As in the case of azaleas, tree rhododendrons are also acidophilic plants, which suffer when irrigated with calcareous water in summer. The root system, growing on the surface and susceptible to damage by soil turning and removal of organic matter during park cleaning, requires respectful management. For this reason, they are also fertilized with soil improvers, such as mature manure, which provides nutrients and gives a better structure to the growing medium.
