I've got all the tools, fertilisers, bug sprays, seeds and everything the farm girl was willing to sell. I cannot find any garden upgrades when talking to Ellen though. And when I go to Jin, there's no way to give her the seeds either.
Also: carrot, cabbage, onion, elfish hoop, senti and tinu seed packs are all greyed out, but I still can buy them. I've loaded an older save game and I won't do that now, but... I guess it either shouldn't be greyed out or the buttons should be disabled.
