Dragon fruit pollination methods There are three methods of dragon fruit pollination: wind-mediated pollination, insect pollination, and artificially assisted pollination. Dragon fruits maintained at home are generally artificially pollinated, while wind-induced pollination and insect pollination are used in the wild. Is dragon fruit self-pollinated? Dragon fruit has self-pollination, but its self-pollinated fruit setting rate is low.

After pollination of dragon fruit, the flower seat remains yellow for about five days, which means that pollination has been successful. If pollination fails, the color of its flower seat will turn yellow and eventually fall off with a slight touch.
The best time to pollinate dragon fruit is during spring sowing. On sunny days, it usually blooms around 6 p.m.. The anthers of dragon fruit begin to crack open and release pollen. The color of the corolla begins to fade and close around 12 p.m., and the corolla closes at 3-4 p.m. Of course, the length and morning and evening of dragon fruit blooming will also vary according to local temperature conditions. Usually, 6-10 a.m. is the time when female flower stigmas and male flower pollen are most active during the physiological period, so this time is the most suitable for manual pollination. Pollen germination ability is the strongest when the pollination temperature is 21-30℃.
Dragon fruit pollination methods Dragon fruit pollination methods: self-pollination, cross-pollination and regular cross-pollination. When pollinating, collect the pollen into a container and apply it to the female style. How to artificially pollinate dragon fruit? The main method is to manually point the collected pollen. That is, fully mix the collected pollen evenly, use a brush to dip the pollen and point the stigma, so that the pollen can be evenly spread on the core of the column.
