For the past few days, the weather has been overcast and rainy. The Jiangnan region has entered the rainy season mode. Some flower lovers have asked why Chinese roses turn yellow and wilt after being exposed to the rain for a few days.
Many flower lovers may think that too much rain causes this issue. However, there's nothing wrong with Chinese roses being exposed to rain. Think about the Chinese roses planted in the ground and those in outdoor pots. They are all getting rained on and growing well.
Moreover, ample rain is also beneficial for the sprouting of Chinese roses. Therefore, we can often see that Chinese roses planted in the ground sprout many suckers during the rainy season.
So why do potted Chinese roses turn yellow and wilt after a few days of rain?
The most common reason for problems after Chinese roses are exposed to rain is that the accumulated water in the potting soil leads to root rot.
There are usually several reasons for water accumulation:
1. The potting soil does not have enough drainage.
Many flower lovers use coconut brick soil or general nutrient soil to grow Chinese roses. Both types of soil retain water very well. After being rained on for a long time, the soil does not dry easily, causing the roots to be闷 in a hot and humid environment, leading to root rot.
When growing Chinese roses, the soil is mixed by ourselves, with particles accounting for 1/3 of the total volume, ensuring good drainage and ventilation. Even in the rainy season, no water accumulation occurs.

2. The drainage holes in the pot are blocked.
3. Improper use of saucers.
Besides the issues of soil mixture and blocked pot drainage holes, sometimes our minor negligence can also cause Chinese rose pots to have root rot.
Many people like to use trays for indoor balcony cultivation. Since excess water flows out during watering, a tray is used to catch the water to prevent it from spreading everywhere.
However, if a tray is used for outdoor cultivation during prolonged rain, it can lead to poor drainage, with the tray always having water, and the potting soil cannot go through the wet-dry cycle. Therefore, after several days of continuous rain, there will be issues with yellow leaves and wilting during the rainy season.
You might ask, without a tray, Chinese roses are also constantly getting rained on and are wet, but there are no problems. Why is there a problem with a tray?
