Plants deeply (6)
I believe the answer is:
embeds
'plants deeply' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for embeds that I've seen before include "Fixes in something solid" , "Attaches to, as a journalist to a military unit to report a war" , "Sets or fixes firmly and deeply" , "Fixes firmly into surrounding mass" .)
