Experts and BHG readers answer.
Planting under a pine tree
Growing plants under pines can be difficult not only because of the shade, but also because the shallow roots of the pine soak up all the moisture. Whatever you plant should be somewhat drought tolerant. And it would help to amend the soil where you plant with compost or other organic matter. Pulmonaria (lungwort) is one possibility. Others are hellebore, corydalis, and fringed bleeding heart.
