Hint: Grow a Golden Shovel
Bury a shovel anywhere and dig it up one day (24 hours) later. The shovel will become a Golden Shovel. Using the Golden Shovel, you can bury bags of money to hopefully grow money trees. Larger lumps of money increase the odds of growing a fruitful money tree.
Hint: Growing Fruit Trees
You can plant a piece of fruit to grow a tree that bears that fruit. However, not all parts of your town are suitable for growing. To ensure that your fruit tree grows, chop down an existing tree (preferrably one that dooesn't grow fruit) and dig up the stump with a shovel. Bury the fruit in the hole you dug and it will always grow into a fruit bearing tree
