Sown #11 answer

The solved garden

The seeds: R1C5, R2C3, R3C8, R4C4, R5C7, R6C1, R7C6, R8C9, R9C2 (R = row, C = column, counting from the top left). Every row, column and plot holds one seed, and no two seeds touch, not even diagonally.

A hard garden: Friday's puzzle. The hardest idea it needed was several plots that fill the same rows or columns between them.

How to crack it: the first moves

1. Every free square of the sunflower plot is in row 1, so the plot's seed must go there. Nothing else in row 1 can have one.
2. A seed in the square in row 2, column 6 would leave row 1 without enough room. So it stays empty.
3. A seed in the square in row 8, column 2 would leave the sand plot without enough room. So it stays empty.
4. All the free squares of the sand plot and the slate plot lie inside row 8 and row 9, and they need just as many seeds as those rows do. So those seeds all come from them: every other free square there stays empty.
5. The teal plot still needs one more seed, and only one free square is left. Sow it.
6. The pink plot still needs one more seed, and only one free square is left. Sow it.

Plots are named by their colour in the picture (sage, sunflower, lavender, coral, sky, pink, teal, sand, slate). Every Sown garden can be solved this way, one deduction at a time, without guessing.
