Tartan tree
Note: You must have Tartan for this glitch to work.
Normally, you arean't supposed to be able to mix crops or flowers with trees to get a different result, but in this case you can.
1: Take any crop in seed form and upgrade it to S rank with the UP-Seed. (You have to have Tartan to make hybrids)
2: Take desired B-Rank tree you wish to make S-Rank and place it in the first slot of Tartan.
3: Take the S-Rank crop and place it in the second slot.
4: MAKE SURE THAT THE B-RANK TREE IS IN THE FIRST SLOT AND S-RANK CROP IS IN THE SECOND IN ORDER FOR THE GLITCH TO WORK
5: Use Tartan and there you go, an S-Rank tree without wasting thousands on fertilizer.
