Euonymus sp. shohin bonsai in glazed pot. In many cases, Euonymus are beloved shrubs for their bright red foliage color in autumn. Its care is not among the hard-to-grow shrubs. In this shohin size category, in the warmer season, extra care must be taken to ensure the continuous moisture content of the planting medium. This is also true for Euonymus, as we must strive to keep its soil always moist. When dry, its leaves start to droop and lose their firmness. It is recommended to keep it in a bright place protected from direct sunlight. In hot summer times, its leaves can burn. We treat it as a coldhouse plant during the winter. Winterize in a frost-free, sheltered place where the temperature is between 2-10 degrees. Constantly fertilizing promotes optimal development, so from spring to autumn it is worth using organic fertilizers, such as Biogold, BonsaiMaster or Bio-green liquid fertilizer.
