Prune the plant occasionally to maintain a neat and manageable shape. 

Be sure to do this during the winter season, when the plant is naturally dying down. 

Prune it a third back or all the way to the ground.

Prune off the seedpods that develop after flowers are spent to encourage profuse and frequent flowering. 

Some supplemental water every week or two during the blooming period may also encourage more flowers.

How to Propagate Caesalpinia Mexicana Plant

The propagation of this plant is done using seeds.

Begin by gathering the seed pods and placing them in a paper bag. 

Be sure to store the bag in a dry and dark spot to let them dry out and open up. 

Once the pods open, take out all the hard seeds. 

Take sandpaper to smoothen the surface of all seeds. 

Do it gently to avoid damaging the seeds. 

This process is referred to as seed scarification and enables the seeds to absorb water for the germination process.

Next, soak the seeds in warm water for a few hours and plant them under a sunny spot in a well-draining soil mixture. 

You may also plant them in a container by using general potting soil. 

Make sure the seeds are planted half-inch deep in the mixture.

Water the seeds to provide moisture and make sure to keep the soil moist until the germination is done. 

Once the seedlings become tall enough, you may allow the soil to slightly dry between the watering. 

When the plant reaches its mature height, it becomes drought tolerant and prefers the soil to dry out before the next watering.

Therefore, with proper care, the risk of infestation gets low.
