This was the second soil spear from brabantia, the first hit stones deep in the soil an decided to lean and even with using a piece of wood to protect the opening it didn't go in well, in fact i had to dig it out and start again with a new spear
This time with the hole already dug and using post quick dry cement mix, I was able to put it to vertical without any problem and I have a top notch item, perfectly vertical and fitting the drier like a glove.
If you don't know what the soil spear is going into, then I suggest you also dig the hole and use some fixing cement mix.
