Interesting you mentioned clay soil—same issue at my place, and it’s a pain. Did you notice any problems with roots getting into the perforated pipe later on? I’ve heard that can be a thing, especially if you plant over the drain.
Yeah, clay soil really complicates things. When I put in my French drain, I was worried about roots too. From what I read, it’s a bigger issue if you plant stuff like willows or certain shrubs right over the pipe. I tried to keep a buffer zone—just grass above mine—and so far, no root blockages. Lining the trench with landscape fabric before backfilling seemed to help as well. It’s not foolproof, but it might slow down roots trying to get in.
I hear you on the clay—my 1920s place has the same stubborn soil. When I put in a drain, I skipped planting anything deep-rooted nearby, but I did get lazy and let some ivy creep over. Regret that now... roots everywhere. Landscape fabric helped a bit, but honestly, keeping it clear above is what’s saved me the most hassle.
Ivy’s the worst for that—once it gets a foothold, it’s like a secret underground network. I tried to make a little “green wall” by my patio and ended up battling roots for years. Have you ever tried using gravel or river rock around your drains? I’ve seen it look surprisingly nice, and it seems to help with runoff, but I wonder if it’d just sink into clay over time...

Gravel and river rock can look awesome, but yeah, clay is a whole different beast. I tried a similar thing by my side yard—looked great for a while, but after a couple of heavy rains, the rocks started to disappear like they were being swallowed. If you want to give it a shot, here’s what worked for me: lay down a thick layer of landscape fabric first, then add your gravel or river rock on top. It helps keep the rocks from sinking and slows down weeds (ivy included...sneaky stuff). Not a perfect fix, but it definitely buys you some time before things get messy again.
