I never noticed any bee or bumble bee coming out of the soil, and I dodn't know they nest in the ground.
The bees were almost 20, we have a beekeper really near our house so I guess they were his bees.
The problem is only for now, because the pots are really small and there are seeds inside, infact yesterday I found one of the seed out, on the surface.
I was afraid they could do some sort of damage.
If they nest in the garden no problem for me!
