Grafting Ornamental Plants with Wheat Kernel and Fragrant Tree Grafting

Description

The Chasam Sofer addresses whether inserting a wheat kernel into a plant cutting to aid rooting constitutes prohibited kilayim grafting, concluding that since the kernel disintegrates underground without growing above ground, one may rely on leniency though stringency is praiseworthy. On whether fragrant trees may be grafted onto one another, he argues that fragrance is not classified as fruit and would permit such grafting, but recommends stringency in practice due to an alternative Yerushalmi text and the Ramban's mystical rationale.
