They have the potential to sever the plant’s roots and cause its untimely death before it has ever had a chance.

Caffeine May Suppress Root Development

Compared to seedlings, older plants are less likely to be harmed by coffee grounds, but if you don’t want to take a chance on the health of a plant you really like, it’s still something to think about.

Worms are essential for breaking down compost and assisting in its decomposition, hence it would be detrimental to reduce the worm population. To get a firm conclusion, more investigation into this subject is necessary.
