Add a touch of the tropics to your backyard by planting a frangipani in a container (Plumeria). This tropically-derived, dwarf tree is an excellent choice for growing in a container. The blooms, which have a pleasantly sweet perfume, appear in a kaleidoscope of hues, and they compliment the huge, green leaves. When cultivated in the ideal circumstances, maintenance for a potted frangipani is simple, and the amount of trimming that is required is low. The tiny tree will do well in areas with a higher risk of frost if it is provided with the necessary protection.
Plumeria Climate Requirements
Frangipani grows best in conditions that are frost-free, dry, and warm. It is able to withstand the elements when planted outside in Sunset’s Climate Zones 12, 13, 19, 21 through 24, and H1 and H2. Container gardening is the way to go for those who live in warmer climates yet want to cultivate it. When the temperature drops below 32 degrees Fahrenheit, bring any plants that are kept in pots indoors.
According to the University of Florida IFAS Gardening Solutions, optimal performance and flower production may be achieved by cultivating the plant in full to partial sunlight. According to the South California Plumeria Society, the most profuse blooms are produced by trees that get between six and eight hours of sunshine.

Planting Frangipani in Pots
Frangipani should be grown in containers that have drainage holes. Cuttings that are 12 inches or less in length thrive well inside the 1 gallon containers. Use bigger pots, such as those measuring between 3 and 7 gallons, for planting larger trees. These provide sufficient room for the roots to grow in the correct direction and are big enough to maintain the tree standing straight, which is important since older trees may become top heavy. Utilize a potting mix that allows for adequate drainage, such as a combination of two parts cactus mix and one part perlite.
Watering and Fertilization
The frangipani plant cannot survive in situations that are always wet and damp. Root rot is caused by wet circumstances, which ultimately results in the death of the tree. Water the tree once every week to two weeks throughout the growth season, which begins in the spring and continues until early October. Plants are dormant throughout the winter months, and they only need water if the soil has become completely dry. Apply fertiliser beginning in the spring and continuing through the fall, doing so every three to four months. The University of Wisconsin–Madison recommends making use of a water-soluble mixture that is rich in phosphorus (the middle number), since this will encourage blossoming. Pour water over the soil after mixing 1 to 2 tablespoons of a 10-30-10 or 10-52-10 formula with the water.
Pruning Frangipani Species
Only prune frangipani if you want to regulate its growth or form, or if you want to remove branches that are damaged or sick. Use loppers or bypass pruners. Remove any excess length from the branch so that it lies flush with its connecting point on a major branch or trunk. By commencing the initial cut roughly 12 inches from the main branch, you may remove long and heavy branches from the tree without peeling the bark or causing any other damage to the tree.
Cut through one third of the branch’s length, working your way up from the bottom. Just about an inch and a half should between the first and second cuts that you make. Remove about a third of the branch’s growth by making cuts in the opposite direction of its growth. After that, cut the branch off so that it is flush with the trunk; this should allow it to fall without causing any harm to the tree. Frangipani may be pruned at any time of the year, however winter trimming will result in less blooms in the spring.
Diseases and Pests
There aren’t many pathogens that can affect frangipani. Plumeria rust causes the undersides of leaves to get covered in a powdery orange substance or blisters (Coleosporium plumeria Pat.). Rust has a little risk to human health, but it may lead to defoliation of plants. Follow the instructions on the fungicide’s package when administering treatment for serious issues.
It is possible for black sooty mould to blanket the leaves when pests such as aphids, scale, mealybugs, or whiteflies are present. The issue with mould can be controlled in its entirety by eradicating the bug problem. Apply a pesticide and be sure to follow all of the guidelines. Plumeria stem borers are pests that eat the wood of branches from the inside out, ultimately leading to the branches’ demise. Treatments designed to kill insects are useless. Remove any infected branches from the tree. The frangipani plants that are under the greatest stress are the ones most likely to be affected by pests and diseases.
