My parents just mow the lawn every now and then and remove thorny plants when they find them. The garden is just wild flowers and weeds. Then they dig a little pond. Since then they have lots of bees and other insects, but no wasps. It’s nice and requires no maintenance whatsoever. If a plant dies, it dies. If it takes over, it takes over. In spring until summer their whole garden is full of daisys. A white garden. The dog loves it and ears the heads off then when he’s chilling.
