Unpopular opinion: that $180 string light pole kit from the hardware store was the worst money I put into my yard
I want to save somebody else the headache here. Two summers ago I bought one of those metal pole kits for hanging string lights over my patio in Fresno, paid about $180 for two poles and the little stakes, and they were tipped over within 3 weeks. The stakes are like 8 inches long and the poles wobble bad once the ground dries out, so my lights were sagging and dragging on the ground by the 4th of July party. I ended up pulling them out and sinking three 10 foot 4x4s about 2 feet deep in concrete instead, which cost me maybe $60 total and hasn't moved once. The worst part is I had to patch the grass where the old stakes ripped through it. If you're hanging lights between posts, skip the kit and just dig a real hole. Has anyone found a cheap anchor that actually holds a pole straight through a dry summer?
Sinking those 4x4s 2 feet deep was the smart move, but if you want to skip the concrete next time, drive a 3 foot piece of rebar next to each post and strap the pole to it, that setup has held my neighbor's lights straight through two Fresno summers.
