Is it true that the ficus benjamina tree, when grown outdoors, does not have a tap root?* A business recently had 2 trees removed in front of a historical location and said that the gardener had damaged the roots when he tilled the soil around the base of the tree in order to plant some decorative plants there.* They said that the trees fell over during the night but there are other suspected causes of removal.* These were trees that were about 20 years old and at least 20 feet tall.
Thanks for any help.
