In Seedlings it says we can plant seeds and such at Veta Lake, but I wasn't able to find anywhere? Are we actually able to start gardens? If so, where would I find it?

It's the little red barn in Veta, direct link

I don't use it though so that's about all the help I can give you for it xD

Ahh thank you both very much :D Frederick is bothering me to collect all of the plants.
