Continuing from Shavuos to Va’eschonon

There is a common minhag to bring trees and shrubbery into the bais medrash for Shavuos. The custom of my ancestor, Rav Mordchele of Nadvorna zy”a, was so keep these plants there until after Shabbos Nachamu, Parshas Va’eschonon, when the Aseres Hadibros are read in the Torah. People testified that an open miracle occurred in that the plants remained fresh and crisp until they were taken down, weeks after being cut from the tree.
