Actually you cannot get it directly you have to harvest its seeds first I recommend some dinos like trike paramour and gianthopithecas(I used).

Then you need crop plot (any medium or large or any else).

Then you need poop of your tames as fertilizer directly add poop in crop pot and water.

For water you can use pipes or you can use water jar or that leather water bag it is called something I forgot.

By the way after all these you have to wait I don't know exact time but I think 2 days of the game or less.

HOPE THIS HELP YOU.

THANK YOU ENJOYY!

(I know you guys want to make kibble as me so you need citronal).
