Today, I would like to share with you about gardenias. Look at my pot of gardenias, they are doing quite well. I have previously shared with everyone how to care for them, and sterilization is the most important part.
Because during this period, we have entered autumn, and with various flowers to take care of, I neglected this pot of gardenias. I didn’t take care of the potting soil in time, which easily led to bacterial growth. There is a type of bacteria on the surface of the potting soil, which has caused mushrooms to grow. Let me show you these mushrooms; they are yellow.
If the mushrooms are white, it proves that there are a lot of beneficial bacteria in the potting soil. However, if they are yellow, it indicates that there are many bacteria in the potting soil, which will harm the growth of the plants. Therefore, we need to deal with it promptly by sterilizing the soil, or they will multiply even more.
So, what kind of sterilization is effective? The fungicides we usually use are carbendazim or mancozeb, both of which work very well. However, because the potting soil is too moist, these fungicides need to be diluted in water and watered into the soil to achieve good results.
The soil is too moist and not suitable for watering with diluted water. You can choose to use this small powder fungicide, pyrithione, because it is in granular form. You just need to sprinkle it into the potting soil, and it will dissolve quickly. Its efficacy lasts for forty days.
Then, we use it once every thirty days for better sterilization effect. We need to remove the mushrooms, loosen the surface of the potting soil, and it will dissolve quickly in the potting soil to sterilize. In the early autumn, when caring for various flowers, don’t forget to sterilize them.
