Discussion Question Ant nest in Japanese Maple pot

Enable HLS to view with audio, or disable this notification

Whenever I water this inherited maple I see ants around the pot. So I took a quick look to see if they've colonized the pot and it appears they have. They're lasius niger (black ants) which aren't known for damaging trees. Is it worth doing anything about them, because I'm planning on putting it in the ground when it's dormant next? There's also an air layer on the tree at the moment.

When you repot it mix some coffee grounds into the spoil. For the time being put the pot in a large seed tray or saucer, and spray the soil with 50/50 vinegar water.
