Can you provide small palm tree maintenance, food ? Ants crawl all over them.
I try not fuss about ants in the garden since they clean up organic waste, help control pests, and their tunnels aerate the soil. However, if they aren’t welcome in your garden, you can add sticky traps to a plant, flood their nest, or use ant bait.
We do not have much experience with palms, so I recommend you contact your local garden center in this case. They should have a much better idea for your situation.
Thanks and sorry I couldn’t be more help on this one.
