How Much Water Does Plumeria Need?

Plumeria is a tropical flower that thrives in tropical places. They grow best when they receive full sun in well-drained soil. There is no definite measurement of how much water you should give your plumeria.

However, as a golden rule for watering plants, at least one inch of water will suffice every week or in between by allowing the soil to dry. It is essential to water gradually for the ground to absorb the water.

This might be different when plumerias are in the ground or pots.

In The Ground

Plumeria cultivated on the ground can be watered weekly. They thrive best in well-draining soil and are drought-tolerant, which is why they need occasional watering.

It is advised to water the plant at least twice a week in the summer and let the soil dry in between to prevent overwatering plumeria.

In Pots

Plumeria thrives in pots and can be moved around with ease.

Use a pot with at least a 6-inch diameter and good drainage holes when planting plumeria. When watering plumeria in pots, choosing a pot with sufficient holes for the drainage system is essential.

Poor drainage may affect the plant and cause its roots to rot. It is recommended to be watered every 1 to 2 weeks. Light misting may suffice if your plant begins to look somewhat dehydrated indoors.

During Summer

You might consider frequently watering your plumeria in the summer out of concern that it won't survive. Overwatering, however, can cause the roots of your plants to rot.

Keeping it moist is enough while letting it dry in between watering.

Watering at least twice a week during the summer may suffice. Misting is also ideal during the summer, but it should only be done in the foliage, not the flowers.

During Winter

Plumeria goes dormant during the winter. It is best to avoid watering your plumeria when the temperature drops, as this may kill your plant.

A sign that your plumeria is dormant is when they don't have leaves. During its dormancy, it usually does not require watering as this will cause its root to rot.

Fertilizing is also unnecessary; it is best to leave them alone until they bloom in the spring.

Where Do Plumeria Grows Best?

Plumerias will start blooming once they reach 2 to 3 years old. They also enjoy being exposed to at least 6 to 8 hours of full sun and can also tolerate partial shade.

The best soil to grow plumeria is well-draining soil that is slightly acidic with a pH level of 6.0 to 6.7 when growing in pots. They should also be planted facing the south, where they can get ample sunlight.

The ideal temperature during the day time for this plant would be 65°F to 80°F (18°C and 26°C) and 50°F (10°C) for the night time.

If the temperature drops below this, it's best to bring your plant indoors, as plumeria thrives best in tropical climates and does not enjoy low temperatures.

When placing plumeria indoors and your home does not have enough light sources, placing the plant under fluorescent light for at least 14 to 15 hours daily will suffice.

Although plumeria thrives in full sun, it is susceptible to sunburn, which causes its stem to turn yellow and wrinkled. Giving your plant some partial shade may be helpful to avoid this.
