The leaves on the lower branches of my beautiful Tilleul have begun to
sprout multiple growths,- the only way I can describe them is pyramid
shaped warts! They grow out on the upper side of the leaf. The tree
appears to be healthy otherwise, and the leaves remain green, although
these 'things' are yellowish. Is this a problem or is it normal?
