根系发达程度决定水培成活率：绿萝、白掌、铜钱草等已长出白色水生根（区别于褐色土生根）的植株成活率>90%，购买时优先选择已完成水土转化、水生根长度≥3cm的成品

Unverified选购时看根系：水培绿萝应有粗壮白色气根≥3条，土培绿萝提盆感觉根系抓土紧实不松动，散土说明刚上盆存活率低79% similarUnverified土培转水培的植物成活率低，选购时确认是「水培苗」而非「洗根苗」——水培苗根系为白色透明水生根，洗根苗为黄褐色土生根，后者需15-30天诱导新根，易黑腐79% similarUnverified土培转水培需洗净根部泥土并剪除烂根，缓苗期2-4周内根系可能大量脱落，属正常现象；直接买水培苗成活率更高79% similarUnverified从土培直接转水培成活率低，土培根系（旱生根）无法直接适应水中环境，需先洗净根系、剪除老根、诱导新生水生根（约2-4周过渡），购买时应选择商家已水培适应的成品苗76% similarUnverified水培植物的"陆生根"与"水生根"结构不同：土培转水培时原有的陆生根会逐渐烂掉，需长出白嫩的水生根才算真正适应，此过程约需1-3周，期间烂根属正常应及时修剪而非丢弃75% similar
