The only way to get rid of those roots, I suppose that's your
name for (wortelopslag) braches comming trough the lawn. Is
to cut them of on a regular base. 

Most lovely prunus varieties are put on (geënt) on wild 
seeldlings or selecter vars. Most of those heavy bloomers
have only a weak root.

Copper is a essential element in plantgrowt, but in very
small quantities, if the plant get's to much copper, it
becomes fytotoxic.
