Each plant is characterized by certain growth needs, however, when it comes to acidophilic plants we can generalize by stating that this type of plants prefer limited exposure to the sun with crops in shady or partial shade areas. These are perennials, perfect for flower lovers: for cultivation the soil must be constantly humid but free from water stagnation so care must be taken to water them little and often. Always to avoid water stagnation, if you cultivate theacidophilic plants in pots, prepare a draining layer.

Be careful to choose the species that best suit the characteristics of your garden! For example, if you like cultivate camellia(acidophilic plant par excellence) but you have no shaded areas, rather than choosing the most popularCamellia japonica, choose Camellia sasanqua or one of its varieties. Camellia sasanqua is an acidophilic that tolerates the sun and summer heat better, among its varieties there are those that begin to bloom during the Christmas period until February. The varieties of Camellia japonica start flowering in October and finish flowering between December and January.

For acidophilic plants grown in pots in Northern Italy or in mountainous areas with a cold climate, we recommend lining the pot externally with polystyrene sheets or more natural insulating materials such as cardboard and straw. The ideal would be to be able to transfer the pots to a veranda or a sheltered area.
