In a rental who is responsible for cleaning gutters and cutting trees?

Question Details:

Landlord is charging me to clean gutters and cut trees. Neither is in my rental agreement. If I don't pay he said he'll increase my rent for the second time in a year. What are my rights? Rent has always been paid on time the last 5 years. This only came up a year ago after the third family in 4 years moved from other house on property. Important Notice
