You may want to just pull the trigger and sell all of your harvest and not maintain your crops, but this will limit your growth in the long term if you don’t manage all of your crops. Make sure you always have seeds left over in your silo, don’t ever sell them all as you will eventually just have to buy them again from another farmer at a higher price.Also, keep in mind that every crop you plant will double the crop’s yield after harvest. No one wants to waste diamonds buying seeds that you used to have and sold for a few coins. It’s also good to have a steady supply of wheat, corn, and feed for your animals to maintain on.
