The clue above settles this square.
Clue 4 is the clever one. Zoe's panel is reed (3) or moss (4), and her number plus the mint panel's number makes seven. Only 3 and 4 add up to seven, so mint went on whichever of reed and moss Zoe did not paint. That means neither willow nor fern was painted mint, and Zoe did not use mint.
That is the whole method. Each clue settles a few squares, and those squares make the next clue useful.
