How to Grow Potted Frangipani (Plumeria)? A Full Guide to Growing Methods and Precautions

Frangipani (Plumeria) originates from Xishuangbanna, China, and some Southeast Asian countries. Its flower shape is unique: the white petals have a touch of yellow in the center, just like an egg, white on the outside with a yellow yolk wrapped inside, which is why it got this name. So how exactly do you grow this beautiful frangipani? Let's introduce its growing methods below.

How to Grow Potted Frangipani

1. Mix the potting soil in the ratio of garden soil : leaf mold soil : river sand = 4:4:2, and you can also add an appropriate amount of decomposed organic fertilizer. When planting, you can slightly expose the roots when potting up. After planting, place it in a shady spot first, then move it to a sunny spot after 15 days.

2. In summer, let it be exposed to full sun so the branches can grow thick and strong. In the high-temperature seasons of summer and autumn, which coincide with the peak growing and blooming period of frangipani, water it 1-2 times every evening. If it rains in summer or autumn, promptly pour out any accumulated water in the pot. Pay attention to checking whether the potting soil is dry or moist, and water according to the principle of watering when dry and stopping when wet.

If it rains, promptly pour out the accumulated water in the pot to prevent root rot. During the growing season, apply a thin layer of decomposed fertilizer once every 15~20 days. Before flowering, apply a thin phosphorus-based fertilizer 1-2 times. If the fertilizer is insufficient, it will bloom less or not bloom at all.

3. After it drops its leaves in autumn, potted plants in the north should be moved indoors to a sunny spot in mid-to-late October to protect them from freezing and keep them warm for the winter. A room temperature above 5°C allows it to overwinter safely. Pay attention to ventilation and light. The room temperature should preferably be above 10°C; low temperatures and poor indoor ventilation will cause the plant to drop its leaves. Water indoors once every two weeks.

4. In winter, restrict watering and stop fertilizing to keep the plant in a dormant state. Maintaining room temperature at around 10°C helps frangipani overwinter safely. If you need to dwarf the plant, you can prune it appropriately after the leaves drop each winter, and you need to repot it once every spring, renew the potting soil, and apply sufficient base fertilizer.

Frangipani Growing Methods

1. Soil: Frangipani is not demanding about soil. It grows best in loose soil rich in humus. When planting, you can slightly expose the roots when potting up. After planting frangipani, place it indoors in a shaded spot. After one week, give it weak light, and after another half month, it can be placed in a sunny spot.

2. Watering: Frangipani likes moisture and is also drought-tolerant, but it fears waterlogging. Therefore, watering should be moderate, following the principle of not watering when not dry, watering as soon as it is dry, watering thoroughly when watering, and never allowing waterlogging. In spring and autumn, water once every 1 to 2 days when the soil is dry. On sunny days in summer, water once every morning, and in the evening water again if the soil is dry. In the rainy season, be sure to pour out accumulated water in the pot to prevent root rot. In winter, water once every ten days to half a month, keeping the potting soil slightly moist but not dry.

3. Fertilizing: Frangipani likes fertilizer. When potting up or repotting and changing soil, it is advisable to add 20 grams to 30 grams of bone meal and 50 grams to 80 grams of superphosphate to the growing soil (because it likes to grow in calcareous soil, be sure to supplement calcium). From May to October, apply a light, thin decomposed organic fertilizer or nitrogen-phosphorus-potassium compound fertilizer once every 10 to 15 days. Avoid applying nitrogen fertilizer alone to prevent excessive vegetative growth. Do not fertilize in winter.

4. Light: Frangipani is a strongly sun-loving flower. The more sunlight it gets, the better it grows. Except for the 7 to 10 days of shade needed after potting up or repotting and changing soil, it should be placed in a sunny spot at all other times. Although it can also grow in a semi-shady environment, in a shaded environment the branches grow leggy, it blooms less, or it grows leaves without blooming.

Precautions for Growing Frangipani

1. Repot in time

Frangipani grows quickly, growing carefree every day. Usually it needs to be repotted once every spring, changing to a new pot according to the size of the plant. The potting soil can be mixed in the ratio of 4 parts garden soil, 4 parts horse manure soil and 2 parts river sand. Place an appropriate amount of base fertilizer in each pot. After repotting, water thoroughly, and move it to a sunny spot after one week.

2. Avoid freeze damage

Frangipani is not cold-tolerant. Try to keep the temperature above 5°C. When the temperature drops to 10°C, move it indoors promptly and place it in a sunny spot. Keep the indoor temperature at 10~15°C. Keeping it away from the radiation of household appliances can reduce leaf drop.

What to Do If Frangipani Drops Its Leaves

1. We need to water reasonably, choose a container with good drainage, and when watering, let the soil drink its fill. Do not let it go alternately dry and wet, and let the water flow out from the bottom; it must not accumulate.

2. You can appropriately change its potting soil for it. Of course, we should pay attention to this when we first plant the plant.

3. If pests and diseases appear, insecticides need to be used. There are specific pesticides for it on the market.

4. Frangipani has a great demand for light. If it does not get sunlight for a long time, it definitely will not do. Ordinary flowers cannot tolerate that, so let it bask in the sun often.

Frangipani is very easy to grow, but there are many things we need to pay attention to during the growing process, such as preventing it from freeze damage and repotting it in time, otherwise it cannot meet its growth needs and will be limited. On the other hand, leaf drop is a symptom it is prone to, so preventive work should be done in advance.
