There's a couple changes I'd personally love to see in Gardening:
1. Move the remove plant option from the drop down and put it somewhere else on the page. I've been trying to grow maya seeds and every time I accidentally click on remove when I'm watering them I have a mild heart attack. If someone were to remove a plant, check the box to not show the "are you sure?" warning again, completely forget about it, and at some point accidentally remove a plant they really wanted while trying to water it that would hurt.
2. It would be convenient to have a way to water plants without constantly having to open the drop down menu. Maybe an option for upgraded accounts to give them an extra perk?
3. Tangentially related, but when exchanging seeds please don't let the menu see inside your vault! I grew a crystal apple and stored it, but it still shows up on the exchange list. This is a super minor nitpick, I know. I know myself well enough that there's a chance I'm not thinking clearly and trade something that I stored to try and protect from myself, haha!
