How much money to spend on Landscaping on a rental?

[Bryan Cavellier]

I own a duplex in a C class neighborhood. People are low income, but good people and generally speaking take care of their homes to an ok degree. My question is simple, how much money should I spend on landscaping as it is something that obviously doesn't drive home or rent value up all that much... is it THAT important to tenants? I obviously keep the grass well maintained and sidewalks clean but would some mulch and flowers beds be worth it or just another thing to maintain and not worth my time? Thanks as always BP!!!
