树桩盆景生长一段时期以后,根系布满盆土,纵横交错,以致吸收肥水能力减弱,同时盆土中的营养元素愈来愈少,对树桩生长不利,必须进行翻盆换土。翻盆宜在早春至清明这段时间进行,在秋天9月份亦可。根系生长迅速的树种,如石榴、三角枫等,每隔一至两年翻盆一次;生长较慢的树种,如松柏类,可隔三至四年翻盆一次。盆土的原料一般用腐叶土,可由山泥、园土与落叶 After a period of growth of the stump bonsai, the root system is covered with peat soils that crisscross, so that the ability to absorb fertilizer and water is weakened. At the same time, the nutrient elements in the basin are less and less favorable to the growth of stumps. Turn basin should be carried out in the early spring until Ching Ming period, also in autumn in September. Tree species with rapid root growth, such as pomegranate, maple, etc., turn the basin every one to two years. Slowly growing species, such as the coniferous and cypress species, can be turned up every three to four years. Basin soil raw materials commonly used leaf mold, by the mud, garden soil and leaves
