Before we head on to the fertilizers, here’s some jargon recap for beginner gardeners.
NPK stands for nitrogen, phosphorus, and potassium respectively. So, when you see numbers 10-10-10 that is the minimum NPK content of fertilizers.
Manufacturing companies do not declare the real NPK ratio of their fertilizers to prevent their competitors from copying their formulas. The NPK formulation is just to give you an idea about the contents.
Now, check out the following fertilizing that is suitable for every type of gardener. Either you’re an organic plumeria grower or a beginner in the planting hobby, you’ll surely find that will suit your preferences.
1. Grow More Hawaiian Bud and Bloom

What You Need To Know About Plumeria?
Plumeria or frangipani is an exotic shrub tree mostly found in tropical areas. It is popular as a part of the Polynesian flower garland called lei.
In the US, it is commonly grown in a pot in zones 10 and 11. Plumeria loves full sun and can survive short periods of drought.
Compared to other sensitive flowers, plumeria is easy to grow. It is also among the most fragrant flowers that spread its aroma at night. Every variant of plumeria has a different smell but the yellow ones are the most fragrant of all.
It can grow as tall as 20 feet in some countries. However, the indoor plumerias are grown for up to 6 feet to help it focus on producing more flowers than growing its trunk. It can also overwinter and should be kept indoors during winter for its dormancy period.
Plumeria blooms every May to November. Since it is a tropical plant, it can’t tolerate cold temperatures. So, when the first frost comes make sure that they are already relocated indoors.
- It needs slightly acidic soil
- Best soil mixture us ⅓ peat moss, ⅓ Coir, and ⅓ Perlite
- Best soil PH is between 6.5 to 7.0
- Plumeria needs 6 to 8 hours of full sun exposure
- However, keep it away from the scorching afternoon sun by placing it in a slight shade.
- Too much irrigation can cause root rot. Make sure to let it dry out in between your watering routine.
- Potted plumeria needs daily watering
- They are better off drier than moist all the time.
- Reduce watering plumeria in mid-fall as they start going dormant.
- Plumerias need phosphorus-rich fertilizers to help them develop more flowers than focus on growing their trunk and leaves. Nitrogen encourages growth. That’s why the ideal fertilizer must have a lower nitrogen content and higher phosphorus content.
- Stop fertilizing them 45 days before winter to allow them to prepare for their dormancy period.
Pest Control Requirements
- Plumeria attracts pests when they get too dry or develops fungus from nearby spores when the leaves are left wet. They’re prone to rust fungus when there is not enough air circulation and there is too much moisture.
- Common pests in plumerias are:
- Moth larvae
Tips in Growing Plumerias
Here are some tips from the professional growers of plumerias:
- You can use Epsom salt or lime to neutralize the acidity of the soil.
- The milky sap from plumeria can irritate the eyes and skin. It is also poisonous so make sure to wash your hands immediately upon contact with the sap.
- Bring your plumerias inside the house when the temperature drops to 50 F degrees.
- Use insecticidal soap to deal with harmful insects and diatomaceous earth for the slugs.
