Erecting fence - how to secure posts into the ground

[spada01]

Concreting in posts is a more involved job and more permanent so I'd like to use 30" steel spikes for erecting a 6 foot fence into soil. Does this sounds sensible and likely to stay upright?

no and no.

Apart from the question of how long they might last it's surprisingly difficult to drive these spikes in without them drifting off to one side or twisting as they reach stones etc. Fine for quick repairs (IMHO) but NBG for fencing.

Dig down 18/20 inches, then 'Postcrete' them in. Should be good for 15 years!
