Is there a limit of real trees I can plant? How many can I plant?

The cost of planting real trees is donated by us. If every user could plant an unlimited number of real trees , the cost of planting would soon exceed our income from this app. Therefore, every user can plant at most five real trees.
​We will also come up with special events in the future, which include letting users plant more real trees than their limit, so keep an eye out for new events!
