Followup on the Plant
From a couple days ago, here’s more info. It turns out it is a mesemb, and a Delosperma nubigenum to be precise.
Here’s some more pictures of the plant:
I’m San Francisco. Watering it once every 2 weeks with a few
tablespoons of water. Haven’t done anything to it recently—it’s been
sitting near the window since I bought it.
It’s a very hardy plant that can take a wide range of conditions, but I think in this case it may be not enough water since it’s a small pot. Rather than a little bit of water every 2 weeks, try drenching the soil, and letting the plant drain fully (Never let it sit in water), every 10 days.
You can clean out the dead leaves from the pot, but don’t be too aggresive – leave as much of the plant as you can.
Keep it in as sunny a window as you have and the plant should perk up pretty quickly. If it doesn’t, let me know.
