Gardening is a huge timesink and not fun most of time, would be nice to make it at least more comfortable. Spending hours just staying and tabbing through multiple seedlings to catch watering and fertilizing time is exhausting.

So I would suggest to add some cheap but effective visual indication on every stage of growth. Color change should be enough, just make it really noticeable. And make game automatically plant seeds in round or square patters around or in front of player. Right now they get planted randomly on top of each other. General idea is to be able to plant everything possible at same time and still clearly see every plant and what stage it's on.
