What is the reason for the yellowing of the rose leaves from bottom to top
Roses are a common type of flower in our lives. So what happens when the leaves of roses turn yellow from bottom to top during their care? Let's find out today.
Reasons for the yellowing of rose leaves from bottom to top: Soil compaction
Roses prefer loose and breathable soil to grow better. If we do not change the soil for a long time when caring for roses, the soil may become compacted due to excessive absorption, which can lead to poor soil aeration. As a result, the roots of the roses cannot properly contact the air, causing the leaves to turn yellow from bottom to top.
Soil overly alkaline
In addition to the soil being loose and breathable, roses need to grow in slightly acidic soil. If the soil is too alkaline, the growth of roses will be affected, and the leaves will turn yellow from bottom to top. We can change the soil to an acidic one to allow the roses to grow normally. If the yellowing is not severe, we can add some ferrous sulfate to the water when watering, which can also change the soil pH.
Lack of nitrogen fertilizer
Roses love fertilizer and consume a lot of nutrients when flowering. Therefore, we need to fertilize frequently, usually every ten days or so during the growth period of roses. If the nutrients are insufficient, the leaves of roses will turn yellow from bottom to top. In this case, we can add more nitrogen fertilizer to the roses, which can make the leaves greener.
The above is the full content of why the leaves of roses turn yellow from bottom to top. Green plant enthusiasts can refer to this aspect.
