Shade to sun
Consider pruning, limbing up or removal to open up your space. Once you have a vision for the shape and scope your garden should take, you may find it necessary to prune, thin saplings or limb up your trees to create an environment that welcomes sunlight. You may also need to hire a good arborist to remove trees that are detracting from the overall feel of your garden or inhibiting your sight lines. This sometimes requires fortitude, but your garden will thank you in the end.
