Tuberose Plant Care 

Tuberose care should be easy for gardeners as the plant requires low maintenance. It has simple watering and lighting needs. And it can grow in almost all soil conditions. The plant also has some tolerance for pests. 

Lighting Requirements For The Tuberose Plant 

The best lighting for planting tuberose is full or direct sunlight. They require at least 6 to 8 hours of direct sunlight each day to thrive.

It is recommended that you grow tuberose next to a south-facing window. There they can receive all the sunlight they need to thrive. You can also grow them right next to a west-facing window but avoid north-facing windows.

The water being used should be tepid and dechlorinated. Avoid using tap water, instead, use rainwater as it is pure and safe for the plant’s root.  You can also try leaving tap water out in the open for a day before use. It should lose its chlorine content and be safe for use. 

Soil Requirements For Tuberose 

A good batch of well-draining loamy or sandy soil should be perfect for the tuberose flower. Ensure it is mixed with organic compost as the soil should be rich.  It should also be able to retain moisture.  Try mulching the soil to keep it moist.
