1. What to do when the leaves of Tabernaemontana divaricata turn yellow: find the cause
If you want to know what to do when the leaves of Tabernaemontana divaricata turn yellow, first we need to know what causes this phenomenon. Only after knowing the cause can we solve the problem accordingly. Things like insufficient light and improper watering are both causes of this phenomenon. As for exactly how to solve it, there is a detailed introduction below. Let us take a look.
2. Causes of yellowing leaves in Tabernaemontana divaricata (with solutions)
1. Temperature too low
During the growth process of Tabernaemontana divaricata, its requirements for environmental temperature are very high. This plant is relatively intolerant of cold. If we do not do a good job of controlling the temperature during cultivation, causing the environmental temperature to be too low, it is very easy to cause the leaves of Tabernaemontana divaricata to turn yellow. Moreover, if the temperature is too low, it is also easy to freeze and even kill the plant.
Solution: During the growth process of Tabernaemontana divaricata, it is very important to let it grow at a comfortable environmental temperature. Its suitable temperature is above 10°C. If it is below this temperature, the leaves of Tabernaemontana divaricata will turn yellow. If it is below 0°C, the branches will suffer frost damage. Therefore, when cultivating it, we must do a good job of controlling the temperature.
2. Improper fertilizing
Fertilizer is one of the main nutrients during the growth process of Tabernaemontana divaricata. If we apply too little fertilizer or the fertilizer concentration is too high, it will cause the leaves of Tabernaemontana divaricata to turn yellow. If too little fertilizer is applied, it will wither and turn yellow due to insufficient nutrients. If the fertilizer concentration is too high, it will burn the plant and cause yellowing.
Solution: During the growth process of Tabernaemontana divaricata, its demand for fertilizer is very high. Especially after entering the growth period, its demand for water is very high. Basically, it needs to be fertilized once every 7-10 days, so that its leaves can grow large. However, when fertilizing, the fertilizer concentration must not be too high. Before application, it must first be diluted with water. If the concentration is too high, it is very easy to burn the plant.
3. Insufficient water
During the process of cultivating Tabernaemontana divaricata, especially after it enters the growth period, its demand for water is very high. Especially in summer, if it is not watered for one day, its leaves will wilt and turn yellow. If there is long-term water shortage, it can also cause the plant to wither and die.
Solution: Tabernaemontana divaricata likes to grow in a warm and humid environment, so during our daily care of it, we should keep the soil moist and not wait until the potting soil is completely dry before watering. In summer, when the weather is relatively hot, we basically need to water every day, and we should also frequently spray water around it to increase air humidity.
4. Insufficient light
Tabernaemontana divaricata is a light-loving plant. If the light is not sufficient enough, its leaves will gradually become dull and lose their green color, thus gradually showing yellowing. Therefore, for it, light is very important.
Solution: If the yellowing leaves of Tabernaemontana divaricata are caused by insufficient light, we had better not immediately move it outdoors for direct sun exposure. Instead, place it in a spot with scattered sunlight for care. After it recovers, let it receive sufficient light.
5. Pests and diseases
During the process of cultivating Tabernaemontana divaricata, if cultivation is improper, problems such as pests and diseases are very likely to appear. Such problems are extremely harmful to the plant. They will not only cause the leaves of Tabernaemontana divaricata to turn yellow, but in severe cases will also cause the plant to wither and die.
Solution: If problems such as pests and diseases appear on Tabernaemontana divaricata, we must deal with them in time.
