Rost® Sour – is a series of acidifying fertilizers for acid-loving plants, thatare intended for soil application and have an acidifying effect: lower pH of thesoil. The application of the fertilizer promotes the development of the root system,stimulates growth, increases plant immunity and makes it possible to growacid-loving plants on unsuitable for them neutral and slightly alkaline soils bygradual acidification of them. The fertilizer contains nutrients in the ratios that arebest for the development of certain acid-loving plant species.

Application:
for soil application onmany species of hydrangeas during the growing season
