This Coastal Redwood (Sequoia Sempervirens) needs to be thinned out in order to balance the tree’s allocation of energy. The right side is thicker and more full of foliage. If left unattended, it could be begin to hog all the tree’s nutrients , leaving the left side to become weaker and weaker and perhaps even die off. We can help to remedy this problem by pruning to a consistent density of foliage throughout the entire tree.
There are also a few branches and clusters of needles that have died off and must be removed in order to preserve the tree’s aesthetic integrity. Also, a good little lesson that I have learned many times the hard way, is to always cover the soil surface with a skirt/sheet when doing fine pruning work. It will save you the hassle of spending an hour picking out all those tiny leaves or pieces of wire that are lodged between bits of soil.
