But if it starts showing up more, a spray of baking soda and water 1/2tsp to a quart is a good preventative. You need to do it fairly often, especially after rain and overhead sprinkling since it will wash off.

Are you making sure to water in the mornings? Evening watering in summer is an open invitation to fungi to infect the leaves when they sit all night with water on them.

Yes, I switched to morning waterings, it fits well with my pattern, although I cut back a bit on this planter due to the moss growth, plus we've actually had rain in these parts for the last couple of days after that sweltering heat.
