It is recommended to send the sacrificial animal to the Haram for one who does not intend to go there himself; It is reommended to garland it and to make the garland, but the one who sends it does not enter a state of Ihram, and nothing is forbidden to him because of that
Allah's Messenger (ﷺ) sent the sacrificial animals and I wove garlands for them with my own 'hands, and he did not refrain from doing anything which he did not avoid in the state of non-Muhrim.
