Mr. Hoffman also planted asparagus around a tree at its drip line, the area below the outer limit of the branches.MARK HOFFMAN: "Now the asparagus is in partial shade. It has been there for six years now and is doing wonderfully. It is right at the drip line of the tree. So when it rains, all the rain drips down right on the asparagus."霍夫曼还在大树滴水线,也就是树枝覆盖范围正下方种植芦笋.霍夫曼:"现在芦笋就种在部分荫凉下,它们种下已经6年了,一直长势很好.它们刚好种在大树的滴水线下,所以每当下雨的时候,所有雨滴都刚好落在芦笋上."
