Time to plant the trees.

Assuming interest on this puzzle is spent, let's close it out.

OK that counts as over-achievement I guess.

It's not the fewest trees that can make eighteen rows, but it probably is the fewest that can make twenty.

Honorable mention!

So the answer is 12 trees making 18 rows.

Can you draw the layout?

On the right track.

We need at least three trees per row.

Hi tammie, and welcome, if no one else has said it, to the Den.

Yes, you have it right.

There are 12 trees.

Eighteen rows have 3 and only 3 trees in them.

There is a "bonus" row, if you want to call it that, and it has 4 trees.

Shamelessly bumping this puzzle. It's worth the effort to solve, IMO.

12 trees making 18 rows of 3 trees each.

Past prime, actually.

I've been stuck on this one. Maybe it would help to know whether or not the following figure is a subset of the final answer, since I keep coming back to it and it seems to at least be a local minimum (or whatever the appropriate term would be)
