At the FanFest they said there would be player run farms next expansion but offered no additional details. We should be learning more at one of the remaining FanFests. It could be the farms will address some player concerns with the current gardening system.

I don't think gardening itself will be undergoing any changes outside the addition of new seeds. I would like better indicators for which plants were recently fertilized/tended since the gardening UI tends to cover up the current one if you're not at the right angle but not getting them wouldn't bother me. I've learned to be careful in checking what I'm doing.
