What causes the frangipani (plumeria) to drop its leaves?
Frangipani, also called egg-yolk flower, large-season flower, etc., is an ornamental plant suitable for planting in courtyards and on lawns. It can also be grown as a potted plant at home, and it is very popular with many people. Nowadays, very many people grow and cultivate frangipani on a large scale, and during care, frangipani often shows the phenomenon of dropping its leaves. So what is going on when frangipani drops its leaves? Below, the editor will briefly introduce it to everyone, let's take a look!
1. Unsuitable light
Light is very important for the growth of frangipani. Frangipani has relatively strict requirements for light; it can neither grow in a dark environment for a long time, nor receive overly strong light. If the light is too weak, it will reduce the photosynthesis of frangipani and decrease nutrient accumulation, while if it is too strong, it will cause leaf scorch and so on, and both easily cause frangipani to drop its leaves. So while keeping sufficient light, we must pay attention to controlling the light duration and intensity well. During the vigorous growth period, maintain about 7 hours of light, in summer do a good job of shading, and in winter appropriately supplement light artificially.
2. Improper soil
Soil is also very important for the growth of frangipani. Frangipani is suitable for growing in soft soil with strong permeability. If the soil is compacted and has poor drainage and irrigation capacity, then the impact on the growth of frangipani is very great. Soil compaction will inhibit the respiration of frangipani's roots, affect the absorption of nutrients and water, and so on, thereby causing the phenomenon of leaf drop. Therefore, in planting, we must pay attention to managing the soil well. Keep the roots breathing normally and drainage and irrigation normal. If it is grown in a flower pot, then repot once a year to ensure normal growth of frangipani and reduce phenomena such as leaf drop and yellow leaves.
3. Temperature reasons
Unsuitable temperature is also a main reason causing frangipani to drop its leaves. Frangipani likes to grow in a relatively warm environment, and its tolerance to high temperatures and cold is relatively poor. Temperatures that are too high or too low are very unfavorable to the growth of frangipani, and the most suitable growth temperature for frangipani is around 22-25 degrees. So after entering the hot summer, do a good job of cooling, spray water appropriately on the plant leaves, maintain humidity and lower the temperature. Similarly, in the low-temperature winter, do a good job of insulation to prevent excessively low temperatures from causing frost damage to frangipani and leaf drop.
4. Improper fertilisation
When planting frangipani, fertilisation work is essential. And many people, when fertilising, very easily cause frangipani to show the phenomenon of leaf drop because of improper fertilisation. Among these, too much fertiliser and too high concentration are the most common, very easily causing fertiliser damage to frangipani, causing root rot and leaf drop. Therefore, we must pay attention to rational fertilisation, do not apply too much fertiliser, and appropriately apply some thin liquid fertiliser each month to prevent fertiliser damage. After entering winter, because the temperature is relatively low, frangipani gradually goes dormant, and at this time fertiliser can be appropriately reduced, or fertilisation can be stopped.
The above is a brief introduction to what is going on when frangipani drops its leaves. That is all for today's introduction. This article is for reference only, and I hope it can help everyone!
