Plumeria Obtusa is a small, deciduous tree that typically grows up to 10-15 feet tall. It is well-known for its fragrant, five-petaled white flowers with a distinct yellow center, which bloom from spring to fall.

How to Care for Plumeria Obtusa?
Caring for Plumeria Obtusa is relatively straightforward, making it a favorite among garden enthusiasts. Here are some tips to ensure your plant thrives:
- Light Requirements: Plumeria Obtusa loves sunlight and should be placed in a spot where it receives at least six hours of direct sunlight daily. If grown indoors, ensure it’s near a sunny window.
- Watering: The plant prefers well-drained soil and should be watered deeply but infrequently. Allow the soil to dry out between waterings to prevent root rot. During the winter, reduce watering as the plant goes dormant.
- Soil: Use a well-draining soil mix, preferably sandy or loamy soil. Adding perlite or coarse sand can improve drainage.
- Fertilizing: Feed the plant with a balanced fertilizer during the growing season (spring and summer). A fertilizer high in phosphorus will promote blooming.
- Pruning: Prune Plumeria Obtusa in late winter or early spring to shape the plant and remove any dead or diseased branches.
How to Propagate Plumeria Obtusa?
Propagating Plumeria Obtusa is relatively easy and can be done through cuttings. Here’s how:
- Choose a Healthy Stem: Select a healthy, mature stem that is about 12-18 inches long.
- Cut the Stem: Using a clean, sharp knife or pruning shears, cut the stem at a 45-degree angle. Remove any leaves from the bottom half of the cutting.
- Let It Dry: Allow the cutting to dry for a few days in a shaded area. This helps prevent rot when planted.
- Plant the Cutting: Once the cut end has dried, plant the cutting in a pot with well-draining soil. Water it lightly and place it in a sunny spot.
- Care for the Cutting: Water the cutting sparingly until roots develop. Once rooted, care for it as you would a mature Plumeria Obtusa.
