Rent an auger...save your back! Post hole digging sucks! My brother in law has one. Saved my ass when we moved our fence to create a parking pad in my back yard.
This is absolutely the best advice you will receive on such a topic SC. I did landscaping for 17 years. We did a lot of digging. The first 4 years we used post hole diggers, the last 13 we used an auger. I aged more in the first 4 years by far.
I have already looked into that, I am going to get a towable one so I dont have to wrassle the two person kind. Hopefully the ground thaws in a month or so lol
Two person kind? They aren't as bad as they look, they have one man augers that are more than sufficient, that you can throw in the back of a truck. They rent them for the day at Lowes and Home Depot for like $30, and I promise you using a one man auger will make your life easier than lugging around a big ass bulky one that you can't get into the right spot without moving it around a dozen times. The bigger augers are frustrating as hell to use, and they all have problems starting.
The only issues you will ever run into with a one man auger are tree roots. If you hook one, it turns the auger real quick, but there is a very sensitive stop bar that will hit your leg and stop the rotation so you don't hurt yourself. In 13 years of regular use, I hit maybe a half dozen roots, so it isn't a common problem. People make augers out to be far more difficult than they actually are.
Something like this is all you need......
