Every year we celebrate Arbor Day . Last year we we decided to celebrate the holiday by planing a tree . We went to the local plant nursery . We talked to the employees to find out which trees grow well in our area and in the type of soil we have . We chose a small maple seedling . When we got home , we chose an area of our yard with lots of sun . We dug a hole just a little bigger than the roots of our seedling . We put the seedling in the hole in the ground very carefully , then covered the roots with dirt . We patted the dirt down really good to make sure the little tree seedling would be stable in the ground when it was windy . Then we watered the tree . We 've been watching and watering our tree for a year and slowly but surely our little tree is growing .
What kind of tree was planted?
