Q. See questions 2771-72 above – regarding fences separating backyards for the purpose of having a minyan). How about if there is no fence at all just shrubs and bushes, do they count as a mechitza? How tall can they be?
A. Horav Shlomo Miller’s Shlit’a opinion is that shrubs and bushes constitute a mechitza if they are ten tefachim high.
(Actually, as mentioned above they are more problematic since they are not see through. See also above the lenient opinion of the Mishna Berura).
Rabbi A. Bartfeld as advised by Horav Shlomo Miller and Horav Aharon Miller Shlit’a.
