How do you water the flower next to a tree to unlock the harvest spirit in Harvest Moon Tree of Tranquility

Ok, before you start watering the plants, you need to get the whole quilt. Once you ship at least 1,000g worth of items Hamilton will talk to you about it. Once you ship some more, he will talk to you again and then he will give you the left half. Then you go over and talk to Gill (the mayor's son) about the harvest sprites. To get the right half, you talk to Dale (the carpenter) and he will tell you about the broken clock tower in the town square. After that, you talk to Hamilton and you ask him about the clock tower. Then you offer to fix it and he will give you the key. You go over to the clock tower in the Town Square and open it up. Inside you find the right half of the quilt and a note from Alan ( I think ). Then you take your watering can and water the flowers under the certain trees.
