horse chestnut tree
I have a potted horse chestnut tree that has a lot of grass and weeds in the pot. I think this is hindering the growth of the tree. What is the best way to get rid of the weeds and keep them out?

Hand-pulling is probably the best way to get rid of the weeds and then add a layer of mulch to keep new ones from sprouting. Use a weed killer on it may harm the tree.
