发帖数: 125 | 1 去年冬天雨雪太多，前院草坪沉降出了一个4平方米左右2-4inch深的大坑.准备今年入
冬把它填起来，请教该怎么填？
全部用黑土填太费了，目前打算先用黄土填底下，上面1 inch填卖的普通黑土，最上面
再上一层top soil，不知道可行不？
另外，填土的时候，怎么让土生得牢一点？要不要先把原来的草皮铲掉，把土弄松再填
？要不要把土夯实？还是把土堆在上面等它自然沉降一段时间再补填，如此反复？
还有，什么时候补草籽好？是今天冬天填好就补上，还是明年开春再补？如果冬天补草
籽要不要勤浇水？北方，怕浇水被冻上。完全没经验，请各位大拿赐教 |

你这个要考虑排水问题，最好是有DRAIN流到
下水道去，否则以后还会积水。填坑，一般是
先把草皮挖出来，一块一块的，填TOP SOIL，
不要黑土，填平累实，然后把草皮放回去 |

发帖数: 125 | 3 我也觉得沉这么多很诡异。这片地还是在坡上不会积水的地方。去年雪太大太多，冬天
又长，等雪一化完就发现出了一大坑。
请问一定要全部用topsoil填吗？用黄土填行不行？我们附近修房子，黄土不要钱随便
拉，想着能省一点是一点 |

发帖数: 837 | 4 A healthy lawn needs 4-6" of good topsoil (not subsoil like the yellow one).
If you want to save money and have the extra time and energy, you can try
this: Say the current hole is 5" deep, so you cut the grass (like sod),
water it and save it aside. The grass is probably 2", so the hole is about
7" deep. You dig 5" down and those soil should be the old topsoil you can
reuse later. Now the hole is about 12" deep. You fill it with about 5.5"
yellow soil. Jump on it or compact it, but don't overdo it. Now the hole
is 6.5" deep. You fill back the 5" topsoil you excavated. Now the hole is
1.5" deep. You put the grass/sod back. It is about 0.5" above ground which
should settle back to level in the future. Water that area daily for a
couple of weeks.
If this all sounds too much work, just bite the bullet, cut the grass, fill
all with new topsoil, put the grass back, and water.
You can still stick with your original plan, but don't expect the grass in
that area would grow as well as in other places for a few years. |

再把草皮盖上去，差不多就行了。 |

4袋TOP SOIL根本不行。我家草坪靠房子一侧有少许沉降，也就10米长20厘米宽的一条
。我买了10袋TOP SOIL填了，当时还搞得高一些的一个小斜坡以利排水。结果过去一年
，又塌下去了。不知道是TOP SOIL流失了还是压塌了。

发帖数: 125 | 13 算了还是不搞黄土了，太费劲。直接买一车top soil来填算了。草皮挖出来再放回去还
能活不？这事适合冬天搞还是春天搞啊？我们这儿已经下雪了，现在弄会不会养不活草
？ |

发帖数: 837 | 14 To be safe, I'd do it next spring, after grasses have greened up.
However, if it looks ugly and you can't stand it over the winter, you can
try to do it now. Cut a bit more (i.e. preserve the roots of the grass as
much as possible instead of cutting half way through the roots), and water
for a few days to a week (if no rain) after putting the grass back. There
is a chance that the grass might die over the winter, but it isn't 100% (i.e
. they might turn out OK too, but I don't know the actual probability of
dying.) If they do die, just seed it over next spring. |
