Money trees are a waste of money. The best way is to plant 30k, which has a 1 in 3 change of growing a money tree, which will give 90k, so if you plant three bags of 30k, you should get 90k back. So overall, the best shovel is the silver, for the bell -> ore rock conversion ^^
As I said in my post before, a 30k bag has a 1 in 3 chance of growing, it is all luck. Watering trees does nothing btw. And as I said, you will only loose money trying to make a money tree, which only has bells on once =]
They're not guaranteed to grow every time. Whether or not they grow depends on the amount buried - yet, as Glaceon said, there is really no point in burying more than 30k. Also, they only bloom once.
