Investors & landlords

I’m in a rental property that has a massive backyard but it is all dirt and stickers. I want my kids to be able to use it but it would be very expensive to make it function. I want to ask the property owner who owns about 9 properties here if they will come to some kind of agreement and make it very appealing to them. Can the owner right off the expense if they are willing to invent in some landscaping so we can actually use the backyard?
