St. Charles, MO
|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!
