Throughout the active growth season, which generally spans from late spring through early fall in tropical regions, plumeria demands consistent and thorough watering. It’s imperative to water deeply during this period to guarantee the plumeria roots have access to ample moisture.


As autumn arrives, bringing a decline in temperatures, the pace of plumeria’s growth naturally decelerates. In response to this seasonal shift, it becomes prudent to decrease the frequency of watering.

This adjustment enough water also serves the purpose of granting the plant an opportunity to transition into a state of dormancy, a critical phase in its life cycle early summer, where temperatures drop and it readies itself for the forthcoming winter. During this transitional period, mindful watering practices play a pivotal role in facilitating a smooth shift for the plumeria, helping it conserve energy and prepare for the colder months ahead.


In winter, plumeria enters a dormant phase in numerous regions. Throughout this dormant season, it is advisable to exercise restraint in watering, adopting a sparing approach. Allowing the soil to experience intermittent drying between regular watering up sessions is a key practice during this dormant period. This strategy aligns with the plant’s natural behavior during winter, conserving moisture and ensuring it remains in a state of rest until the return of more favorable growing conditions.

Best Practices for Watering Plumeria

To ensure optimal growth, bloom and blooming, follow these best practices when watering plumeria:

Water Early in the Day

Watering your plumeria in the morning is an advantageous practice as it permits new leaves on the plant to absorb moisture ahead of the day’s rising temperatures. Conversely, it’s advisable to refrain from evening watering to avert prolonged soil moisture, a situation that can potentially trigger fungal problems.

By adhering to this guideline, you optimize the chances of maintaining a healthy and thriving plumeria while sidestepping the pitfalls associated with excess moisture lingering in the soil during the night.

Water at the Base

Directing the water flow to the base of the plant while avoiding wetting growing tips of the leaves is a prudent approach. Moist leaves can become vulnerable to fungal diseases, making this careful watering technique a preventive measure against such issues.

By ensuring that water reaches the root zone without moistening the foliage, you contribute to the overall well-being of your plumeria, safeguarding it from potential fungal threats and promoting its sustained health and vitality.

Use a Soaker Hose or Drip System
