Hi, We have some arborvitaes that have some dead "limbs" on them. Can I prune the dead foliage off and when should I do this?

Arborvitae will withstand heavy pruning and shearing because new branches develop from concealed buds in the branch crotches. Prune in early spring or mid-summer. When heavy pruning is necessary, prune before new growth begins in early spring so that new growth conceals pruning cuts.
