Single post in Mulch

Especially with the upcoming berry event, I feel it would be beneficial to let everyone know that you can only use mulch when you plant each berry. I dug (no pun intended) on the site for awhile and found no info about how to use mulch. The only place this info is readily available is in the wiki, which I never use being a desktop only player. I'm sure most people do use the wiki, but I know there are quite a few of us who just don't find it an easy, helpful resource to navigate. Perhaps letting people know on the berry event tab, in the garden, or when you buy the mulch itself could be good alternatives
