How To Kill Algae Growing In A Pot Filled With Wet Dirt?

Question

We removed a large bird of paradise from a pot but left half of the soil because it was too wet. I covered the pot to keep out more water but now that it’s been uncovered we find a thick coat of what looks like brown/green algae. We live in a condo on the fourth floor so it’s not that easy to get rid of wet dirt. We have just put old dirt in garbage bags and taken them down to put in trash containers when the trash company comes to our complex.

Answer 1

I would do like you have in the past and scoop out the algae into a trash bag.

You also can buy a moss killer to apply. When the moss dies you can scrape it out and put it into a trash bag.
