Propagation and Care

Cassia fistula can be propagated by seed and vegetatively through cuttings and air layering.  April shower or Golden Shower trees can grow between 10 meters to 25 meters in height.

The key is collecting the seeds when they are mature but not overripe ( dark brown color). The best time to harvest the seed pod, Are the seed pods produce over last year’s blooming season.

The seeds germinate best when the days are long with extra hours of sunshine. Rinse the seeds in warm water to remove the dark pulp.

One can soak the seed in  water for about 24 hours. Then try to scar the seed by rubbing them on cement or any hard surface in order to scar the seed.

Try to plant each seed in its own gallon pot with drainage holes on the bottom. Fill the pots with lightweight, sterile medium. Sow the seeds 1 to 1.5 inch (2.5 cm to 3 cm) deep, then position the pots in a warm, indirect light condition.

Depending on the temperature condition, one can germinate the seedling between 3 weeks to about a month.

Propagating via seeds can be long process and can take between 3 to 5 years before it start blooming.

One can place the seedling on ground when the seedling reach at least 1 year, this will hasten the growth.

One must not forget to occasionally apply organic (compost) and inorganic fertilizer every two or three weeks interval.

Do not forget that regular pruning of this tree is needed before it get too tall. Enjoy the annual blooming season by having a viewing party or photo session with the tree.
