Each town should have about 16x16 inner linear squares for each Acre (attributed by previous games) and still by game factors in New Leaf. Usually a perfect town should consist of about 13-14 range of trees and about 3-5 flowers near a Villagers home (changes moods about gardening and perfecting a town on their behalf) and scattered 3-4 flowers for the acre.
Selecting the ordnance to BEAUTIFY 'NEW LEAF TOWN' PROJECT allows the Villagers to forcefully inherit the ability to water flowers and keep the balance of the Town. Not sure how this ordnance affects the Police Station items.
This game by far has the most acres that affect the game's Perfection. If ever completed, the Player will receive a Golden Watering Can that makes wilted flowers into GOLD FLOWERS used for presentation, faster hybrid breeding and nonwilting purposes. This ordnance also allows the flowers to not wilt when pondering into a time warp/timeturner/time travel effect. {Sometimes a player may use a differecnt 3DS and forget the time is mismatched and finds wilts in a town.}
It is more on over about the TYPE of town constructed/chosen and is based on the area that is balanced around you. Certain town maps have less beach front than others. This is recognized and the remarks from Isabelle on Villager views are fitted to the location of the town. More over, certain areas are patch work or bare stumped areas that have no trees or constructions; these are what Villagers worry on most.
Each sector has the ability to house more trees than any other game (for the exception of Animal Crossing 64/Gamecube's ability to cross plant trees side-by-side diagonally).
Villagers are more worried/concentrated/focused on their given constructions that are asked consequentially in a face-to-face conversation.
So far I have planted many trees all throughout town and the complaint remains "Not enough in one AREA", but I have not found any criteria listing them as acres.
The focus of the player's game is based on planting bamboos, making a planting center, and beatifying with many post around without the use of trees blocking their visibility as well.
"Perfect"/"Delicious" Gold Fruit are available by either making the uprighting of a town or by planting those had. It increases game points but as these trees are fragile be sure to plant each one found to keep ranking positive position points from Villagers.
Also, the use of grass is still wears but does not really affect perfection and is luckily slower than the previous ACCF game.
Suggestions: I do the same as well, as flowers scattered are hard to keep track of and the amount of trees in an area are easier to find exotic fruit apart from natives. Just construct from the Mayor's seat and do things that help the town.

From history, Dandelions are weeds that do not negatively affect town happiness and will eventually mature into dandelion puffs which can be blown away.
So they're weeds, though you don't necessarily have to pull them. You can even transplant them if you pick them before they turn into puffs. A hint to their weedy nature is that they take many more attempts to trample. 3 tramples will kill a flower, it takes more like 8 to kill a dandelion.

So after taking a few days for some testing, yes, flowers do heal fully if you water them, and it only takes one day for them to heal. If you trample something and don't water it, it'll just wilt (become brown) and then die easily to another trample/plucking.
I bought some flowers (Sun Cosmos and White Cosmos) from the Garden Shop so I knew that they were brand new and untrampled. I planted them both and ran over the White Cosmos once and the Sun Cosmos twice. I watered the Sun Cosmos and did not water the White Cosmos.
The next day, the White Cosmos (unwatered) was brown, so just one more trample/plucking would have killed it even though I originally trampled it once. I watered it and left it alone. The Sun Cosmos appeared to be fine, and I was able to run over it twice again.
The third day, the White Cosmos was back to full color again. I again ran over it twice without it dying. The Sun Cosmos was able to take another two tramples as well. I was originally going to not water the White Cosmos again, but it rained, so they were both watered.
The fourth day, today, I was able to run over both the White and Sun Cosmos twice.
Based on the fact that I was able to trample each flower twice after watering rather than just once, I'm forced to conclude that flowers fully regain their HP when you water them rather than just regaining a single HP each day. Otherwise, they would've died when I trampled them twice again each day afterwards.
