When And How Often Do I Fertilize Plumeria?

The best time to fertilize plumeria is in the early spring. It can be continued until the end of the summer. The frequency of fertilization depends on the stage of the plant growth.

The younger plants require less fertilization while older ones require more. The younger plants do not need fertilization until the top inch of the soil is completely dry.

Younger plants prefer to be fertilized every 3-4 weeks while the established ones need feeding once every other week.

Water the plants deeply and drain the excess water to prevent nutrient leaching. Also, avoid fertilizing once the growing season is over. Avoid using fertilizers during the dormant season.

Liquid Vs Granular For Plumeria: Which is Better?

Both liquid and granular fertilizers work for plumerias. You may choose one depending on the type of fertilizer, ease of application, and your personal preferences.

Granular fertilizers are available as small pellets that can be mixed into the potting mix before planting or applied to mature plants around the drip lines.
