3,037. Changing Your Mind About Your Crop

Hilchos Kilayim 2:13

Let’s say that someone plants wheat in his field, but then he changes his mind and decides that he wants to plant barley instead. If the wheat has not yet sprouted, he must wait until the seeds decay and decompose in the ground, which would be three days in a well-watered field. He then turns over the soil with a plow and plants the barley. He need not turn over the whole field to the extent that not one kernel of wheat remains planted. Rather, he plows the field as one would before a rainfall so that it would be well watered.

Let’s say that the wheat already sprouted and then he changes his mind and decides that he wants to plant barley. In such a case, he must turn the field over and then plant it. If he lets his animal into the field and it eats what sprouted, then he may plant the other species.
