The 224th prohibition is that we are forbidden from working the land during the jubilee year.
The source of this prohibition is G‑d's statement,1 "[The 50th year shall be a jubilee to you in that] you may not plant," as commanded regarding the shemittah year,2 "you may not plant your fields."
Just as during the shemittah year one is prohibited from both working the land and the trees, so too during the jubilee. Therefore the general statement "you may not plant" is used, to include both the land and trees.
The punishment for transgressing this prohibition is also lashes.
