Hi and welcome to my first (short) guide on how to get "Green Thumb" achievement that was one of the achievements recently added to the game. If you're 100% completionist like me, you'll probably gonna want to grab them all, but I found this one to be toughest of them.

First I wrote it on the Steam Discussion forum, but since not everyone might see it there and thanks to fsy inspiration I decided to post it here, so it can reach more people. Enjoy and happy watering!

Unfortunately, there is no indicator on the location of the flowers, so to make this Achievement easier for you, open Interactive Map[voxelse.github.io] Then you need to untick everything besides Flowers, like so:
In the top right corner you will find a compass, similar to the one in game:

Now go in game and using your compass to help you navigate you should be able to find missing flowers. Below is my recommended route.

To make this task faster, I recommend taking the route below. This will make this faster for you, and also if you're unsure if you watered a flower or not, you can follow it to double check the spots.

Good luck, now get those flowers watered!
