What to do about yellow leaves when growing flowers? It turns out these 3 details were overlooked

Growing some flowers and plants is a daily pleasure too. Watering and fertilizing, keeping the potted flowers looking beautiful, and beautifying the home environment as well - it really kills two birds with one stone. But in the process of growing flowers, yellow leaves and root rot are hard to avoid. Yellowing leaves in particular are a problem that many potted plants are prone to. In the end, it still comes down to overlooking a few details of flower care.
1. Placing the flowers in a spot with poor ventilation
Especially in the stuffy heat of summer, what potted flowers need most is a well-ventilated environment. Even if the pot is placed on a balcony, without ventilation it will still cause yellow leaves. Why? Because a well-ventilated environment can continuously supply the leaves with abundant carbon dioxide, which helps them carry out photosynthesis. When photosynthesis is hindered, the leaves will certainly turn yellow and dry up.
2. Watering too frequently, so the roots cannot breathe and rot
Do not assume that you have to water as soon as the potting soil looks dry. For many flower pots, the surface being dry does not mean the soil inside the pot is dry. Especially in the hot summer weather, a dry surface on the potting soil is mostly an "illusion." You must check whether the pot has dried out completely; otherwise, watering too often will lead to excessive water accumulation and insufficient oxygen, affecting the respiration of root cells and causing the cells to rupture and the roots to rot. Once the roots of a potted flower have rotted, the leaves start turning yellow from the base and gradually spread to the whole plant.
3. Fertilizing during the flowers' dormant period, causing "fertilizer-induced yellowing"
Many flowers are in a dormant state during the high-temperature summer season, such as Christmas cactus (Schlumbergera) and similar plants. Being in a dormant period means they grow slowly, so at this time you absolutely must not fertilize, or only fertilize sparingly. Otherwise, excessive nutrients will cause "fertilizer yellowing." This situation is fairly common, because most flower lovers think potted plants should be fertilized all year round, or else they will not grow well. Be sure to remember this next time: flowers in their dormant period must not be fertilized.
That is all for the knowledge about yellow leaves during flower growing. Thank you for reading!
