Do we need to buy tickets before we arrive or can we come whenever and purchase tickets at farm?

I would recommend you drive there and park to check the weather before you make your purchase online right in your phone just in case because rain or shine, once you purchase there are no refunds or exchanges

Purchase ticket before you go ,this will save you money. The place is pricey

You can purchase them on Groupon. They are cheaper.

Yes purchase them b4 hand because it saves you like 5$ a ticket

I was asked to buy my tickets online before arriving.
