Finally giving this place a review after several visits. I've read some other reviews and thought I would give my thoughts.
I would advise bringing water, sunblock, and comfortable shoes as there are two sides of the orchard. I would advise walking around both sides at first unless you feel pretty comfortable around the orchard.
I constantly see people tearing carrots/beets out of the ground which are clearly not done. Same goes with fruits and if you don't feel comfortable just watch/ask others. You can probably find a "how to" video on YouTube that tells you what to look for in each produce.
Yeah, they run out of certain items due to nature or demand. Just make sure you know what's in season before coming so you know what to expect.
P.S. An orchard doesn't always mean apple. If you google the term orchard it's the intentional planting for food production. Just thought I would clear that up for some people.
