To feed roses in the fall, you need to dissolve 50 g of superphosphate in 1 liter of hot water, add 10 liters of water and generously spray the leaves of the plants.
It is also useful to spray roses with wood ash. For foliar feeding, you need to dissolve 200 g of ash in 10 liters of water and leave for four hours.
It is best to spray in cloudy weather or in the evening. If you spray plants during the day, when the sun is especially active, this can lead to leaf burns. And spraying after sunset can contribute to the development of fungal diseases, since the moisture does not have time to evaporate.
