What causes a Dipladenia not to bloom
Dipladenia is an evergreen climbing plant, also known as the double-fragrance vine, and has only gradually appeared on the flower market in the past two years. It is very strong at climbing, and as long as you set up a trellis for it, it can grow into whatever shape you want. But some friends have found while growing it that it does not bloom; what causes this? Let's take a look together.
1. Not repotting for a long time
There are many reasons that cause Dipladenia not to bloom, so you need to identify the cause and treat the root problem accordingly. First, the reason Dipladenia does not bloom may be that it has not been repotted for a long time. Generally, repot it in spring, and choose a fertile, loose, breathable sandy soil with good drainage. During care, you should also loosen the soil at intervals, which can restore good looseness and breathability to the soil, and only in this way can the plant be ensured to bloom normally.
2. Insufficient light
Light plays an extremely important role in the growth and development of plants. If Dipladenia is kept in a dark environment for a long time, it cannot carry out photosynthesis normally, and this will cause it to be unable to bloom normally. So during cultivation you must give it sufficient light conditions, but note that strong direct sunlight is not suitable, to avoid causing scorch. In addition, temperature is also quite important; if it is in a high-temperature environment for a long time, this will also affect its blooming.
3. Overwatering
During the growing period of Dipladenia, if overwatering causes water to accumulate around the roots and rot them, this will also affect the overall quality of the plant. Not blooming may be the mild outcome; in severe cases it can cause the whole plant to die. So when watering, you must be reasonable and just keep the soil moist. In hot seasons you can appropriately increase the watering frequency, and you can also spray water mist around it to increase air humidity.
