Bay tree winter hardy? #372362

Asked October 24, 2016, 8:05 AM EDT

I live in Baltimore City, midtown, warmer here than Mt. Washington or Towson. I have a 5-year bay tree in a pot; about 2 ft tall with new growth from its summer outside. I have received conflicting answers re leaving it outside for the winter; have not so far, usually bring it inside. So my question to you is: can I leave my Bay tree outside for the winter? And, is there anything I should do to winterize it (mulch, cover, e.g.?). Thank you,  Baltimore City

Expert Response

The bay laurel is not hardy here and will have to be moved indoors before a frost (now). Inspect your plants for any insect problems.  You can spray with a growing rate of horticultural oil on the upper and lower leaves to prevent insect problems. Follow label directions.  See the attached link for overwintering indoors.  http://extension.illinois.edu/herbs/bay-laurel.cfm
