In the first month of autumn, roses require specific micronutrients and nutrients. Without them, plants may not be able to withstand the upcoming adverse weather conditions, such as the expected significant drop in temperature in the coming months.
You can replenish the supply of these essential elements with mineral or organic fertilizers.
First Feeding Method
For those who prefer organic options, you can use a mixture of manure and wood ash.
To prepare the fertilizer, place one kilogram of manure in a bucket, fill it with water, and leave some space at the top. Then add one cup of wood ash. Let the mixture steep for a week.
Once the infusion is ready, dilute it with water at a ratio of 1 liter to 2 liters. For every square meter of soil, you need approximately a bucket of this mixture.
Second Feeding Method
If you prefer mineral fertilizers, you can use a mixture of superphosphate, potassium sulfate, and boric acid.
To prepare the fertilizer, take a bucket of almost full water and add 25 grams of superphosphate, 10 grams of potassium sulfate, and 3 grams of boric acid. Thoroughly mix everything to form a solution, and then use this solution to water the soil surrounding the roses.
Both of these feedings will help roses strengthen and prepare for the winter cold, increasing their chances of successfully surviving frost.
