Reasons for Yellow Leaves After Fertilizing Roses
Roses have full and bright blooms and are a very popular type of potted plant for home. Recently, some rose enthusiasts have reported that after fertilizing their roses, yellow leaves appeared. So, what's the reason for this?
1. Unripe Fertilizer
Many enthusiasts like to make their own fertilizers, but there are also certain risks involved. If unripe fertilizer that has not fully decomposed is used, it can easily cause root burn in roses, leading to yellowing of the leaves. Therefore, homemade fertilizers must be fully decomposed before being used for gardening.
2. Concentrated Fertilizer
Fertilizer concentration is not the higher the better. When the fertilizer concentration is too high, it can also cause root burn in roses. Therefore, when fertilizing in spring, it's important to follow the principle of applying thin fertilizers frequently. If you find it difficult to control the amount of granular fertilizer, you can also use organic liquid fertilizers for roses, diluting them with water at a ratio of 500 times and then watering the roses directly.
3. Incorrect Fertilizer
Different growth stages require different types of fertilizers. During the growth stage of roses, some nitrogen and potassium fertilizers need to be applied to supplement nutrients, while during the blooming stage, phosphorus fertilizers need to be applied to promote flowering. Therefore, when fertilizing, it's important to apply the correct type of fertilizer for different stages.
