Generally about 24 to 36 hours, the anthers can be dried and cracked and pollen scattered; at this point, the pollen can be placed in a dry vial together with the anther wall. 2 Pollination: Pollination should be conducted from 9 a.m. to 15 p.m. daily. Either use a pencil eraser head or use iron wire and wooden stick to put on the valve core to capture the pollen and give it to the stigma that just opened the flower.
