What are the symptoms of over-fertilization in roses?
Many rose enthusiasts often suffer from improper fertilization, causing the roses to show symptoms of over-fertilization. So, what are the symptoms of over-fertilization in roses? The details are as follows:
What symptoms does over-fertilization in roses have?
When the leaves of roses become significantly thicker and not bright green but dark green, this is a manifestation of overgrowth. Many enthusiasts like the shiny dark green leaves of roses, but in fact, this is a sign of overgrowth. However, this condition is merely overgrowth and not yet severe, not causing significant fertilizer damage.
If the leaves of roses have turned yellow or the edges of the old leaves have turned brown, it indicates that the roses have been over-fertilized and have already caused considerable fertilizer damage. This is especially true in spring when the young buds just start to sprout. If fertilizer damage occurs, the new buds will also show signs of withering.
If the old leaves of roses turn yellow, blacken, and fall off, and the young leaves become wrinkled, it indicates that the roses have been over-fertilized and have already shown severe symptoms of fertilizer damage. In such cases, even the newly grown leaves will appear black and wilted, and the subsequent symptoms are that the main stem will start to blacken from the root, then wither, and finally, the rose plant will die.
How to fertilize roses correctly
Roses grow very vigorously in spring, so fertilization should be sufficient during this stage, but attention should be paid to balanced nutrition. The fertilizing frequency is generally maintained at about every 10 days. Also, before roses bloom, it is necessary to apply a light fertilizer at the appropriate time to provide more abundant nutrition for the roses.
When the temperature is low in winter, the plant will enter a dormant period, and only base fertilizer needs to be applied during this time. These fertilizers are to provide nutrition for the roses' growth in the second year.
