Periwinkle gets more beautiful the more it's sunned, blooms in all four seasons - what to do when the leaves turn yellow?

Five-petal plum, also called Tian Tian Kai, with the scientific name Catharanthus roseus (Madagascar periwinkle), comes in a wide range of colors, is very easy to grow into a full pot, with a single pot able to bloom hundreds of flowers, has a very long flowering period, is very pleasing to look at, and is also very easy to care for. When all the various colors are put together, doesn't it just dazzle the eyes? Some friends say that the periwinkle they grow at home just loves to have yellow leaves - what's going on with that? Let's analyze this problem. When it comes to yellow leaves on five-petal plum, it's no more than these few reasons

1. Compacted potting soil. Five-petal plum doesn't have high soil requirements, and many friends can grow it well even with garden soil, but if the soil is compacted and not breathable, the roots can't spread out fully and can only absorb limited nutrients, and this first shows up as the problem of yellow leaves

2. Lack of water. Five-petal plum grows very fast and blooms a lot, so this requires us to give it a sufficient supply of water and fertilizer. Once it lacks water, it will cause the leaves at the bottom to turn yellow and fall off. You need to replenish water for it in time and keep the potting soil slightly moist

3. Overwatering. Overwatering means the roots can't breathe and are prone to rot, and this first shows up as the problem of yellow leaves

4. Lack of fertilizer. During the growing period of five-petal plum, you need to frequently supplement it with fertilizer water to let it grow vigorously, because it grows flowers and branches at the same time, so you need to supplement it with a multi-element fertilizer, once or twice a month is enough, which can make it bloom abundantly with large flowers

Five-petal plum grows relatively fast. To prevent the plant from growing too tall and leggy and becoming hard to manage, you need to prune and pinch it frequently. Once it grows to the height you like, you should pinch off the top

Let it branch out more side branches. When the side branches grow to a certain length, you can pinch the tops again, so it branches out even more side branches, and the side branches will all bloom, which can let it bloom into a flower ball. Prune off spent flowers in time, and it will keep blooming one round after another without stopping
