Tengo un hibiscus rosa sinensis de mas de 30 años repleto de flores y quisiera sacarle semillas pero no lo logro de ninguna manera ya que después de la caida de la flor a los 7-10 dias se cae el capullo. Que es lo que estoy haciendo mal ? ...es como que la capsula no llega a desarrollarse . Si algún miembro me puede ayudar en saber que es lo que esta pasando se lo voy agradecer. Gracias por su atención.

You say that this Hibiscus is 30 years old, has it never produced seed? If it has always dropped it's pods after blooming then it probably always will. Hibiscus are hybrids and many will just not produce seeds. One possibility is that it is self-sterile and can not fertilize itself. If their were other Hibiscus around it may be possible to pollinate it with a different Hibiscus, but there is no guarantee.

Thirty years old could mean a garden variety which doesn't set seeds easily. I think the problem could be that you are not pollinating them. Insects don't pollinate hibiscus and, if that happens, it would be just by accident.
You need to do manual pollination and wait, and wait. There's no trick but the first 20 o 30 times you try to pollinate you will fail. After that time, doing the same, you will start to have success. Nevertheless, garden varieties are dominant so, even having seeds from them, their offsprings will be likely the same as pod parent.

Now in spanish.
Por como lo cuentas no creo que estés polinizando las flores sino esperando que se polinicen por sí solas, algo que no va a ocurrir pues los insectos no son polinizadores de hibiscos y, si en un momento dado lo hacen, será por accidente.
Necesitas polinizar manualmente una flor, llevando el polen de otra flor al estigma de ésta. El éxito viene con la experiencia y ésta simplemente es intentarlo muchas veces. Después de 10, 20, 30 veces empezarás a tener resultados. Ahora bien, las variedades de jardín son dominantes, lo que quiere decir que su descendencia va a ser prácticamente idéntica a ella. No esperes colores espectaculares.
