Ileana, dove trovi il ph più idoneo per ciascuna pianta? Nei miei libri non è mai citato, anzi, al massimo e non sempre (anche quando sarebbe indispensabile) dicono : richiede terreno acido.
per capire: le quercifoglia e i rododendri (ammesso che siano, come immagino, la prima bisognosa di terreno POCO acido o neutro, il rododendro MOLTO acido) di quale ph avrebbero bisogno?
(sei una miniera informativa)..
