Answer: Your groundcover will have to compete with the tree for moisture, sunlight, and nutrients as well as cope with an acid soil. English ivy (Hedera helix) is an old standby but it would probably do well there. Vinca minor (creeping myrtle) is another possibility. If possible, add some compost or other organic soil amendments when you plant your groundcover and then be sure to water it as needed until it becomes established.
