A bag worm infestation several months ago caused a 3-ft by 2-ft section of a 7-ft evergreen shrub to turn brown. While there are some signs of regrowth (green), the section is still very brown. Is there a recommended treatment / fertilizer that can help rejuvenate the shrub, and if so when should it be applied (a generally harsh midwestern winter is nearly upon us).

November is too late in the year to fertilize. Wait until next spring, just before new growth starts, and use a balanced fertilizer. Water the soil thoroughly before and right after applying it. The regrowth is a good sign. Plants can take quite an assault if they are healthy and still recover so don't prune until you determine if new growth will fill in. Good luck!
