Plumeria Care: Frequently Asked Questions
Expert answers on rooting, growing, and winterizing your Hawaiian Frangipani.
🌱 Rooting & Planting Cuttings
How do I plant my fresh cutting?
Use a 6-inch pot with a well-draining mix (Cactus mix is best). Dip the cut end in water (and rooting hormone if you have it), then plant it about 3 inches deep. Firm the soil around it so it stands up straight.
When should I water my new cutting?
The Golden Rule: Do not water immediately! The cutting has no roots to drink the water, so it will rot. Give it heat and light for the first 3-4 weeks. Once you see leaves sprouting, that means roots have formed. Then you can start watering once a week.
What kind of soil should I use?
Plumerias hate "wet feet." Use a Cactus & Succulent Mix or a regular potting soil mixed with 30% Perlite or Sand. Good drainage is the secret to a healthy tree.
☀️ Sun, Water & Fertilizer
How much sun does a Plumeria need?
They love the sun! Aim for 6 to 8 hours of full sun per day. The more sun they get, the more they will bloom. If you live in a very hot desert climate (over 100°F), a little afternoon shade is helpful.
What fertilizer should I use?
We recommend using a Blooming Osmocote (time-release fertilizer). Apply it once every 6 months. Look for a fertilizer with a high middle number (Phosphorus), like 10-30-10, to encourage big, colorful blooms.
❄️ Winter Care & Storage
What do I do when it gets cold?
Plumerias are tropical and cannot survive a freeze (temperatures below 32°F). When night temperatures drop below 40°F, it's time to bring them inside.
Can I store them in a garage or closet?
Yes! This is called Dormancy. The plant will drop its leaves and go to sleep. You can store the pot in a dark garage, closet, or basement. Stop watering completely during this time. Bring it back out in Spring when the danger of frost has passed.
🚑 Troubleshooting Problems
Why is my Plumeria stem soft?
A soft or "squishy" stem usually means Stem Rot. This happens from overwatering or frost damage.
The Fix: Cut the stem down until you see clean, solid white wood (no brown). Let the fresh cut dry (callus) for 5-7 days, then replant in fresh, dry soil.
Why are the leaves turning yellow and falling off?
If it is November/December, this is natural! The plant is going dormant for winter.
If it is Summer, it could be a sign of overwatering (root rot) or spider mites. Check the underside of the leaves for tiny pests.
