How high was your mower set? Are you only seeding clover, or is it a mix? If you're only seeding one type of clover, you'll have a monoculture lawn which will be more susceptible to pests and stress. Even Farmer's Almanac says mixing the clover with a low grass is a good idea if it's foot traffic area, but I can't speak from experience to that.phil wrote: I've been trying to get clover growing rather than grass. . It's taking but this year I opted to not cut it and just let it try to fill in because last year I mowed my clover and it got very sad.
Speaking of mixes, did you look into Roman chamomile at all? It's a lower growing perennial chamomile and has little flowers. It's something in my list of possibles to mix into our clover we've been encouraging to spread. It's sometimes also called Russian chamomile or English. The German chamomile (reseeding annual) grows much higher with bigger flowers. Our front lawn faces north, and gets at least partial day shade depending from the house. That works well for chamomile. It grows in full sun, but it has an easier time in partial. It's also drought tolerant.
How heavy in clay is your soil mix? I've seen it recommended to mix clover seed with sand to help it along for clay heavy soils. How sunny is the lawn portion? If parts are heavily shaded, you could also start encouraging mosses in those bits. There's even some sun friendly mosses, though I don't know how they'd do in your zone.
If you're not walking on most of the lawn, you could also plant creeping thyme as general ground cover with clover as the "path" portion. I read that doing an entire lawn with creeping can get pricey, but they were talking about using plugs, not seeds, so you know. There are quite a few different kinds of creeping to choose from. The creeping will get woody over time, hence the suggestion to use the clover as the path.
