It is important to remember that roses need quality care at the end of the season.
This means that pruning, watering and treatment against potential diseases and pests are necessary.
However, do not forget about feeding: its importance is difficult to overestimate.
There are many options for potassium sources. For example, you can take one large spoon of potassium monophosphate per bucket of water. The same amount of potassium sulfate is also used.
Wood ash is also used as a source of potassium. For the same volume of water, take 200 grams of the product.
Potassium is usually applied twice. The first time, the top dressing occurs at the beginning of autumn, and the second time, about 20 days later.
This fertilizer is necessary for roses to survive the winter and withstand cold weather. It is customary to carry out this feeding closer to the end of autumn.
It is best to take forty grams of fertilizer per bucket of water. One bush can take up to five liters of the composition.
