Q.Planting around apple trees
I planted several apple trees in my yard last year and I would like to replace the grass around/under them with something else. Any ideas? I live in Zone 4-5 and would like a ground cover that would be tough near the road.

Sweet Woodruff would be an excellent ground cover and companion plant for under Apple Trees in Zones 4 - 5.
Here is a link with growing information.
