So the garden patches are fairly useless as they are. 

I know people have suggested adding the ability to grow things like dandelions which would be good but they're still too slow to use. 

I'd suggest both a higher yield and the ability to re plant and or harvest in one input as I for one don't bother with them because you need to chop, collect, open menu, add crop, and fertilizer for each one which is slow enough that I'd rather just gather resources normally. 

 

What we need is a fresh water and salt water garden for the seaweed, pond moss, and other water flora.
