Tree canopy blocking sunlight to lawn — Hilversum, Noord-Holland

When mature trees develop dense canopies, the grass below thins and dies from lack of sunlight. Moss, bare dirt, and weeds replace turf in heavy shade. Simply reseeding fails because new grass needs at least 4 hours of filtered sunlight daily. An arborist or landscaper can crown-thin the canopy (selectively removing 15–25% of branches) to let light through without harming the tree, then overseed with shade-tolerant grass varieties like fine fescue.
