaping 1-2 years after planting, and pruning should be done in time after fruit picking to maintain a good tree shape.

durian fruit is ripe and can be harvested when it turns orange yellow or orange red. After harvest, the fruit can't be eaten directly, and it needs 4-7 days to ripen and expect the flesh to be soft before eating. Because durian can only grow and bear fruit in the high temperature climate all year round, even in the equatorial region, the highland above 6m above sea level can not grow durian or bear fruit because of the temperature drop.
