Care Tips for Thevetia Peruviana

Light Requirements:

• Outdoor: Thevetia peruviana thrives in full sun but can also tolerate partial shade. For optimal blooming, it is best planted in a location where it receives several hours of direct sunlight each day.
• Indoor (Container Growing): If grown indoors, place the plant near a bright window with plenty of sunlight. It can adapt to indoor conditions but may require additional lighting to bloom.

Watering:

• Outdoor: Water regularly during the growing season, allowing the soil to dry out between waterings. Once established, the plant is drought-tolerant and requires minimal watering.
• Indoor: Water when the top inch of soil feels dry. Ensure the container has good drainage to prevent waterlogging, which can lead to root rot.

Soil:

• Soil Type: Thevetia peruviana prefers well-drained soil and can thrive in a variety of soil types, including sandy, loamy, and clay soils. It tolerates both acidic and alkaline pH levels.

Pruning:

• Pruning Needs: Pruning is not typically necessary, but you can trim the plant to maintain its shape or remove any dead or damaged branches. Light pruning after flowering can encourage bushier growth.

Fertilization:

• Feeding Schedule: Feed the plant with a balanced, slow-release fertilizer during the growing season (spring and summer) to promote healthy growth and abundant blooms.
