Gravel definitely makes a difference, especially if you go wider than you think you need. I did something similar last summer—dug a trench almost two feet across and filled it with crushed stone, then dropped in perforated pipe. Didn’t bother with fabric after seeing it gum up in one season. The gravel’s been enough to keep the clay from clogging things, at least so far.
I’ve tried corrugated and smooth pipe, and honestly, both get root issues eventually. Seems like if there’s any moisture down there, the roots will find it no matter what you do. The only real win I found was making sure the water had somewhere to go—if your outlet is lower than the rest of the yard, you’re halfway there.
Moving all that rock is a pain, though. My back still remembers it... If I ever do it again, I might just rent a small loader instead of trying to shovel it all by hand.
I hear you on the back pain—moving gravel is no joke. One thing I’d add for anyone tackling this: watch your trench depth and slope. I made the mistake of not double-checking my grade with a level, and water pooled in the middle until I fixed it. Also, if you’re worried about roots, I’ve seen folks wrap the pipe in a sock filter instead of landscape fabric. It’s not perfect, but it seems to slow down root intrusion a bit longer. Loader rental is definitely worth it if you’re moving more than a couple yards of stone... saves your spine and a lot of time.
I get the appeal of sock filters, but honestly, I’ve seen roots punch right through those over time—especially with aggressive trees nearby. If you’re in a spot with a lot of roots, rigid PVC with glued joints is way less hassle long-term. Corrugated’s easier to lay, sure, but it’s a pain to clean out if it ever clogs. Loader rental’s a lifesaver, though... my back still remembers the last time I tried to do it all by hand.
I hear you about roots and sock filters. My uncle swore by corrugated with the fabric, but a few years in, we had to dig up half his side yard because maple roots just ate right through it. PVC’s a pain to cut and glue, but once it’s in, you don’t really worry about it much. Loader rental is worth every penny—last time I tried shoveling out a trench, my arms felt like noodles for days. I guess it depends on how much you wanna gamble with those roots...
PVC is definitely a hassle up front, but I’ve found it’s worth the extra effort, especially if you’re dealing with aggressive roots. Corrugated’s just too easy for roots to invade, even with the sock—been there, dug that up. Loader rental is a game changer, no shame in skipping the shovel when you can. It’s a pain now, but you’ll thank yourself in five years when you’re not redoing the whole thing.
