Last.

I've had this plant 6-8 weeks (?). Shortly after I got it home, it was infested with some black bugs I couldn't identify. Tried spraying with water, then resorted to Neem x1, which seemed to clear it up.

It is in full hot sun from about 10am to dusk now, on concrete and gravel. We have just come out of our very wet foggy mornings, so I will have to adjust watering. I'm paranoid about over watering, I admit. I usually just stick my finger in the pot to see if it's dry. :-(
