Hellenia plants prefer well-drained, fertile soil and a sunny or partially shaded location. Start planting by first preparing the soil - remove weeds, incorporate organic matter, and if necessary, adjust the soil's pH. Next, dig a hole twice the size of the hellenia's root ball, place your plant, and fill in with soil. Water thoroughly after planting and maintain regular watering, particularly in drier periods. Being a diverse genus, different species may have unique requirements; hence, researching individual species is beneficial.
