The lake of isle of Innisfree(poem) by William Butler Yeats

How many bean-rows does the speaker plan to have at Innisfree?

In the poem "The Lake Isle of Innisfree" by William Butler Yeats, the speaker plans to have nine bean-rows at Innisfree. This can be found in the third stanza of the poem:

"I will arise and go now, and go to Innisfree,
And a small cabin build there, of clay and wattles made:
Nine bean-rows will I have there, a hive for the honey-bee,
And live alone in the bee-loud glade."
