How to "un-agricraft" seeds for witchery altar power?

Solution: Using a Phytogenic Insolator with rich phyto-gro (or something else idk this is the first time I've used this machine), the agricraft witchery seeds were turned into witchery seeds+product!

Apparently you can't get seeds like mandrake and whatever else without crossbreeding other seeds. This makes is so you have to use cropsticks with agricraft. So when you finally get those witchery seeds, they have the "Unidentified" text on them, and they can't ever be planted on the ground. Can only be planted on sticks.

This is a slight problem because I don't think the altar recognizes those seeds. I planted them near the witchery altar and the power did not go up at all.

Is there a way to un-agricraft the seeds? I need to plant them directly on the ground.

EDIT: It's infinity evolved expert mode. I accdentally posted this thread on another subreddit not related to minecraft and had to remove it. The modpack was specified in that post. When I tried to post it here it said I had to wait like 8 minutes and by then I had forgotten about the modpack specifics. Sorry about that
