I should tell a bobcat is required if you wanna do the whole front/back yard OR just spot-excavation (dig a bigger and deeper than normal hole, dump the old dirt and back fill w/ good topsoil when you want to plant a new tree) if you gonna do the job yourself.

康版主,还记得我问过您移植樱桃树的帖子吗?您说的是秋后落叶移植。结果这两年我就等啊等,它们的叶子在下雪了以后也不落呀,而且地都冻了也没见落几个叶。现在估计是移植成活的希望不大了是吗?现在已经长得大概一米二左右了。
