How to care for gardenias in summer to make them grow more vigorously
Keeping them outdoors and getting too much rain can cause waterlogging in the pot, leading to yellowing leaves. The poor breathability and history of the soil can easily cause waterlogging in the pot, which can result in yellowing leaves. Moreover, excessive rain can make the soil easily turn alkaline. Alkaline soil can cause problems for the growth of gardenias, especially at the bottom, where yellowing leaves are most common.
This pot of gardenias, when kept outdoors for maintenance, is currently experiencing yellowing leaves. What are the causes?
1. Getting drenched by rain
Keeping them outdoors and getting too much rain causes waterlogging in the pot, leading to yellowing leaves.
2. Soil
The poor breathability and history of the soil can easily cause waterlogging in the pot, leading to yellowing leaves. Also, excessive rain can make the soil easily turn alkaline. Alkaline soil can cause problems for the growth of gardenias, especially at the bottom, where yellowing leaves are most common.
So, how can we improve these issues? If we want to improve yellowing leaves, we should start with the soil. For example, these nutrient-rich potting soils usually don't contain granular sand. When repotting, it's best to add a little ceramsite to the soil, as it has strong water permeability and won't cause waterlogging in the pot. Just add it in moderation.
To improve the alkalinity of the soil, using ferrous sulfate to water the plants can adjust the soil's pH level and promote photosynthesis to prevent leaf yellowing. After mixing 500 milliliters of clear water with one gram of ferrous sulfate, water it directly. Use it once every 15 days. If we persist in using it, we can effectively improve the soil's alkalinity, making it slowly turn into acidity, like this gardenia.
The above are some tips on how to care for gardenias in summer to make them grow more vigorously, hoping to bring help to your life!
