|how much do you prune off of the following plants?
green mountain boxwood
and do you do anything with elijah blue fescue
this is the first year for the plants
|The Goldmound spirea is usually trimmed back by about a third to a half in the spring to remove any winter damage. After the first big bloom flush, many gardeners will lightly shear the plant to deadhead it and encourage additional blooming later in the season.
Boxwoods require very little if any pruning, their natural shape is quite regular and even. If you need to trim off the occasional wayward tip, do that in the winter or spring or up until midsummer. Keep in mind this plant grows very slowly.
The azalea would not need much if any pruning. Keep in mind it blooms on old wood, so the best time to prune would be in late spring, immediately after it blooms.
The fescue like other ornamental grasses will die back in the fall. The dead foliage is trimmed back in late fall or very early spring, per your preference.
