Rows of trees

Here's a puzzle that had me stumped for awhile:

How do you plant 10 trees in 5 rows of 4?

"Stumped," ha ha.

Eight of them side by side, with two outliers. The line of eight contains five embedded lines of four.

that's different that what I have in mind, but seems perfectly correct! there's at least one other way...

You draw a pentagram on the ground. Then you plant a tree at all 5 points of the pentagram, and then plant a tree at all 5 places where lines cross in the pentagram.

Each of the 5 lines of the pentagram will contain 4 trees.

OK then, smartie, how about in a cross, six and five in each line?

And I'm so with Darren about the box puzzle :-)

Well done, Mr. Kite.
