"They mentioned unexpected issues like weeds taking over and drainage problems during heavy rains."
Interesting, hadn't thought about weeds being an issue on green roofs...makes sense though. Wonder if that's more common with certain plant types or just a general maintenance thing? Also curious if anyone's tried partial green roofing—like just a small section or garden patch—to balance benefits and upkeep. Might be a good compromise?
Weeds definitely pop up more with certain plants—especially if you're using sedums or grasses, since they can leave gaps for weeds to sneak in. Have you thought about using groundcovers that spread quickly and densely? I've seen partial green roofs work pretty well, actually. A friend of mine did just a small herb garden patch on his roof, and it's been manageable so far...plus, fresh herbs right upstairs is a nice bonus. Might be worth a shot if you're worried about upkeep.
Yeah, herbs are a solid choice. I put thyme and oregano on a small roof patch a couple years back, and they've filled in nicely—barely any weeds now. Plus, smells great when I'm up there cleaning gutters...unexpected perk, haha.
Haha, gotta love those surprise perks. Thyme and oregano on the roof—now that's creative. I've seen folks try sedum or moss, but herbs sound way better. Bet it makes gutter cleaning a bit less of a chore, huh?
Honestly, anything that keeps weeds down and smells good is a win in my book. I once had a client who planted mint around the downspouts...smelled amazing, but man, that stuff took over fast. Had to trim it back every season or it'd climb right into the gutters. Lesson learned: herbs good, mint invasion bad.
Sounds like you've got a solid system going though. Keep it up!
"Honestly, anything that keeps weeds down and smells good is a win in my book."
Fair point, but I'd be cautious about herbs on roofs. They might smell nice, but roots can sneak into tiny cracks and cause leaks later. Maybe stick to pots or raised beds instead? Just my two cents...
