Flower Puzzle

Anyone knows how to solve this part?

I'm confused as I thought that guessing was removed.

The one on the left is the weed.

The one on the right would make a circle, if it were the weed.

I have to disagree. The one on the left cannot be a weed as it will make the lower portion of the paths completely disconnected with the rest of the pathways. Therefore the right must be the weed

for sure the one on the left is a weed. and there is no guessing. As Mari said the one on the right would make a circle.

The one on the left is the weed.

The one on the right would make a circle, if it were the weed.

Sorry , I think Onion Knight misread Mari's answer and though weed means road instead of flower. 

Roads connect to each other only once , indicating that weed in right is flower.

It seems that road/weed is getting tricky for me. In this image I'll say flower to avoid any further confusionhttp://imgur.com/a/yPn19

Yes - I think we're all saying the same thing here, now that Onion Knight has clarified what he means- the right hand square must be the flower, and the left hand one must be the weed and needs to be cleared, to allow the roads in the bottom left corner to join up with the other roads.

And I'd just like to add a thank you to the devs for developing this "no pot luck guesses" version of the flower garden. It's SO much more satisfying to do now. And now that there are more quests that can use the flowers from the garden, there's an incentive to sometimes get it wrong too!

Thanks everyone I have been solving those puzzles and didn't know about those rules.
