I’m sure. Not too many places in New England where you can drill without hitting large rocks. I’ve tried the hand hole diggers and they’re an exercise in futility.
Get a hole digger and bury that thing. Far too many diy’ers don’t go more than 12-18” and the posts end up getting pulled out of the ground to to freeze/thaw cycles and the heaving of the ground. You bury that thing below the frost line and that ain’t going anywhere. It could not hurt to do the flex seal or some sort of bitithene type membrane around the part of the post that is buried. May be a bit costlier but would extend the life of the post if covered properly.
And we have a nasty outbreak of Hairy Bittercress around the yard. This shit sprouts up in February and is dropping seeds before you even know you have it. The seed pods explode at the slightest touch when they are mature and the cycle begins all over. Looks like this.
Ok folks, I got a tree out back that makes these “flowers”, early Spring, every year. Flower is about 1” long. What is the tree? It’s currently about 15’ tall and has grown from a seed that must have blown there.
Geez, my lawn has never looked like that. No time to work on it myself and not enough disposable income to get an irrigation system and have someone come to do all the maintenance.
