It is quite normal for you to ask yourself why do Vinca leaves turn yellow? You will see that lots of plants can show yellowing of leaves. In some cases, the color of the leaves will last for a few years. However, this is normal especially in the case of some flowering plants. The reason for this is quite simple and it is called photosynthesis.
The process of photosynthesis means that plants use the energy from the sun to produce food. During the day, they consume light from the sun and so their leaves become dark yellow. At night, they use the light from the sun to synthesize food and thus their leaves become bright green.
In autumn, when the day becomes darker, photosynthesis stops. At that time, the plants stop using the energy from the sun and so they start using chlorophyll. Chlorophyll is a colorless pigment that is found in stems, leaves and roots. When the sun no longer provides enough light, plants must use the stored energy in the form of carbohydrates from starch and sugars. As they do, the yellow color of these plants turn yellow and fall off.
The question is, why do Vinca leaves turn yellow? This yellowing happens due to the reduced production of chlorophyll and the reduced use of sugars. The reduced production of chlorophyll is caused by the yellowing of the photoresponders.
Most plants that turn yellow are stressed. Stress results in the reduced usage of nutrients and therefore results in the yellowing of the leaves. Yellowing can also be caused by overfeeding or malnutrition. In cases like this, the yellowing will stop once you reduce the stress.
We have been told that eating leafy vegetables such as spinach can help with our health. But why do vinca leaves yellow? The reason is that the leafy greens contain lots of chlorophyll. If we eat more green leafy vegetables, more chlorophyll gets extracted from the leaves thus, more sugars and starch is used up. The more sugar and starch is used up, the more chlorophyll gets depleted hence, the yellowing occurs. You should try to limit your daily intake of leafy green vegetables if you want to maintain the color of your vinca leafy vegetable.
Another reason why do vinca leaves turn yellow is sunlight. Sunlight gradually depletes the chlorophyll so that less energy is available for conversion to sugars and starch. This can cause a drop in water content and eventually the roots will die. This is why do vinca leaves turn yellow when exposed to the sun. If you live in a region where there are strong sunlight hours, it is advisable to shade your vinca garden during those hours.
Another environmental cause for the appearance of the leaves and stems is poor drainage. When we water our gardens, the water is flushed away quickly with the rain. The result is leaves that look dry and withered because there is not enough water for plant growth. To prevent this from happening, create a shallow layer of soil below the surface of the soil. To encourage drainage and discourage turning yellow, cover your plants during cold weather or whenever it is raining.
A fungus called dermatophytes causes turn yellowing of leaves. This fungi attacks rose plants at the base of the leaf where the leafstalk joins the stem. To control the fungi from turning the leaves yellow, use organic and inorganic fungicides. You can spray the entire plant or just the areas affected by the fungi.
Vinca hyssop is a disease that causes the plant to change color. It generally begins in late summer and continues through the fall. The appearance is often similar to that of a yellowish scarlet rose. There are a variety of fungicides to treat this disease: buy brand names or use products made from vinegar.
In conclusion, I have given you some basic information on why do vinca leaves turn yellow. Next time you go to your garden, look for other varieties that could be turning colors or you could just buy them because they are appealing to you. They are beautiful plants with small flowers that make a difference in your garden or even your yard. I hope you find them attractive.
