Well, technically you can only plant crops if you have an EC. But here is what you do if you have one:
Click on the EC tab
Click meadow
It should show the meadows that you have for the horses in the EC
You have to lay a pasture fallow, and then you can grow crops, but you have to buy fertilizer and the certain crop that you want to grow.
first you have to make sure they are in season then go to a meadow select it by clicking inside the box and hit the plus sign at the bottom and choose the following "use meadow for growing crops"
if you have and equestrian center buy a meadow and lay it fallow then you can grow crops on it
You buy a meadow the seeds and then plant them in your meadow
You can't, unless you have a greenhouse.
When you plant seeds it will ask you if you want to use fertilizer or not.
